Question

Has Palmetto GBA finalized its coverage determination for Cardiac Resynchronization Therapy (CRT)?

Answer

Yes. The coverage determination became effective December 12, 2021 and can be found in Palmetto GBAs’ Local Coverage Article A58821 (link) and Palmetto GBAs’ Local Coverage Determination L39080 (link).

As with most of the other Medicare coverage guidelines, CRT has specific diagnosis codes that must be submitted on the claim to support medical necessity. In addition, the medical record must have documentation of the patient’s QRS duration - reflected in milliseconds - from the EKG, as well as documentation of QRS morphology such as right / left bundle branch block. Check the LCA and LCD for complete coverage requirements.

Fiscal Year 2021 Estimated Improper Payment Rates

In mid-November 2021, the Comprehensive Error Rate Testing (CERT) program published the Fiscal Year (FY) 2021 Annual CERT Report. A related Press Release, (link) noted that “CMS’ aggressive corrective actions led to an estimated $20.72 billion in reduction of Medicare Fee-for-Service (FFS) improper payments over seven years.”

While CMS cites an impressive reduction in improper payments over seven years, there was only a slight change from 2020 to 2021.

• Improper Payment Rate
• o FY 2020: 6.27%
• o FY 2021: 6.26%
• Improper Payment Amount
• o FY 2020: $25.74 billion
• o FY 2021: $25.03 billion

As I have noted in past articles, CMS noted in the Press Release that “while fraud and abuse may lead to improper payments, it is important to note that the vast majority of improper payments do not constitute fraud, and improper payment estimates are not fraud rate estimates.”

Fiscal Year 2021 Supplemental Improper Payment Data

The 2021 Supplemental Improper Payment Data Report (link) was published on December 12, 2021. This report highlights common causes of improper payments and includes tables allowing you to drill down into the review findings.

COVID-19 Impact

• From March 27, 2020, until August 10, 2020, CERT program activities were suspended,
• CMS reduced the claim sample size for FY 2021 (claims submitted July 1, 2019, through June 30, 2020), and
• Claims with dates of service within the COVID-19 PHE were reviewed in accordance with all applicable CMS waivers and flexibilities.

“0 or 1 day” Length of Stay Claims

Since implementation of the Two-Midnight Rule, the supplemental data report has included a table comparing improper payments rates for Part A hospital claims by length of stay (LOS). The improper payment rate for “0 or 1 Day” stay claims was highest in 2014 at 37.18% and in 2021 hit an all-time low of 16.8%. However, with the project improper payment rate being $1.5 billion, it is not surprising that Two-Midnight Stays are currently on the OIG Work Plan (link) and Livanta as the National Medicare Claim Review Contractor (link), is focusing their review efforts solely on Short Stay Reviews (SSRs) and Higher Weighted DRG (HWDRG) reviews.

Top 20 Service Types with Highest Improper Payments: Part A Hospital IPPS Table D4 of this report includes the top 20 DRG types with the highest improper payment rate. The table also details the percentage of error by each of the CERT’s major error categories:

• No documentation,
• Insufficient documentation,
• Medical Necessity,
• Incorrect Coding, and
• Other.

Overall, 58.9% of the errors in this table were due to the error category medical necessity. The CERT places a claim into this category when the CERT contractor reviewers receive adequate documentation from the medical records submitted to make an informed decision that the services billed were not medically necessary based upon Medicare coverage and payment policies. One hundred percent of the errors for the following four DRG Types was attributed to medical necessity:

• DRG 069: Transient Ischemia,
• DRGs 308, 309, 310: Cardiac Arrhythmia & Conduction Disorders,
• DRG 312: Syncope, and
• DRG 313: Chest Pain.

Moving Forward

For the Septicemia DRGs 871 and 872, 37.2% of the errors was attributed to “no documentation.” Unfortunately, denied claims due to no documentation is also a frequent issue reported by the Medicare Administrative Contractors (MACs) and the Supplemental Medical Review Contractor (SMRC).

Moving forward, here are ideas and resources to help in your efforts to prevent claims errors:

• Visit the CERT Provider Website (link) to find information about the CERT, how to submit records, sample request letters and much more.
• Become familiar with National and Local Coverage Determinations and Local Coverage Articles that detail indications and limitations of specific services. For example, DRGs 469 and 470 (Major Hip and Knee Joint Replacement or Reattachment of Lower Extremity) had the highest projected improper payment in Table D4 at $724,055,597. The CERT attributed 19.5% of the error to insufficient documentation and 80.3% to medical necessity. CMS has published an MLN Booklet titled Major Joint Replacement (Hip or Knee) (link) that provides guidance on what to document to avoid denied claims.
• Become familiar with and utilize your hospital’s Program for Evaluating Payment Patterns Electronic Report (PEPPER).
• And finally, take the time to review the CERT’s Supplemental Improper Payment Data report annually.

A related article in this week’s newsletter (link), provides detail from the 2021 Comprehensive Error Rate Testing (CERT) program annual report and annual supplement data to the report. This article provides key facts about the CERT.

About the CERT

• The objective of the CERT program is to monitor and report the accuracy of claims payment in the Medicare Fee-for-Service program.
• CMS uses the CERT error rate to evaluate the performance of the Medicare Administrative Contractors (MACs).
• There are two CERT contractors:
• The CERT Review Contractor (CERT RC), and
• CERT Statistical Contractor (CERT SC).
• The CERT claim selection includes a stratified random sample of approximately 50,000 claims that are chosen by claim type (Part A, Part B and Durable Medical Equipment, Prosthetics, Orthotics, and Supplies (DMEPOS), and includes paid and denied claims by the MAC.
• The CERT process is a federally mandated program and not responding to documentation requests will result in a denial of all services billed on the claim.
• CERT request letters are mailed to the correspondence address listed in the Provider Enrollment, Change and Ownership System (PECOS).
• You can submit requested documentation to the CERT via postal mail, fax, Electronic Submissions of Medical Documentation (esMD), via CD or via email attachment(s).
• For short (less than 24 – 48 hours stay) inpatient hospital stay, a discharge summary is not required when a beneficiary is seen for minor problems or interventions, as defined by the medical staff. In this instance, a final progress note may be substituted for the discharge summary.
• The billing provider is responsible for obtaining medical records from the third-party to substantiate the claim that was billed.
• The CERT makes every effort to obtain the request documentation. Providers have 45 days to respond to the first letter requesting documentation. When the CERT does not receive the requested documentation by the 75th day, a claim is counted as a non-response error and is subject to overpayment recovery by the MAC.
• Claims reviews by the CERT includes program checks for compliance with Medicare statutes and regulations, billing instructions, National Coverage Determinations (NDCs), Local Coverage Determinations (LCDs), Local Coverage Articles (LCAs), and provision in the CMS instructional manuals.
• Denied claims as well as overpayments and underpayments are all considered to be an improper payment by the CERT program.
• Improper payments are attributed to one of five major error categories (no documentation, insufficient documentation, medical necessity, incorrect coding, or other).
• The improper payment rate is not a “fraud rate,” but a measurement of payments that did not meet Medicare requirements.
• Providers that wish to appeal a CERT contractor’s determination can follow the normal redetermination process to appeal all CERT denials.
• The CERT A/B MAC Outreach & Education Task Force has a goal to ensure consistent communication and education to reduce the Medicare Part A and Part B error rates. The Task Force webpage (link) includes education resources for providers.

January 24, 2022: Free At-Home COVID-19 Tests

The CDC’s January 24th COVID-19 updates included a notice (link) that “every home in the United States is eligible to order 4 free at-home COVID-19 rapid antigen tests. Orders will usually ship in 7-12 days. These tests give results within 30 minutes (no lab drop-off required).” You can also go to https://www.covidtests.gov/ to order your tests.

Over the past thirteen years, part of my job has been to review medical records. When thinking about Social Determinants of Health (SDOHs), I distinctly remember one project where I reviewed three separate admissions for the same patient. Digging into the charts, I noted the patient’s discharge status was consistently to “tent city.” Unfortunately, tent cities are not a phenomenon limited to the Southeastern United States. Also unfortunately, this is a perfect example of a SDOH that can negatively impact an individual’s health outcomes.

Did You Know?

Social Determinants of Health (SDOHs) and Z Codes

Z codes first became available with the implementation of ICD-10-CM codes on October 1, 2015. Z code categories Z55 – Z65 are related to SDOHs. Eleven new codes became effective on October 1, 2021, bringing the list to a total of 109 codes.

New FY 2022 SDOH Z codes

• Z55.5 – Less than a high school diploma,
• Z58.6 – Inadequate drinking-water supply,
• Z59.00 – Homelessness unspecified,
• Z59.01 – Sheltered homelessness,
• Z59.02 – Unsheltered homelessness,
• Z59.41 – Food insecurity,
• Z59.48 – Other specified lack of food,
• Z59.811 – Housing instability, housed, with risk of homelessness,
• Z59.812 – Housing instability, housed, homelessness in past 12 months,
• Z59.819 – Housing instability, housed unspecified, and
• Z59.89 – Other problems related to housing and economic circumstances.

In January 2020, the CMS published an initial Data Highlight focused on the utilization of Z codes among Medicare Fee-for-Service Beneficiaries in 2017 (link). The authors suggested that “reducing reliance on clinicians to capture SDOH, improving provider and medical coder education, and filling gaps in codes, among other policy-based interventions, would likely improve the reporting of SDOH coding across care settings.”

In September 2021, the CMS published a follow-up Data Highlight titled, Utilization of Z Codes for Social Determinants of Health among Medicare Fee-for-Service Beneficiaries, 2019 (link).

September 2021 Data Highlight Key Findings

Barriers to increasing documentation of Z codes

• Z code claims are not generally used for payment purposes,
• There are a limited number of Z codes and sub-codes meaning some social, economic, and environmental determinants may not be captured,
• While there are providers who may have had training regarding SDOH and recognize challenges some of their patient’s face, “they may feel limited in what they can do and/or may require guidance on how best to assist patients in addressing their non-medical needs.”

Data Highlight Authors Conclusions

• “More widely adopted and consistent documentation of them is needed to comprehensively identify non-medical factors affecting health and to track progress toward addressing them; doing so could aid in work toward achieving health equity and ensuring highest quality and best-value care for all beneficiaries.”
• “It will be critically important to carefully analyze data from 2020 and 2021 to understand whether and to what extent the public health emergency (PHE) may have had an impact on social, economic, and environmental determinants, and/or the rate of documentation of those determinants via Z codes.”
• “All members of the US health system: payers, patient-centered medical homes, hospitals, national organizations, governments at the local, State, and Federal level, communities, providers, patients, as well as other stakeholders all have an important role to play in identifying social, economic, and environmental determinants, and ultimately improving health outcomes.”

RealTime Medicare Data CY 2020 Z Code Analytics

Analysis of CY 2020 Medicare Fee-for-Service paid claims data provided by our sister company, RealTime Medicare Data (RTMD), reinforced the current underuse of SDOH Z codes. For instance,

• Less than 1% of claims include a SDOH Z code for the Inpatient Hospitals, Outpatient Hospital and Part B places of service,
• Ninety-four percent of the claims were Hospital Outpatient claims, and
• Z59.0 (Homelessness) was the top Z code used in all three places of service.

MMP has compiled a high-level summary of the data analysis that can be downloaded here (link).

Using Z codes to Advance Health Equity

The American Hospital Association has been advocating for utilization of SDOH Z codes and publishing education for Providers since 2015 and have recently updated their ICD-10-CM Coding for Social Determinants of Health Fact Sheet (link).

In the January 13, 2022 edition of MLN Connects (link), the CMS promotes awareness of January being National Poverty in America Awareness Month noting that “37.2 million Americans living in poverty have an increased risk of chronic conditions, lower life expectancy, and barriers to quality health care; and racial and ethnic minorities have poverty rates more than twice that of white Americans. The COVID-19 pandemic has significantly affected these populations and low-income families.”

CMS is also promoting the use of Z codes to help advance health equity for all Americans by identifying poverty, unemployment, homelessness, and other social determinants.

Moving Forward

Ensure that key stakeholders in your facility (i.e., Physicians, Nurses, Social Workers, Case Managers, CDI Specialists, Registered Dieticians) receive education about SDOH and coding ICD-10-CM Z codes. A good place to start is with the guidance found in the ICD-10-CM Official Guidelines for Coding and Report FY 2022 (link). Additional resources available for your education efforts includes:

• CMS’ Using Z Codes infographic: (link)
• Office of Disease Prevention and Health Promotion – SDOH webpage: (link)
• CDC’s SDOH webpage: (link)
• AHA’s SDOH webpage: (link)

Did You Know?

January is Thyroid Awareness Month.

Why Should You Care?

As a health care consumer, it is important to understand what the thyroid gland does, what thyroid hormone impacts and what can happen when your thyroid gland is not functioning properly. According to the CDC (link)

• The thyroid gland, located in the front of the neck just below the Adam’s apple, takes iodine from your diet and makes thyroid hormone. Thyroid hormone affects your physical energy, temperature, weight, and mood.
• In general, there are two broad groups of thyroid disorders: abnormal function and abnormal growth (nodules) in the gland.
• Thyroid disorders are common, especially in older people and women. Most thyroid problems can be detected and treated.
• Abnormal function is usually related to the gland producing too little thyroid hormone (hypothyroidism) or too much thyroid hormone (hyperthyroidism).
• Benign nodules in the thyroid are common, usually do not cause serious health problems, can occasionally put pressure on the neck and cause trouble with swallowing, breathing, or speaking if too large.
• Thyroid cancers are much less common than benign nodules and with treatment, the cure rate for thyroid cancer is more than 90 percent. You can learn more about Thyroid Cancer and the annual Medicare Treatment costs of Thyroid Cancer in a related RealTime Medicare Data (RTMD) infographic in this week’s newsletter.

As a health care provider, it is important to be aware that MS-DRGs 625, 626, and 627 (Thyroid, Parathyroid & Thyroglossal Procedures with MCC, with CC, without CC/MCC respectively), have been under scrutiny by the Comprehensive Error Rate Testing (CERT) and Supplemental Medicare Review Contractor (SMRC).

The 2018 CERT Medicare Fee-for-Service Improper Payment Rate Report noted an improper payment rate of 49.1% for this DRG group. Subsequently, in February 2020, CMS tasked Noridian, as the SMRC, to perform data analysis and DRG validation reviews of the same DRG group. Noridian published their review results in October 2021 (link) citing a 12% error rate.

What Can You Do?

As a healthcare consumer:

• Have your doctor check for thyroid disease during a standard physical exam by palpation of the thyroid gland.
• There are two standard blood tests that your doctor may recommend. One measures your thyroid hormone level (T4) and another measures thyrotropin (TSH) which is hormone secreted from the pituitary gland that controls how much thyroid hormone your thyroid makes.

Treatment for thyroid disease will be specific to the type and severity of the thyroid disorder and the age and overall health of the patient.

As a healthcare provider, one of the reasons cited by the SMRC for errors was providers not responding to requests for documentation within 45 calendar days of the additional documentation request (ADR). Noridian has a Documentation Requests webpage (link) which includes a link to an example ADR letter which provides guidance on how you can submit medical records.

In December 2021, the FDA announced (link) an Emergency Use Authorization (EUA) for AstraZeneca’s Evusheld (tixagevimab co-packaged with cilgavimab and administered together) for pre-exposure prophylaxis (prevention) of COVID-19 in certain adults and pediatric individuals (12 years of age and older weighing at least 40 kg [about ">link) pounds]).

According to the announcement, Evusheld is for people not currently infected with or who have not had recent exposure to an individual who has COVID-19. Additionally, the EUA requires that the individual either have:

• “moderate to severely compromised immune systems due to a medical condition or due to taking immunosuppressive medications or treatments and may not mount an adequate immune response to COVID-19 vaccination (examples of such medical conditions or treatments can be found in the fact sheet for health care providers) or;
• a history of severe adverse reactions to a COVID-19 vaccine and/or component(s) of those vaccines, therefore vaccination with an available COVID-19 vaccine, according to the approved or authorized schedule, is not recommended.”

The FDA reinforces the fact that this medication is not a substitute for a COVID-19 vaccine and “urges the public to get vaccinated if eligible.” They also advise patients to talk with their health care provider to determine if this is an appropriate prevention option.

CMS has updated their COVID-19 Vaccines and Monoclonal Antibodies webpage (link) to include the code and the national payment allowance for Evusheld.

Also, CMS reminded providers in the December 16 edition of MLN Connects (link) that “if you vaccinate or administer monoclonal antibody treatment to patients enrolled in Medicare Advantage (MA) plans on or after January 1, 2022, submit claims to the MA Plan. Original Medicare won’t pay these claims.”

Did You Know?

The advice from Coding Clinic has changed regarding Anxiety with Depression.

Coding Clinic, 1st Quarter 2021, page 10 advises that Anxiety with Depression should be coded as two separate conditions, unless the physician has documented a link between the two. We are not to assume the linkage. If documentation does link the two conditions together, then F41.8, Other Specified Anxiety Disorders should be assigned.

Please note that this advice has been updated from Coding Clinic, 3rd Quarter 2011, page 6, which previously instructed us to code Anxiety with Depression as one condition.

Why It Matters?

It is important to correctly capture the clinical picture of the admission by coding the correct ICD-10 codes. Also, the Depression codes have been recently revised.

What Can I Do?

Review both Coding Clinics and the Oct. 1, 2021, coding changes with the coding staff.

Coding Clinic, 1st Quarter 2021, page 10 Coding Clinic, 3rd Quarter 2011, page 6

Did You Know?

Malnutrition and more specifically, severe malnutrition has been in the audit spotlight for several years. Historically, the OIG completed a series of reviews of hospitals with claims that included the ICD-9 diagnosis code for Kwashiorkor (260). In a December 2017 Report Brief (link), the OIG “reviewed the medical records for 2,145 inpatient claims at 25 providers and found that all but 1 claim incorrectly included the diagnosis code for Kwashiorkor, resulting in overpayments in excess of $6 million.”

They identified a discrepancy in the ICD-CM coding classification between the tabular list and the alpha index on the use of diagnosis code 260 and stated “CMS did not have adequate policies and procedures in place to address this discrepancy, resulting in a total potential loss of approximately $102 million during CYs 2006 through 2015. Even though CMS was aware of the discrepancy, it did not take any separate action to address it.”

In July 2020, the OIG published a Report Brief (link), looking at ICD-10-CM severe malnutrition diagnosis codes E41 (nutritional marasmus) and E43 (unspecified severe protein calorie malnutrition). The OIG found that 164 of 200 claims had billing errors resulted in net overpayments of $914,128 and stated, “the errors occurred because hospital used severe malnutrition diagnosis codes when they should have used codes for other forms of malnutrition or no malnutrition diagnosis code at all.” Based on the sample of claims reviewed, the OIG estimated hospitals received overpayments of $1 billion for FYs 2016 and 2017.

Most recently, in November 2021, the OIG added a review of Medicaid inpatient hospital claims with severe malnutrition to their Work Plan (link). The Work Plan issue description, indicates “adding an MCC to a claim can result in an increased payment by causing the claim to be coded in a higher diagnosis-related group.”

In addition to the OIG, the Q3 Fiscal Year (FY) 2021 Program for Evaluation Payment Patterns Electronic Report (PEPPER) became available and includes the new risk area, severe malnutrition. More specifically, this new PEPPER Target Area focuses on DRGs assigned based on an MCC with one of the following malnutrition ICD-10-CM diagnosis codes as the only MCC:

• E40: Kwashiorkor
• E41: Nutritional Marasmus
• E42: Marasmic kwashiorkor
• E43: Unspecific severe protein-calorie malnutrition

The Thirty-Fourth Edition of the Short-Term Acute Care PEPPER User’s Guide (link) provides the following guidance for hospitals that are high outliers for this new risk area:

“This could indicate that there are coding errors related to unsubstantiated coding of one of the severe malnutrition codes (i.e., E40, E41, E42, or E43) as the only MCC. A sample of medical records with a severe malnutrition code as the only MCC should be reviewed to determine whether coding errors exist. A diagnosis of severe malnutrition must be determined by the physician. A coder should not code based on laboratory findings or nutritional consultation without seeking physician determination of the clinical significance of the abnormal findings.”

Severe Malnutrition by the Numbers

As severe malnutrition has been and continues to be a focus of audit, I turned to our sister company RealTime Medicare Data (RTMD) to try and understand how often one of the above severe malnutrition ICD-10-CM diagnosis codes continues to be the only MCC coded on a record. RTMD data is Medicare Fee-for-Service specific and includes inpatient discharges, outpatient services, and CMS 1500 Professional services. It is full-census, non-modeled, and typically available 90 days post-payment.

The data provided by RTMD for this article includes calendar years (CYs) 2019 and 2020 inpatient claims for the entire RTMD footprint. Here is what I found.

CY 2019 and 2020 combined:

• 188,383 total claims paid where a severe malnutrition code was the only MCC on the claim.
• Actual Total Payment: Just over $2.9 billion
>
• The five states with the highest number of claims for both CYs included Florida, California, New York, Texas, and Illinois.

CY 2019:

• 102,874 total paid claims
• Actual Total Payment: $1,543,413,978
• Volume of claims by ICD-10-CM diagnosis code:
• E40 Kwashiorkor – 13 claims
• E41 Nutritional Marasmus – 235 claims
• E42 Marasmic Kwashiorkor – 4 claims
• E43 Unspecified severe protein-calorie malnutrition – 102,622 claims
• Claims where one of the four severe malnutrition codes was the only secondary diagnosis on the claim:
• 8,506 claims
• Actual Total Payment: $114,480,291

CY 2020

• 85,509 claims
• Actual Total Payment: $1,367,094,959
• Volume of claims by ICD-10-CM diagnosis code:
• E40 Kwashiorkor – 12 claims
• E41 Nutritional Marasmus – 117 claims
• E42 Marasmic Kwashiorkor – 10 claims
• E43 Unspecified severe protein-calorie malnutrition – 85,370 claims
• Claims where one of the four severe malnutrition codes was the only secondary diagnosis on the claim:
• 8,101 claims
• Actual Total Payment: $114,246,389

Moving Forward

• Make sure key stakeholders (i.e., Physicians, Coding Professionals, Clinical Documentation Integrity Specialists, and Registered Dieticians) at your facility are familiar with the 2012 ASPEN/AND criteria and the 2018 Global Leadership Initiative on Malnutrition (GLIM) criteria,
• Partner with your medical staff to standardize the criteria your hospital uses to define the types of malnutrition (i.e., Kwashiorkor, Nutritional Marasmus),
• Monitor your quarterly PEPPER to see if your hospital is an outlier in this risk area,
• Respond in a timely manner to medical record requests made by auditing entities.
