ICD-10 Code for Proteinuria
The ICD-10-CM code for proteinuria is R80.9 — Proteinuria, unspecified. This is the code the Alphabetic Index gives for proteinuria with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
R80.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which proteinuria code should you use?
The Alphabetic Index lists 22 codes under Proteinuria. 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.
