P15.2 — Sternomastoid injury due to birth injury
P15.2 is a billable, specific ICD-10-CM code for sternomastoid injury due to birth injury. It is valid for submission on a claim.
Other codes that can never be billed with P15.2
These codes carry an Excludes1 note pointing at P15.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P15.2 alone.
- M43.6Torticollis
Risk adjustment
P15.2 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.
Medicare coverage
P15.2 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How P15.2 is indexed
