- Chronic Condition
K72.11 is a billable ICD-10-CM diagnosis code for chronic hepatic failure with coma. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 441 through 443. As a secondary diagnosis, it counts as a major complication or comorbidity (MCC) and places an inpatient stay in the highest severity level of its MS-DRG family. It does not count, however, when the principal diagnosis is one of 6 closely related codes. Coders also document this condition as hepatic coma due to chronic hepatic failure. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Coma; stupor; and brain damage and Hepatic failure.
For Medicare Advantage risk adjustment, K72.11 maps to CMS-HCC Category 63 (Chronic Liver Failure/End-Stage Liver Disorders) under the V28 model, adding a risk factor of about 0.962 for a community, non-dual, aged beneficiary in payment year 2027.

Questions About K72.11Overview
What is the ICD-10 code for chronic hepatic failure with coma?
The ICD-10-CM code for chronic hepatic failure with coma is K72.11 (sometimes written as K7211). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is K72.11 (Chronic hepatic failure) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report chronic hepatic failure with coma on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does K72.11 group to?
When chronic hepatic failure with coma is the principal diagnosis on an inpatient stay, it groups to MS-DRG 442, 441, 443, with relative weights from 0.6890 to 1.8226 depending on complications. Higher weights mean higher Medicare reimbursement.
Is K72.11 a CC or MCC?
CMS lists K72.11 as an MCC (major complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it places the inpatient stay in the highest-weighted DRG of its severity family. It does not count when the principal diagnosis is one of the 6 closely related codes in its exclusion list.
Can K72.11 be reported with K70.4?
Not as a rule. The Excludes1 note at K72, which applies to K72.11, lists "alcoholic hepatic failure (K70.4)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
What HCC is K72.11?
K72.11 (chronic hepatic failure with coma) maps to CMS-HCC Category 63 (Chronic Liver Failure/End-Stage Liver Disorders), commonly written as HCC 63, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 27 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. It does not map to any RxHCC in the Part D prescription drug model.
Does K72.11 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, K72.11 adds a risk adjustment factor of about 0.962 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.861 to 1.209 depending on the payment segment). A more severe related category (HCC 62) supersedes it when both are reported. See the full factor table on the HCC 63 category page.
