ICD-10 Code for Amblyopia
Also indexed as (congenital) (ex anopsia) (partial) (suppression)
The ICD-10-CM code for amblyopia is H53.00 — Unspecified amblyopia. This is the code the Alphabetic Index gives for amblyopia with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
H53.00 cannot be submitted on a claim. It is a header code, so a more specific code from the list below is required.
Which amblyopia code should you use?
The Alphabetic Index lists 8 codes under Amblyopia. 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.
