HCC 20: Lung and Other Severe Cancers ICD-10-CM

CMS-HCC Category 20 (Lung and Other Severe Cancers) is a payment HCC in the V28 Medicare Advantage risk adjustment model. For payment year 2026 it adds a risk adjustment factor between 0.672 and 1.214 to a beneficiary's RAF score depending on the payment segment (1.136 for a community, non-dual, aged enrollee). 233 ICD-10-CM diagnosis codes map to HCC 20. A more severe related category (HCC 17, HCC 18, and HCC 19) supersedes it when both are reported.

RAF Weight by Payment Segment 7 segments

Payment Segment	Relative Factor
Community, non-dual, aged	1.136
Community, partial-benefit dual, aged	1.214
Community, full-benefit dual, aged	1.166
Community, non-dual, disabled	0.978
Community, partial-benefit dual, disabled	1.067
Community, full-benefit dual, disabled	1.173
Institutional	0.672

A beneficiary is scored in exactly one segment, set by Medicaid (dual) status, aged or disabled entitlement, and residence. Factors are relative weights, not dollar amounts; new-enrollee segments score on demographics only. In the hierarchy, HCC 17 (Cancer Metastatic to Lung, Liver, Brain, and Other Organs; Acute Myeloid Leukemia Except Promyelocytic), HCC 18 (Cancer Metastatic to Bone, Other and Unspecified Metastatic Cancer; Acute Leukemia Except Myeloid), and HCC 19 (Myelodysplastic Syndromes, Multiple Myeloma, and Other Cancers) supersede HCC 20 when reported together. HCC 20 in turn supersedes HCC 21 (Lymphoma and Other Cancers), HCC 22 (Bladder, Colorectal, and Other Cancers), and HCC 23 (Prostate, Breast, and Other Cancers and Tumors).

Questions About HCC 20

What is HCC 20 in the CMS-HCC model?

HCC 20 is CMS-HCC Category 20 (Lung and Other Severe Cancers) in the V28 risk adjustment model. It covers 233 ICD-10-CM diagnosis codes that raise a Medicare Advantage beneficiary's risk score when documented.

What is the RAF weight for HCC 20?

For payment year 2026, HCC 20 adds 1.136 to the RAF score of a community, non-dual, aged beneficiary. The published weights range from 0.672 to 1.214 across the seven payment segments shown above.

Which categories supersede HCC 20?

HCC 17 (Cancer Metastatic to Lung, Liver, Brain, and Other Organs; Acute Myeloid Leukemia Except Promyelocytic), HCC 18 (Cancer Metastatic to Bone, Other and Unspecified Metastatic Cancer; Acute Leukemia Except Myeloid), and HCC 19 (Myelodysplastic Syndromes, Multiple Myeloma, and Other Cancers) sit above HCC 20 in the hierarchy: when a beneficiary has diagnoses in both, only the more severe category is paid.
