What This Code Means

N99.52 is the ICD-10-CM diagnosis code for complication of incontinent external stoma of urinary tract. N99.52 sits in the ICD-10-CM chapter for diseases of the genitourinary system (n00-n99), within the section covering intraoperative and postprocedural complications and disorders of genitourinary system, not elsewhere classified (n99).

Header codes like N99.52 cannot be reported on claims directly; they organize child codes that share clinical context. Coders should select the billable child code that matches the documented presentation and then verify its current source-backed HCC mapping. Do not infer a child code or risk adjustment value from the header alone.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for N99.52 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
