K77 — Liver disorders in diseases classified elsewhere

Billable / specific codeICD-10-CM

K77 is a billable, specific ICD-10-CM code for liver disorders in diseases classified elsewhere. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

alcoholic hepatitis (K70.1-)
alcoholic liver disease (K70.-)
cytomegaloviral hepatitis (B25.1)
herpesviral [herpes simplex] hepatitis (B00.81)
mumps hepatitis (B26.81)
sarcoidosis with liver disease (D86.89)
secondary syphilis with liver disease (A51.45)
syphilis (late) with liver disease (A52.74)
toxoplasmosis (acquired) hepatitis (B58.1)
tuberculosis with liver disease (A18.83)

Code first

The underlying condition must be sequenced before this code.

underlying disease, such as:
amyloidosis (E85.-)
congenital syphilis (A50.0, A50.5)
congenital toxoplasmosis (P37.1)
infectious mononucleosis with liver disease (B27.0-B27.9 with fifth character 9)
schistosomiasis (B65.0-B65.9)

Risk adjustment

K77 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Medicare coverage

K77 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
