About coding urine constituents abnormal
The ICD-10-CM code for urine constituents abnormal is R82.90 (Unspecified abnormal findings in urine). The official index lists 15 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R82.90.
Within R82.9, choose R82.90 (Unspecified abnormal findings in urine) only when documentation doesn't support a more specific option: other chromoabnormalities of urine (R82.91) and other abnormal findings in urine (R82.99).
Use an additional code to identify any retained foreign body, if applicable (Z18.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
