ICD-10 Code for Hemiplegia

The ICD-10-CM code for hemiplegia is G81.9 — Hemiplegia, unspecified. This is the code the Alphabetic Index gives for hemiplegia with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).

Not billable

G81.9 cannot be submitted on a claim. It is a header code, so a more specific code from the list below is required.

Which hemiplegia code should you use?

The Alphabetic Index lists 19 codes under Hemiplegia. 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.
