G89.21 — Chronic pain due to trauma
G89.21 is a billable, specific ICD-10-CM code for chronic pain due to trauma. It is valid for submission on a claim.
Risk adjustment
G89.21 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

G89.21 is named in 11 Medicare coverage policies — 6 listing it as supporting medical necessity, and 5 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
