About coding polyuria
The ICD-10-CM code for polyuria is R35.89 (Other polyuria). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R35.89.
Within R35.8, choose R35.89 (Other polyuria) only when documentation doesn't support a more specific option: nocturnal polyuria (R35.81).
Code first , if applicable, any causal condition, such as: enlarged prostate (N40.1).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
