K72.91 — Hepatic failure, unspecified with coma
Is K72.91 billable?
Yes, but K72.91 is an unspecified code. K72.91 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, K72.91 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting K72.91 — the more specific alternatives are listed below.

Which MS-DRGs does K72.91 group to?
K72.91 sits in MDC 07 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 441Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis with MCCmedical
- 442Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis with CCmedical
- 443Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis without CC/MCCmedical
As a secondary diagnosis, K72.91 is a major complication or comorbidity (MCC), which can move a stay into a higher-paying DRG.
