Abnormal serum enzyme level, unspecified
ValidICD-10-CM diagnosis code.
Valid for claims with a date of service in the current code year.
What has happened to this code
Every change the publisher made, from 2007 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

Official coding rules
Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.
Inherited from the R70-R79 section Abnormal findings on examination of blood, without diagnosis (R70-R79)
Excludes2 - not included here
- abnormal findings on antenatal screening of mother (O28.-)
- abnormalities of lipids (E78.-)
- abnormalities of platelets and thrombocytes (D69.-)
- abnormalities of white blood cells classified elsewhere (D70-D72)
- coagulation hemorrhagic disorders (D65-D68)
- diagnostic abnormal findings classified elsewhere - see Alphabetical Index
- hemorrhagic and hematological disorders of newborn (P50-P61)
