ICD-10 Code for Monoplegia
The ICD-10-CM code for monoplegia is G83.3 — Monoplegia, unspecified. This is the code the Alphabetic Index gives for monoplegia with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
G83.3 cannot be submitted on a claim. It is a header code, so a more specific code from the list below is required.
Which monoplegia code should you use?
The Alphabetic Index lists 21 codes under Monoplegia. 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.
