Post-Concussion Syndrome ICD-10 Codes: A Quick Reference
The ICD-10-CM code for post-concussion syndrome is F07.81 — "Postconcussional syndrome." Below is a quick, practical reference for coding concussion care, since PCS coding almost always travels with an underlying injury code.
F07.81 — Postconcussional syndrome
Use F07.81 for persistent post-concussive symptoms (headache, dizziness, cognitive complaints, irritability, sleep disturbance) following head trauma. Two practical notes:
- F07.81 describes the syndrome; code the original injury (S06.0X-) with the appropriate 7th character where documentation supports it.
- Coding guidance excludes assigning F07.81 with a current (initial-encounter) concussion injury — it's a sequela-phase diagnosis. When symptoms persist after the acute phase, F07.81 with the injury code carrying a "S" (sequela) 7th character is the common pattern.
Concussion injury codes: S06.0X series
- S06.0X0 — Concussion without loss of consciousness
- S06.0X1 — Concussion with LOC ≤ 30 minutes
- S06.0X9 — Concussion with LOC of unspecified duration
Each requires a 7th character: A (initial encounter), D (subsequent encounter), S (sequela) — e.g., S06.0X0A for a first evaluation, S06.0X0S when treating late effects.
Frequently paired symptom codes
- G44.30-/G44.31- — Post-traumatic headache (unspecified / acute)
- R42 — Dizziness; H81.1- — BPPV when identified
- H51.11 — Convergence insufficiency
- R41.840 — Attention/concentration deficit; F51.01 — Insomnia-type codes as documented
Documentation tips that survive audits
Tie each therapy order (vestibular PT, vision therapy, exertion testing, neuropsychological testing) to a specific coded symptom; record the injury date and mechanism at every encounter; and update the 7th character as care moves from acute to sequela phase. Always confirm codes against the current ICD-10-CM release and payer policy — this reference is educational, not billing advice.
