Liver disorders in diseases classified elsewhere (K77) ICD-10-CM

Code First

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.

• 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
• schistosomiasis B65.0 B65.9

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

• 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
