Did You Know?

In October 2021, CMS published Change Request (CR) 12471 (link). There were two stated purposes for this CR noted in the Summary of Changes:

• • Implement system changes needed to update the Shared System Maintainer (SSM) interface with the Java MCE to accept new MCE Edit 20-Unspecific Code Edit, and
• • Provide a mechanism to systematically bypass the new edit when a specific billing note is present in the claim remarks field to indicate the primary reason why laterality could not be determined

The effective date for this CR is April 1, 2022.

Why this Matters?

In ICD-10-CM there are unspecified codes for when documentation in the record does not provide detail needed to report a more specific code. “However, in the inpatient setting, there should generally be very limited and rare circumstances for which the laterality (right, left, bilateral) of a condition is unable to be documented and reported.”

Effective for claims with dates of service on or after April 1, 2022, new Code Edit 20- will be triggered when an unspecified diagnosis code currently designated as either a Complication or Comorbidity (CC) or Major Complication or Comorbidity (MCC), that includes other codes in that code subcategory that further specify the anatomic site, is entered.

You will find the complete list of 3,432 ICD-10-CM unspecified codes subject to this edit in table 6P.3a associated with the FY 2022 IPPS/LTCH Final Rule (link).

This edit is meant to signal providers that there is a more specific laterality code available to report. It will be the providers responsibility to determine if documentation in the medical record support’s a more specific code. “If, upon review, additional information to identify the laterality from the available medical record documentation by any other clinical provider is unable to be obtained or there is documentation in the record that the physician is clinically unable to determine the laterality because of the nature of the disease/condition, then the provider must enter that information in the remarks section.

Mechanism to Bypass new MCE Edit 20-

The provider may enter a remark:

• • Either “UNABLE TO DET LAT 1” to indicate that they are unable to obtain additional information to specify laterality, or
• • “UNABLE TO DET LAT 2” to indicate the physician is clinically unable to determine laterality

However, “if there is no language entered into the remarks section as to the availability of additional information to specific laterality and the provider submits the claim for processing, the claim would be returned to the provider.”

“0 or 1 day” Length of Stay Claims

After reading this CR, my first thought was, how often are one of these codes being included on a claim. To find the answer, I turned to our sister company, RealTime Medicare Data (RTMD). Following are the numbers for Medicare Fee-for-Service paid claims data with dates of service from October 1, 2020, through August 31, 2021, available in RTMD’s footprint:

• • 57,951 claims included one of the unspecified codes in Table 6P.3a of the FY 2022 IPPS/LTCH Final Rule,
• • The paid claims total for this set of claims was $1,010,178,584.54, and
• • The top five states by claims volume included:
• o California: 5,926 claims - $135,738,052.81
• o Texas: 5,872 claims - $104,453,156.02
• o New York: 3,290 claims - $70,001,125.23
• o Pennsylvania: 3,192 claims - $48,281,839.67
• o Illinois: 2,750 claims - $41,821,442.35

What Can You Do?

This is not a large volume of claims in the world of Medicare Fee-for-Service Inpatient paid claims. However, just over $1 billion in paid claims is a significant amount of money. With a little over a month to prepare, you should make sure that CR 12471 and related MLN Matters article MM12471(link) are shared with key stakeholders at your facility (i.e., Billing, Coding, Clinical Documentation Integrity Specialists). You should also work with your IT department to anticipate the potential volume of claims that will be impacted by the new Code Edit 20-.
