About coding fatty liver
The ICD-10-CM code for fatty liver is K76.0 (Fatty (change of) liver, not elsewhere classified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K76.0.
It is also searched as NAFLD, hepatic steatosis.
Within K76 (other diseases of liver), K76.0 is specifically for fatty (change of) liver, not elsewhere classified. Related codes cover chronic passive congestion of liver (K76.1), central hemorrhagic necrosis of liver (K76.2), infarction of liver (K76.3), Peliosis hepatis (K76.4), hepatic veno-occlusive disease (K76.5), portal hypertension (K76.6), hepatorenal syndrome (K76.7), other specified diseases of liver (K76.8) and 1 more.
Don't report K76.0 together with the conditions in its Excludes1 note: nonalcoholic steatohepatitis (NASH) (K75.81).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
