ICD-10 Code for Ureterocele
The ICD-10-CM code for ureterocele is N28.89 — Other specified disorders of kidney and ureter. This is the code the Alphabetic Index gives for ureterocele with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
N28.89 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which ureterocele code should you use?
The Alphabetic Index lists 3 codes under Ureterocele. Which one applies depends on the qualifier documented in the record — the type, site, cause, or associated condition. Find the qualifier below, then verify the code in the Tabular List before using it.
