Review the Action Required section below and ensure your team has completed all compliance steps before this date.
CMS Transmittal R13906OTN, Change Request (CR) 14537, published under Publication 100-20 on August 7, 2026, implements ICD-10 and other coding revisions to National Coverage Determinations (NCDs) with an implementation date of January 4, 2027. This is an administrative transmittal — not a Proposed Rule or LCD — meaning the changes are final and not subject to a comment period. The single most important compliance implication: any encoder, grouper, or claims scrubber that references NCD-linked ICD-10 code sets must be updated before the January 4, 2027 go-live date to avoid claim rejections on Medicare fee-for-service submissions.

Quick answers
Which specific NCDs and ICD-10 codes are revised under CR 14537?
The transmittal document itself (R13906OTN) does not enumerate the specific NCDs or ICD-10 codes affected. The complete list of revised codes and impacted NCDs is contained in the full CR 14537 documentation, which is available at the CMS source URL provided. Coders should download CR 14537 directly to identify which NCD-linked code sets apply to their service lines.
Does the January 4, 2027 implementation date apply to both professional and institutional claims?
Yes. NCDs govern Medicare coverage across provider types and apply to both 837P (professional) and 837I (institutional) claim formats. The shared system logic update under CR 14537 goes live January 4, 2027, and affects Medicare fee-for-service claims processing regardless of claim type. Both professional billing and hospital outpatient coding teams should confirm their respective scrubbers are updated before that date.
Is there a comment period or opportunity to request changes to the codes listed in CR 14537?
No. Transmittal R13906OTN is an administrative coding maintenance update issued under Publication 100-20 (One-Time Notifications). It is not a Proposed Rule or draft LCD, so there is no comment period. The changes are final as issued on August 7, 2026, with a mandatory implementation date of January 4, 2027.
