ICD-10 Code for Concussion
Also indexed as (brain) (cerebral) (current)
The ICD-10-CM code for concussion is S06.0X9 — Concussion with loss of consciousness of unspecified duration. This is the code the Alphabetic Index gives for concussion with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
S06.0X9 cannot be submitted on a claim. It is a header code, so a more specific code from the list below is required.
Which concussion code should you use?
The Alphabetic Index lists 11 codes under Concussion. 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.
