Question

What code do we assign when the Place of Occurrence or the Activity the patient was doing when an injury occurred is not documented?

Answer

Per the 2023 Coding Guidelines, Y92.9, Place of Occurrence or Not Applicable and Y93.9, Unspecified Activity, are not to be assigned when the information is not documented.

CMS published the CY 2024 OPPS/ASC Proposed Rule on July 13, 2023. By now, many news outlets have authored articles about this proposed rule. This article highlights topics that historically our clients have reached out to us to learn about.

Medicare Inpatient Only (IPO) Procedure List

Although CMS received several requests recommending services for removal from the IPO list, CMS did not find sufficient evidence that met the criteria and did not propose to remove any service from the IPO list for CY 2024.

CMS has proposed to add nine services with newly created codes by the AMA CPT Editorial Panel which will be in effect January 1, 2024 to the list and to reassign CPT code 0646T (Transcatheter tricuspid valve implantation (ttvi)/replacement with prosthetic valve, percutaneous approach, including right heart catheterization, temporary pacemaker insertion, and selective right ventricular or right atrial angiography, when performed) from status indicator “E1” to status indicator “C.” The proposed changes are available in Table 47 of the proposed rule.

OPPS Payment Methodology for 340B OPPS Payment Methodology for Purchased Drugs and Biologicals

On July 7, 2023, CMS published a proposed rule, referred to as “remedy proposed rule” to address reduced payment amounts to 340B hospitals for CYs 2018 through 2022 and to comply with the statutory requirement to maintain budget neutrality. The “remedy proposed rule” proposes changes to the calculation of the OPPS conversion factor beginning in CY 2025.

In the “remedy proposed rule,” CMS proposes to make one time lump-sum payments to each of the approximately 1,600 340B covered entity hospitals. Addendum AAA to the proposed rule lists the proposed lump-sum payment for each eligible hospital.

For CY 2024, CMS proposes to continue to pay the statutory default rate, which is generally ASP plus 6 percent.

340B Modifiers “JG” and “TB”

The Inflation Reduction Act of 2022 expanded the provider types that must report one of these modifiers no later than January 1, 2024 to now include critical access hospitals, Maryland All-Payer or Total Cost of Care Model Hospitals, and Non-excepted off-campus provider-based departments (PBD).

In the CY 2023 OPPS/ASC final rule, CMS maintained the requirements that 340B hospitals report one of two modifiers, “JG” – Drug or biological acquired with 340B drug pricing program discount, reported for informational purposes, or “TB” – Drug or biological acquired with 340B drug pricing program discount, reported for informational purposes for select entities.

In the CY 2024 OPPS/ASC proposed rule, CMS notes they “now believe utilizing a single modifier will allow for greater simplicity, especially because both modifiers are used for the same purpose: to identify separately payable drugs and biologicals acquired under the 340B program.”

CMS is proposing that all 340B covered entity hospitals would report the “TB” modifier effective January 1, 2025, even if the hospital previously reported the “JG” modifier. The “JG” modifier will remain effective through December 31, 2024. Beginning January 1, 2025, the “JG” modifier would be deleted.

CMS notes hospitals currently using the “JG” modifier could choose to continue to use it in CY 2024 or choose to transition to the “TB” modifier during that year.

Payment for Intensive Cardiac Rehabilitation Services (ICR) Provided by an Off-Campus Non-Excepted Provider Based Department (PBD) of a Hospital

CMS identified a disparity in payment for ICR services between services provided in a physician’s office and the same services provided by an off-campus, non-excepted PBD and notes that this “creates a significant barrier to beneficiary access to an already underutilized service.”

To eliminate this unintended outcome CMS is proposing the following:

“Pay for ICR services provided by an off-campus, non-excepted provider-based department of a hospital at 100 percent of the OPPS rate for CR services (which is also 100 percent of the PFS rate) rather than at 40 percent of the OPPS rate,” and

“Effective January 1, 2024, we propose to exclude ICR from the 40 percent Relativity Adjuster policy at the code level by modifying the claims processing of HCPCS codes G0422 (Intensive cardiac rehabilitation; with or without continuous ECG monitoring with exercise, per session) and G0423 (Intensive cardiac rehabilitation; with or without continuous ECG monitoring without exercise, per session) so that 100 percent of the OPPS rate for CR is paid irrespective of the presence of the “PN’’ modifier (signifying a service provided in a non-excepted off-campus provider-based department of a hospital) on the claim.”

Proposed Additions to the ASC Covered Procedures List (CPL) for CY 2024

CMS is proposing to update the ASC CPL by adding 26 dental surgical procedures. They note that they “expect to continue to gradually expand the ASC CPL, as medical practice and technology continue to evolve and advance in future years,” and encourage stakeholders to submit procedure recommendations to be added to the ASC CPL.

Appropriate Use Criteria (AUC) for Advanced Diagnostic Imaging

Although this falls under the purview of the CY 2024 Physician Fee Schedule Proposed Rule, I often receive questions from clients regarding when CMS plans to fully implement this program.

In the proposed rule, CMS notes that they “exhausted all reasonable options for fully operationalizing the AUC program,” and “propose to pause implementation of the AUC program for reevaluation and rescind the current AUC program regulations from §414.94.” They “expect this to be a hard pause to facilitate thorough program reevaluation and, as such…are not proposing a time frame within which implementation efforts may recommence.”

The comment period for the CY 2024 Hospital OPPS/ASC and Physician Fee Schedule Proposed Rules ends on September 11, 2023. I encourage you to take the time to review the proposed rules and submit comments.

June 2023: MLN Fact Sheet Telehealth Services Revised

CMS has recently updated this Fact Sheet and notes that they have made significant updates to explain recent policy changes. https://www.cms.gov/files/document/mln901705-telehealth-services.pdf

There are five covered indications in section B of National Coverage Determination (NCD) 20.7 Percutaneous Transluminal Angioplasty (PTA) for when PTA is covered.  

In June 2022, the Multispecialty Carotid Alliance (MSCA) submitted a letter to CMS for reconsideration of covered indication B4 (concurrent with carotid stent placement in patients at high risk for carotid endarterectomy (CEA).

Last week, on July 11, 2023, CMS published Proposed Decision Memo CAG-00085R8: Percutaneous Transluminal Angioplasty (PTA) of the Carotid Artery Concurrent with Stenting. CMS notes, the scope of this reconsideration is limited to PTA concurrent with CAS including transcarotid artery revascularization (TCAR) procedures.

CMS summarizes that their proposals, which affect NCD 20.7 sections B4 and D, will revise Medicare coverage for PTA of the carotid arteries concurrent with stenting by:

1. Expanding coverage to individuals previously only eligible for coverage in clinical trials.
2. Expanding coverage to standard surgical risk individuals by removing the limitation of coverage to only high surgical risk individuals.
3. Removing facility standards and approval requirements.
4. Adding formal shared decision-making with the individual prior to furnishing CAS; and
5. Allowing MAC discretion for all other coverage of PTA of the carotid artery concurrent with stenting not otherwise addressed in NCD 20.7.

CAS By the Numbers

Moving Forward

CMS is seeking comments on whether the shared decision-making interaction should require the use of a validated shared decision-making tool and/or if there are other options to achieve the goal of truly informed decision-making. The comment period is from July 11, 2023 through August 10, 2023.

Did You Know?

The 2024 ICD-10-CM Official Guidelines for Coding and Reporting were posted to the CMS website on July 6, 2023 (https://www.cms.gov/medicare/icd-10/2024-icd-10-cm). You can also find the guidelines on the CDC ICD-10-CM webpage (https://www.cdc.gov/nchs/icd/Comprehensive-Listing-of-ICD-10-CM-Files.htm).

Why It Matters?

“These guidelines have been developed to assist both the healthcare provider and the coder in identifying those diagnoses that are to be reported. The importance of consistent, complete documentation in the medical record cannot be overemphasized. Without such documentation accurate coding cannot be achieved. The entire record should be reviewed to determine the specific reason for the encounter and the conditions treated.” As of July 19^th, there are only 73 days to become familiar with the October 1, 2023, changes.

Narrative guideline changes appear in bold text in this document.

What Can You Do?

For Coding and Clinical Documentation Integrity professionals, reading the new guidelines should be a requirement on your summer reading list. In addition to identifying the bolded text, pay attention to each time the guidelines tell you to query the provider if documentation is unclear.

For example, Section 1.A.19: Code Assignment and Clinical Criteria

“The assignment of a diagnosis code is based on the provider’s diagnostic statement that the condition exists. The provider’s statement that the patient has a particular condition is sufficient. Code assignment is not based on clinical criteria used by the provider to establish the diagnosis. If there is conflicting medical record documentation, query the provider.”

Finally, be sure to share this information with your Coding and Clinical Documentation Integrity staff as part of their preparedness plan for the October 1^st start of the 2024 CMS Fiscal Year.

Question:

There is confusion about coding an elevated troponin level. Should we use R77.8 per codebook or R79.89 per advice from Coding Clinic, Second Quarter 2019, pg. 6?

Answer:

The correct code assignment for an elevated troponin level is R77.8, Other Specified Abnormalities of Plasma Proteins. Coding Clinic, Second Quarter 2019, page 6 was superseded by the changes to the index that were effective with the discharges October 1, 2020. The ICD-10-CM Conventions and Coding Guidelines take precedence over Coding Clinic advice.

The OIG notes that this semiannual report is intended to keep the HHS Secretary and Congress fully and currently informed of OIG’s crucial findings and recommendations during the reporting period October 1, 2022 through March 31, 2023. https://oig.hhs.gov/reports-and-publications/archives/semiannual/2023/spring-sar-2023.pdf

Did You Know?

CMS recently published ICD-10-PCS and ICD-10-CM files for Fiscal Year 2024. Changes to the codes will be in effect for discharges occurring from October 1, 2023, through September 30, 2024.

ICD-10-PCS Files

The 2024 ICD-10-PCS files (https://www.cms.gov/medicare/icd-10/2024-icd-10-pcs) and FY 2024 ICD-10-PCS Guidelines for Coding and Reporting were published as of June 6, 2023.  

For FY 2024, there are 78 new codes and 5 deleted codes bringing the total number of ICD-10-PCS codes to 78,603. Note, with an increase of 40 codes for FY 2024, New Technology codes make up more than 50% of the new codes.

One change noted when compared to the FY 2023 PCS guidelines is in the Device General Guidelines section B6.1a. This section provides guidance that “if a device that is intended to remain after the procedure is completed requires removal before the end of the operative episode in which it was inserted, both the insertion and removal of the device should be coded.”

The FY 2023 guidelines included an example of when you would code both the insertion and the removal “(for example, the device size is inadequate or an event documented as a complication occurs).” The example has been removed from the FY 2024 guidelines.  

ICD-10-CM Files

The ICD-10-CM files (https://www.cms.gov/medicare/icd-10/2024-icd-10-cm) became available on June 16, 2023. For FY 2024, there are 395 new codes and 25 deleted codes bringing the number of ICD-10-CM codes to 74,044.

CMS noted in their announcement that the FY 2024 ICD-10-CM Coding Guidelines, FY 2024 Conversion Table and FY 2024 Present on Admission (POA) Exempt Code List will be posted when available.

Why it matters?

CMS notes, on the opening page of the 2024 ICD-10-PCS Official Guidelines for Coding and Reporting, “These guidelines have been developed to assist both the healthcare provider and the coder in identifying those procedures that are to be reported. The importance of consistent, complete documentation in the medical record cannot be overemphasized. Without such documentation accurate coding cannot be achieved.”

What can I do?

Share this information with coding and clinical documentation professions at your facility as you begin to prepare for the October 1, 2023, start of the CMS FY 2024.

Did You Know?

June is cataract awareness month and according to the National Eye Institute (https://www.nei.nih.gov/learn-about-eye-health/eye-conditions-and-diseases/cataracts), most cataracts are age-related, there are no early symptoms of cataracts and later symptoms includes blurry vision, colors that seem faded, sensitivity to light, trouble seeing at night and double vision.

A cataract is diagnosed by a dilated eye exam and the treatment is surgery. Cataract surgery is one of the most common operations in the United States. In fact, more than half of all Americans aged eighty or older either have cataracts or have had surgery to get rid of cataracts.

Why it Matters?

Being a high-volume surgery, means scrutiny by CMS and Medicare Contractors to assure documentation in the medical record supports medical necessity of the procedure.

Recovery Audit Contractors

RAC Issue 0002 cataract removal (https://www.cms.gov/Research-Statistics-Data-and-Systems/Monitoring-Programs/Medicare-FFS-Compliance-Programs/Recovery-Audit-Program/Approved-RAC-Topics-Items/0002-Cataract-Removal-Medical-Necessity-and-Documentation-Requirements) has been an approved complex review for procedures performed in the outpatient hospital setting and ambulatory surgery centers (ASCs) since February 1, 2017. RACs will review documentation to determine if cataract surgery meets Medicare coverage criteria, meets applicable coding guidelines, and/or is medically reasonable and necessary. Applicable National Coverage Determinations (NCDs), Local Coverage Determinations (LCDs), and Local Coverage Articles (LCAs) are included on this RAC issue webpage.

Comprehensive Error Rate Testing (CERT)

In the 2021 and 2022 CERT Medicare Fee-for-Service supplemental improper payment report, cataract removal and lens insertion is listed in Table D1: Top 20 Service Types with Highest Improper Payments: Part B (https://www.cms.gov/files/document/2021-medicare-fee-service-supplemental-improper-payment-data.pdf-0).

2021 CERT Report

The improper payment rate for this surgery was 12.7%. The CERT cited two types of errors, insufficient documentation, and incorrect coding, as being the cause of improper payments. Specifically,

the insufficient documentation project improper payment was $190,495,888 and the incorrect coding improper payment was $27,844,602.

2022 CERT Report

The improper payment rate for this surgery was 8.3%. Unlike 2021, 100% of the errors were due to insufficient documentation. The project improper payment rate was $146,067,233.

Medicare Administrative Contractors (MACs)

JE and JF MAC: Noridian

Cataract surgery has been a review target for Noridian MAC jurisdictions for a few years. Their most recent review findings were for claims with dates of service from January 1, 2023 through March 31, 2023.

Review results for jurisdictions were published April 12, 2023:

• Noridian JE error rate of 48.67%. https://med.noridianmedicare.com/web/jea/cert-review/mr/review-results
• Noridian JF error rate 45.88%. https://med.noridianmedicare.com/web/jfa/cert-review/mr/review-results

Noridian’s review results articles include top denial reasons, educational resources, and education regarding the medical necessity for cataract surgery.

Supplemental Medical Review Contractor (SMRC)

On February 16, 2022, the SMRC published a notification of their intent to review cataract surgeries performed in the physician office, outpatient hospital and specialty facility clinical access hospitals. In the background section of the notification, they note that “this type of surgery has been a topic of interest for the Office of Inspector General (OIG) for a number of years. The OIG looked into surgery in both the outpatient facility and ambulatory service center settings. CMS data reflects a potential vulnerability.”

The SMRC published review results on September 27, 2022 (https://noridiansmrc.com/completed-projects/01-302/). The error rate was 51%.

What Can You Do?

With so many entities focused on reviewing cataract surgery claims, moving forward providers should:

• Respond to ADRs in a timely manner,
• Become familiar with medical necessity indications and documentation requirements detailed in Medicare coverage documents (NCDs, LCDs, LCAs),
• Be aware of who is performing cataract surgery reviews,
• Read published review results to understand reasons for denials and ways to prevent future denials, and
• Ensure physicians performing these procedures are also aware of Medicare coverage requirements.
