ICD-10 Code for Nephrosis
Also indexed as (Epstein's) (syndrome) (congenital)
The ICD-10-CM code for nephrosis is N04.9 — Nephrotic syndrome with unspecified morphologic changes. This is the code the Alphabetic Index gives for nephrosis with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
N04.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which nephrosis code should you use?
The Alphabetic Index lists 15 codes under Nephrosis, nephrotic. 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.
