RTM Qualifying Diagnoses
for Pulmonology.

Code set. Every code on this page is drawn from the official ICD-10-CM ICD-10-CM FY2026 (valid 2025-10-01 through 2026-09-30) released by CDC/NCHS, and only codes flagged valid for submission are listed. ICD-10-CM is published by the federal government and is in the public domain, so the descriptions here are the official long descriptors reproduced verbatim rather than summarized. The next code set, ICD-10-CM FY2027 (valid from 2026-10-01), is already reflected in the change flags.

Eligibility is not a code list. CMS does not publish a list of ICD-10 codes that qualify a patient for RPM, CCM, PCM, BHI, or RTM. Eligibility turns on the condition and on documented medical necessity. The programs shown against each condition are CCN Health’s clinical assessment of which programs that condition can support, not a statement of CMS approval.

Risk adjustment. HCC labels and category assignments come from the CMS-HCC V28 model for the 2026 payment year. Risk adjustment depends on the full encounter record, not on a single code, and the flags here are a prompt to check specificity rather than a payment guarantee.
