CMS released the 2,087 page display copy of the FY 2023 IPPS Final Rule (CMS-1771-F) on Monday August 1, 2022. This article highlights finalized changes to calculating relative weights and MS-DRG Refinements.

Calculating MS-DRG Relative Weights

CMS notes, in a related Fact Sheet, it is reasonable to assume Medicare beneficiaries will continue to be hospitalized with COVID-19 in FY 2023. They also believe admissions will be fewer than is reflected in the FY 2021 data.

Based on these assumptions, CMS finalized calculating relative weights for FY 2023 by:

• Calculating two sets of relative weights, one including and one excluding COVID-19 claims, and
• Averaging the two sets of relative weights to determine the final FY 2023 relative weights.

You can find the updated relative weights, geometric and arithmetic mean LOS and which MS-DRGs are designated as a post-acute DRG in the Final Rule Table 5.

For FY 2023, MS-DRG 018 (Chimeric antigen Receptor (CAR) T-Cell and Immunotherapies) has the highest relative weight at 36.1452 and MS-DRG 795 (Normal Newborn) has the lowest relative weight at 0.2024.

MS-DRG Refinements

The number of MS-DRGs will remain the same at FY 2022 at 767. Also, there were not as many MS-DRG refinements made FY 2023 as in years past.

Acute Respiratory Distress Syndrome (ARDS)

CMS received a request to reassign cases reporting diagnois code J80 (Acute respiratory distress syndrome) as the principal diagnosis from MS-DRG 204 (Respiratory Signs and Symptoms) to MS-DRG 189 (Pulmonary Edema and Respiratory Failure). The requestor noted that in the ICD-10-CM Tabular List of Diseases, per the Excludes 1 note under category J96 (Respiratory Failure, not elsewhere classified) only code J80 should be assigned when respiratory failure and ARDs are both documented. Currently, a principal diagnosis of J80 groups to MS-DRG 204.

CMS data analysis supported this request and finalized their proposal to reassign cases with ARDS (code J80) as the principal diagnosis from MS-DRG 204 to MS-DRG 189.

Claims Analysis

In Calendar Year (CY) 2021, in the RealTime Medicare Database (RTMD) database, there were 255 claims sequenced to MS-DRG 204 (Respiratory Signs and Symptoms) with a principal diagnosis of J80 (ARDS). Based on the CMS FY 2022 Final Rule, the shift from MS-DRG 204 to MS-DRG 189 would result in:

• An increase in the MS-DRG Relative Weight (R.W.) of 0.4325, and
• An increase in the MS-DRG National Average Payment of $2,612.56.

For the 255 claims with a principal diagnosis of J80 (ARDS) in CY 2021, the reassignment to MS-DRG 189 would result in a $666,202.80 increase in payment for this group of claims.

Cardiac Mapping

CMS identified a replication issue from ICD-9 based MS-DRGs to ICD-10 based MS-DRGs for procedure code 02K80ZZ (Map conduction mechanism, open approach). Cardiac mapping describes the creation of detailed maps to detect how the electrical signals that control the timing of the heart rhythm move between each heartbeat to identify the location of rhythm disorders. Cardiac mapping is generally performed during open-heart surgery or performed via cardiac catheterization.

This code is currently recognized as a non-O.R. procedure that affects the MS-DRG to which it is assigned. CMS finalized their proposal to reassign this code from MS-DRGs 246, 247, 248, 249, 250, and 251 to MS-DRGs 273 and 274 (Percutaneous and Other Intracardiac Procedures with and without MCC, respectively)

Laparoscopic Cholecystectomy with Common Bile Duct Exploration

A requestor noted that when a laparoscopic cholecystectomy is reported with any one of the listed procedure codes with a common bile duct exploration and gallstone removal procedure that is performed laparoscopically and reported with procedure code 0FC94ZZ, the resulting assignment is MS-DRGs 417, 418 and 419 (Laparoscopic Cholecystectomy without C.D.E. with MCC, with CC, and without CC/MCC, respectively). This MS-DRG assignment does not recognize that a common bile duct exploration (C.D.E.) was performed.

CMS finalized their proposal to redesignate procedure code 0FC94ZZ from a non-O.R. procedure to an O.R. procedure and add it to the logic list for common bile duct exploration (CDE) in MS-DRGs 411, 412, and 413 (Cholecystectomy with C.D.E. with MCC, with CC, and without CC/MCC, respectively).

Claims Analysis

In CY 2021, in the RTMD database, there were 188 claims that sequenced to the MS-DRG group 417, 418, and 419 (Laparoscopic Cholecystectomy without C.D.E. with MCC, with CC, and without CC/MCC respectively) that included the procedure code 0FC94ZZ describing a common bile duct exploration procedure with removal of a gallstone.

Based on the CMS FY 2023 Final Rule, following are the shifts in R.W. and geometric mean LOS by DRG severity levels:

• The increase from MS-DRG 417 to MS-DRG 411 (Chlecystectomy w/C.D.E. w/MCC) in R.W. is 1.0005 and the increase in geometric mean LOS is 1.0 day,">link
• The increase from MS-DRG 418 to MS-DRG 412 (Cholecystecomy w/C.D.E. w/CC) in R.W. is 0.6347 and the increase in geometric mean LOS is 1.1 days, and">link
• The increase from MS-DRG 419 to MS-DRG 413 (Cholecystecomy w/C.D.E. w/o CC/MCC) in R.W. is 0.3154 and increase in geometric mean LOS is 0.6 day.

CMS issued a display copy of the FY 2023 IPPS Final Rule (CMS-1771-F-IFC) on Monday, August 1, 2022. This article contains a high-level look at the final operating payment rate, quality program payments, and Social Determinants of Health (SDOH).

Payment Rate Change

The proposed increase in operating payment rates for general acute care hospitals paid under the IPPS that successfully participate in the Hospital Inpatient Quality Reporting (IQR) Program and are meaningful electronic health record (EHR) use was 3.2%. CMS finalized an increase of 4.3%.

Overall, the increase in operating and capital IPPS payments rates will generally increase hospital payments in FY 2023 by $2.6 billion.

Quality Programs

Hospital Value Based Purchasing (VBP) Program

This is a budget-neutral program where 2% of all participating hospitals base operating MS-DRG payments are used for funding and then redistributed back as a value-based incentive payment.

For FY 2023, CMS will pause several measures limiting the number of measures available for accurate scoring. For this reason, CMS will not calculate a Total Performance Score (TPS) and instead, each hospital will receive a value-based incentive payment amount to match their 2% reduction in base-operating payment.

Hospital Acquired Condition (HAC) Reduction Program

This program reduces payment by 1% for all hospitals that rank in the worst performing quartile on select measures. For FY 2023, CMS is pausing measures that would have been used to calculate a Total HAC Score. Therefore, no hospital will be penalized under this program for FY 2023.

Hospital Readmissions Reduction Program (HRRP)

The HRRP program reduces payments to hospitals with excess readmissions for unplanned readmissions within 30 days of the index admission for the following conditions or procedures:

• Acute myocardial infarction (AMI),
• Chronic Obstructive Pulmonary Disease (COPD),
• Pneumonia (PNA),
• Coronary Artery Bypass Graft (CABG) surgery, and
• Elective primary total hip arthroplasty and/or total knee arthroplasty (THA/TKA).

Beginning in FY 2023, all six conditions/procedure measures will be modified to include a risk adjustment for history of COVID-19 within 12 months prior to the index admission.

Social Determinants of Health

There are 96 diagnosis codes describing Social Determinants of Health (SDOH) in the subset of Z codes in categories Z55-Z65 (Persons with potential health hazards related to socioeconomic and psychosocial circumstances). Three of these codes are new and will be effective October 1, 2022:

• Z59.82: Transportation insecurity,
• Z59.86: Financial insecurity, and
• Z59.87: Material hardship.

In the proposed rule, CMS requested comments on issues related to SDOHs noting that “if SDOH Z codes are not consistently reported in inpatient claims data, our methodology utilized to mathematically measure the impact on resource use, as described previously, may not adequately reflect what additional resources were expended by the hospital to address these SDOH circumstances in terms of requiring clinical evaluation, extended length of hospital stay, increased nursing care or monitoring or both, and comprehensive discharge planning.”

Specific to the question regarding codes in category Z59 (Homelessness), many commenters agreed that codes describing homelessness have been underreported and increasing the severity level of the codes from a non-complication or comorbidity (Non-CC) to a complication of comorbidity (CC) could result in increased documentation and reporting of this condition.

CMS notes that will take comments into consideration for future rulemaking.

Did You Know?

The way brush biopsy is coded changed October 1, 2017.

Why It Matters?

Prior to 2017 ICD -10 did not have the option to choose Extraction for the Root Operation. At that time, the only option was to select “Excision”.

Definitions of Excision and Extraction:

1. Excision is the cutting out or off, without replacement, a portion of a body part
2. Extraction is the pulling or stripping out or off all or a portion of a body part with the use of force.

Physicians like to use the “brush” technique as it is low risk and the least invasive, but still provides enough cells to the Pathologists to make a diagnosis.

In addition, it is important to note the difference between the two approaches because the physician may obtain a specimen using both Excision and Extraction during an operative episode.

For example, during a Bronchoscopy, the physician may perform a brush biopsy of the bronchus and a transbronchial lung biopsy. To obtain a lung biopsy, tiny forceps are used to remove lung tissue, so this would be coded to the approach Excision. The lung biopsy carries a higher risk because there is a chance a pneumothorax will occur. The endoscopic lung biopsy will also group the DRG to a higher weight, which is another reason for being aware of these two approaches.

What Can I Do?

Review Coding Clinic, 4th Quarter 2017, page 41. Closely review the Op Report documentation and note the root operations used during the procedure.

Did You Know?

Novavax COVID-19 Vaccine, Adjuvanted (NVX-CoV2373) is a new COVID-19 vaccination that the FDA has approved for Emergency Use Authorization (PHE) for individuals 18 years or older (link).

Why is Matters?

This is the first protein-based COVID-19 vaccine to receive Emergency Use Authorization and CDC endorsement (link) in the United States. This vaccine is to be administered as a series of two doses given three weeks apart. It is not authorized for use as a booster dose.

According to an HHS Press Release (link), “The Novavax COVID-19 vaccine is designed and manufactured differently than the mRNA COVID-19 vaccines. The Novavax COVID-19 vaccine contains SARS-CoV-2 recombinant spike protein, which is also known as an “antigen” of the SARS-CoV-2 virus, in combination with an adjuvant, which enhances the immune system response to the spike protein.

FDA-approved protein-based vaccines have been used widely for decades; examples of more recently approved vaccines that contain a purified protein combined with an adjuvant include vaccines to prevent hepatitis B and shingles. The Novavax COVID-19 vaccine offers an option to individuals who may be allergic to a component in the mRNA vaccines, or who have a personal preference for receiving a vaccine other than an mRNA-based vaccine.”

What Can You Do?

As a health care professional review the CDC’s overview and safety information about this vaccine (link), and become familiar with how to code and bill for this newly vaccine.

Coding and Billing

CMS issued new codes for this vaccine, effective July 13.

• Vaccine code: 91304,
• Administration codes: 0041A and 0042A,

Did You Know?

August is National Immunization Awareness Month (NIAM). According to the CDC (link), NIAM “is an annual observance held in August to highlight the importance of vaccination for people of all ages.”

Why It Matters?

Immunity from childhood vaccines can wear off over time. Maintaining current with your immunizations throughout life helps you combat vaccine preventable diseases. The CDC advises (link) that all adults need:

• COVID-19 vaccine,
• Influenza (flu) vaccine every year, and
• Tetanus and diphtheria (Td) or Tetanus, diphtheria, and pertussis (Tdap) vaccine every ten years.

On a personal note, I received a Tetanus shot on my twenty-first birthday, making it easier to remember to get an updated Tdap shot on my thirty-first, forty-first, and most recently fifty-first birthday.

Forgive me for getting on my soap box for a minute, a vaccination to prevent shingles is also a must for adults. Having watched my mother suffer through the agonizing pain of shingles, I ask the question, why would you suffer through this disease when two doses of Shingrix provides strong protection against shingles and postherpetic neuralgia (PHN)? In fact, the CDC cites that “in adults 50 to 69 years old with healthy immune systems, Shingrix was 97% effective in preventing shingles; in adults 70 years and older, Shingrix was 91% effective (link). This series of two vaccines was my gift to myself when I turned fifty.

One more request is that you consider receiving a pneumonia vaccine. Based on the following CDC stats about Pneumonia in the United States, as a nation, we could do better.

• In 2020, the percent of adults aged eighteen and over who had ever received a pneumococcal vaccination was 25.5%.
• Data from 2018 revealed that 1.5 million emergency department visits had a primary diagnosis of pneumonia.
• Mortality data from 2020 revealed there were 47,601 deaths from pneumonia and deaths per 100,000 population was 14.4.

There are four pneumococcal vaccines licensed for use in the United States by the Food and Drug Administration:

PCV13: Prevnar 13® (pneumococcal conjugate vaccine or PCV13) is a registered trademark by Wyeth LLC and marketed by Pfizer Inc. This vaccine provides protection against infections caused by six more serotypes than PCV7. This vaccine is part of the routine childhood immunization schedule. Additionally, in 2011, it was licensed by the FDA for use in adults 50 years or older. The CDC recommends PCV13 for

• All children younger than 2 years old, and
• People 2 years or older with certain medical conditions.

The CDC advises adults 65 years and older to discuss the need for this vaccine with their health care provider.

PCV 15: Vaxneuvance™ (Pneumococcal 15-valent Conjugate Vaccine)

On July 16, 2021, Merck announced (link) the FDA approval of Vaxneuvance™, a new vaccine for the prevention of invasive pneumococcal disease in adults 18 years and older caused by 15 serotypes.

PCV20: Prevnar 20™ (Pneumococcal 20-valent Conjugate Vaccine)

On June 8, 2021, Pfizer announced (link) the FDA approval of the Prevnar 20™ vaccine for adults 18 years or older and noted that it is “the first approval of a conjugate vaccine that helps protect against 20 serotypes responsible for the majority of invasive pneumococcal disease and pneumonia, including seven responsible for 40% of pneumococcal disease cases and deaths in the U.S.”

PPSV23: Pneumovax23® (pneumococcal polysaccharide vaccine or PPSV23) is a Merck product. This vaccine was approved by the FDA in 1983 and helps protect against twenty-three types of pneumococcal bacteria. The CDC recommends this vaccine for

• All adults 65 years or older,
• People 2 through 64 years old with certain medical conditions (i.e., diabetes, heart disease or COPD), and
• Adults 19 through 64 years old who smoke cigarettes.

What Can You Do?

As a healthcare provider, work with your patients to identify what vaccinations they have and have not received and utilize available resources on the CDC website for healthcare providers related to vaccinations, for example:

• Immunization Schedules Resources for Health Care Providers: https://www.cdc.gov/vaccines/schedules/hcp/resources.html, and
• Adult Vaccination Information for Healthcare and Public Health Professionals: https://www.cdc.gov/vaccines/hcp/adults/index.html.

As a healthcare consumer:

• Keep your vaccination records up to date (link),
• Use the CDC’s Adult Vaccine Assessment Tool (link) to determine which vaccines are recommended for you, and
• Share all this information with your healthcare provider so you make an informed decision on what immunizations you may need.

CMS recently released the Calendar Year (CY) Outpatient Prospective Payment System (OPPS) and Ambulatory Surgical Center (ASC) Payment System proposed rule. In last week’s newsletter (link) we reviewed proposed changes to the Inpatient Only (IPO) List. This week’s focus is on the Ambulatory Surgery Center Covered Procedure List (CPL) and the Hospital Outpatient Prior Authorization Program proposals.

Ambulatory Surgery Center (ASC) Covered Procedure List (CPL)

The CMS evaluates the ASC CPL yearly to determine whether to add or remove specific procedures from the list. Covered surgical procedures performed on or after January 1, 2022, are:

• Procedures specified by the Secretary and published in the Federal Register,
• Separately paid under the OPPS,
• Would not be expected to post a significant safety risk to a Medicare beneficiary when performed in an ASC, and
• Standard medical practice dictates the expectation that the beneficiary would not typically require active medical monitoring and care at midnight following the procedure.

For CY 2023, CMS proposed to add one procedure to the ASC CPL:

• CPT 38531 (Biopsy or excision of lymph node(s); open, inguinofemoral node(s)).

RTMD Data Analysis

I turned to our sister company, RealTime Medicare Data (RTMD) to help estimate the potential impact to hospital outpatients if this procedure can also occur in an ASC setting. The claims data represents Medicare Fee-for-Service paid claims in calendar year 2021 for CPT 38531 for all states in the RTMD footprint. Currently, this includes all states except Kentucky and Ohio.

• Overall Claims Volume: 4,606
• CPT Payment: $13,088,298.18
• Top 5 States
• California had 411 claims with a payment of $1,468,801.23,
• Florida had 338 claims with a payment of $939,648.34,
• Texas had 253 claims with a payment of $705,682.74,
• Pennsylvania had 245 claims with a payment of $721,419.95, and
• New York has 229 claims with a payment of $651,816.93.

CMS ends this section of the proposed rule by noting they “believe that any additions to the CPL should be added in a carefully calibrated fashion to ensure that the procedure is safe to be performed in the ASC setting for a typical Medicare beneficiary. We expect to continue to gradually expand the ASC CPL, as medical practice and technology continue to evolve and advance in future years. We encourage stakeholders to submit procedure recommendations to be added to the ASC CPL, particularly if there is evidence that these procedures meet our criteria and can be safely performed on the typical Medicare beneficiary in the ASC setting.”

Hospital Outpatient Prior Authorization Program

The Prior Authorization for Certain Hospital Outpatient Department (OPD) Services initiative became effective on July 1,2020 and made a prior authorization request (PAR) a condition of payment for specific service categories. Service categories effective July 1, 2020, included:

• Blepharoplasty,
• Botulinum toxin injections,
• Panniculectomy,
• Rhinoplasty, and
• Vein ablation.

Effective July 1, 2021, CMS added cervical fusion with disc removal and implanted neurostimulators as new service categories.

You can learn more about this initiative on the CMS Hospital OPD Services initiative webpage (link).

CMS has proposed to add Facet Joint Interventions as a new service category and would include facet joint injections, medial branch blocks and facet joint nerve destruction CPT codes. This list of applicable CPT codes is in Table 79 of the proposed rule. If finalized, this would be effective for dates of services on or after March 1, 2023.

CMS Data Analysis

CMS performed data analysis of CPT codes 64490-64495 (Facet Injections and Medical Branch Blocks) and CPT Codes 64633-64636 (Nerve destruction services). Analysis revealed facet joint intervention claims volume increased by 47 percent between 2012 and 2021. This reflected a 4 percent average annual increase which is higher than the 0.6 percent annual increase for all outpatient department services.

Contractor Scrutiny

As part of the discussion for adding facet joint interventions to this initiative, CMS includes discussion of prior audits performed by the OIG and Department of Justice.

• OIG Report Medicare Improperly Paid Physicians for More Than Five Spinal Facet-Joint Injections Sessions During a Rolling 12-Month Period (A-09-20-03003) published October 2020 (link): The OIG found that MACs in the 11 jurisdictions with a coverage limitations made improper payments of $748,555.
• OIG Report Medicare Improperly Paid Physicians for Spinal Facet-Joint Denervation Sessions (A-09-21-03002) published December 2021 (link): The OIG found that Medicare improperly paid physicians $9.5 million.

In addition to past reports, there are two active OIG Work Plan items related to facet joint procedures.

• In the Department of Justice case reference in the proposed rule, the DOJ reported on a $250 million health care fraud scheme where “to obtain prescriptions, the evidence showed that the patients had to submit to expensive, unnecessary and sometimes painful back injections, known as facet joint injections.”

CMS notes, “both our data analysis and research show that the increases in volume for these procedures are unnecessary, and further program integrity action is warranted.”

RTMD Data Analysis

I once again turned to RTMD to help estimate the potential impact of adding Facet Joint Interventions to the prior authorization initiative. Keep in mind that data volume includes all procedures and there may be claims that could include multiple facet procedures in the same encounter.

Facet Injections and Medical Branch Blocks (CPT 64490-64495)

• Overall Claims Volume: 391,410
• CPT Payment: $141,144,372.81
• Top 5 States
• Texas had 40,472 claims with a payment of $13,102,475.35
• California had 24,109 claims with a payment of $11,433,125.41,
• Massachusetts had 23,738 claims with a payment of $9,892,874.58,
• New York had 18,901 claims with a payment of $6,922,608.02, and
• Pennsylvania had 18,624 claims with a payment of $6,764,696.64.

Facet Joint Nerve Destruction (CPT codes 64633-64636)

• Overall Claims Volume: 185,564
• Sum CPT Paid: $124,386,756.18
• Top 5 States
• Texas had 19,051 claims with a payment of $12,335,211.47,
• California had 11,620 claims with a payment of $10,144,086.72,
• Florida had 8,641 claims with a payment of $4,970,708.01,
• Illinois had 8,023 claims with a payment of $4,782,664.98, and
• Pennsylvania had 7,711 claims with a payment of $5,205,371.13.

CMS is accepting comments on the proposed rule through September 13, 2022.

• For a post COVID-19 condition, unspecified, like Long COVID, use code DX U09.9. Add other codes for conditions related to the COVID-19 infection, like R50.9 for fever.
• For a current COVID-19 infection, use code DX U07.1. Do not use code DX U09.9.
• For a current COVID-19 infection and conditions from a previous COVID-19 infection, use code U09.9 with code DX U07.1. Add other codes for conditions related to the COVID-19 infection, like R06.02 for shortness of breath.
• For more information, see pages 30-31 of ICD-10-CM Official Guidelines for Coding and Reporting: Fiscal Year 2022 (PDF).

July 13, 2022: CDC Releases Resistant Infections Special Report

The CDC released a report (link) detailing the negative effect of the COVID-19 pandemic on recent years of progress in the United States combating antimicrobial resistance (AR). In a related announcement, the CDC noted the report “concludes that the threat of antimicrobial-resistant infections is not only still present but has gotten worse – with resistant hospital-onset infections and deaths both increasing at least 15% during the first year of the pandemic.”

July 15, 2022: COVID-19 Public Health Emergency Renewed

CMS waited until late Friday, July 15th to post an extension of the COVID-19 public health emergency (PHE) (link). This extends the PHE for ninety days.

CCMS announced the release of the CY 2023 Physician Fee Schedule Proposed Rule in a special edition of their MLN Connects e-newsletter (link). You will find links to related fact sheets and the proposed rule in the newsletter. Comments are due to CMS by September 7, 2022.

July 7, 2022: Appropriate Use Criteria (AUC) Penalty Phase Delayed Again

CMS as posted the following notice on the AUC Program webpage (link), “The payment penalty phase will not begin January 1, 2023 even if the PHE for COVID-19 ends in 2022. Until further notice, the educational and operations testing period will continue. CMS is unable to forecast when the payment penalty phase will begin.”

July 16, 2022: New Nationwide 988 Crisis Hotline

HHS announced in a July 15th Press Release (link), the transition from the 10-digit National Suicide Prevention Lifeline to 988 “an easy-to-remember three-digit number for 24/7 crisis care…The 988 Suicide & Crisis Lifeline is a network of more than 200 state and local call centers supported by HHS through the Substance Abuse and Mental Health Services Administration (SAMHSA).”

True to form, the CMS announced the release of the Calendar Year (CY) 2023 Outpatient Prospective Payment System (OPPS) and Ambulatory Surgical Center (ASC) Payment System proposed rule late last Friday July 16th. This week we review the proposed changes to the Inpatient Only (IPO) list.

CMS once again reminds providers in this proposed rule that “Designation of a service as inpatient only does not preclude the service from being furnished in a hospital outpatient setting but means that Medicare will not make payment for the service if it is furnished to a Medicare beneficiary in the hospital outpatient setting (65 FR 18443). Conversely, the absence of a procedure from the list should not be interpreted as identifying that procedure as appropriately performed only in the hospital outpatient setting (70 FR 68696).”

Before reviewing proposals, here is a quick look back at the “flip flopping” of CMS over the past two calendar years. In CY 2021, CMS removed 298 musculoskeletal-related services from the IPO List and finalized the elimination of the list over three years. In CY 2022, CMS did an about face and finalized the following changes:

• The IPO list will not be eliminated over three years,
• Most procedures removed from the IPO list in CY 2021 were added back to the list for CY 2022, and
• The five longstanding criteria for determining whether a service or procedure should be removed from the IPO list was codified in regulation text.

Calendar Year 2023 Proposed Procedures for Removal from the IPO List

CMS is proposing to remove ten procedures from the IPO list.

CPT code 16036 (Escharotomy; each additional incision (list separately in addition to code for primary procedure)). This code is an add-on code typically billed with primary procedure CPT 10635 (escharotomy; initial incision) which was removed from the IPO list in CY 2007.

CPT code 22632 (Arthrodesis, posterior interbody technique, including laminectomy and/or discectomy to prepare interspace (other than for decompression), single interspace; each additional interspace (list separately in addition to code for primary procedure)). This code is an add-on code typically billed with primary procedure CPT 22630 (Arthrodesis, posterior interbody technique, including laminectomy and/or discectomy to prepare interspace (other than for decompression), single interspace; lumbar), which was removed from the IPO list in CY 2021. Note, this code was removed from the IPO list in CY 2021 and replaced back on the list for CY 2022.

The remaining eight procedures proposed for removal from the IPO list are all maxillofacial procedures removed from the IPO list in CY 2021 and replaced back on the list for CY 2022:

• CPT code 21141 (Reconstruction midface, lefort I; single piece, segment movement in any direction (e.g., for long face syndrome), without bone graft).
• CPT code 21142 (Reconstruction midface, lefort I; 2 pieces, segment movement in any direction, without bone graft).
• CPT code 21143 (Reconstruction midface, lefort I; 3 or more pieces, segment movement in any direction, without bone graft).
• CPT code 21194 (Reconstruction of mandibular rami, horizontal, vertical, C, or L osteotomy; with bone graft (includes obtaining graft)).
• CPT code 21196 (Reconstruction of mandibular rami and/or body, sagittal split; with internal rigid fixation).
• CPT code 21347 (Open treatment of nasomaxillary complex fracture (lefort II type); requiring multiple open approaches).
• CPT code 21366 (Open treatment of complicated (e.g., comminuted or involving cranial nerve foramina) fracture(s) of malar area, including zygomatic arch and malar tripod; with bone grafting (includes obtaining graft)); and
• CPT code 21422 (Open treatment of palatal or maxillary fracture (lefort I type);).

Calendar Year 2023 Proposed Additions to the IPO List

CMS has proposed the addition of eight newly created codes by the AMA CPT Editorial Panel to the IPO list for CY 2023:

• 157X1 (Implantation of absorbable mesh or other prosthesis for delayed closure of defect(s) (i.e., external genitalia, perineum, abdominal wall) due to soft tissue infection or trauma,
• 228XX (Total disc arthroplasty (artificial disc), anterior approach, including discectomy to prepare interspace (other than for decompression); second interspace, lumbar (List separately in addition to code for primary procedure),
• 49X06 (Repair of anterior abdominal hernia(s) (i.e., epigastric, incisional, ventral, umbilical, spigelian), any approach (i.e., open, laparoscopic, robotic), initial, including placement of mesh or other prosthesis when performed, total length of defect(s); greater than 10 cm, incarcerated or strangulated),
• 49X10 (Repair of anterior abdominal hernia(s) (i.e., epigastric, incisional, ventral, umbilical, spigelian), any approach (i.e., open, laparoscopic, robotic), recurrent, including placement of mesh or other prosthesis when performed, total length of defect(s); 3 cm to 10 cm, incarcerated or strangulated),
• 49X11 (Repair of anterior abdominal hernia(s) (i.e., epigastric, incisional, ventral, umbilical, spigelian), any approach (i.e., open, laparoscopic, robotic), recurrent, including placement of mesh or other prosthesis when performed, total length of defect(s); greater than 10 cm, reducible,
• 49X12 (Repair of anterior abdominal hernia(s) (i.e., epigastric, incisional, ventral, umbilical, spigelian), any approach (i.e., open, laparoscopic, robotic), recurrent, including placement of mesh or other prosthesis when performed, total length of defect(s); greater than 10 cm, Incarcerated or strangulated,
• 49X13, (Repair of parastomal hernia, any approach (i.e., open, laparoscopic, robotic), initial or recurrent, including placement of mesh or other prosthesis, when performed; reducible), and
• 49X14 (Repair of parastomal hernia, any approach (i.e., open, laparoscopic, robotic), initial or recurrent, including placement of mesh or other prosthesis, when performed; incarcerated or strangulated).

All proposed changes to the IPO list, including the CPT code, longer descriptor, proposed action (deletion or addition), proposed status indicator and for proposed deletions the proposed APC assignment are listed in Table 46 of the proposed rule.

CMS is accepting comments on the proposed rule through September 13, 2022.
