ICD-10 Code for Deafness
Also indexed as (acquired) (complete) (hereditary) (partial)
The ICD-10-CM code for deafness is H91.9 — Unspecified hearing loss. This is the code the Alphabetic Index gives for deafness with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
H91.9 cannot be submitted on a claim. It is a header code, so a more specific code from the list below is required.
Which deafness code should you use?
The Alphabetic Index lists 21 codes under Deafness. 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.
