Is S15.001 a billable ICD-10-CM code?

No. S15.001 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does S15.001 sit in the tabular list?

Injury, poisoning and certain other consequences of external causes (S00-T88), in the block Injuries to the neck (S10-S19).

What cannot be coded together with S15.001?

S15.001 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above S15.001 (S15.0) and apply to it just the same.

Non-billable headerICD-10-CMright

S15.001 is a non-billable header ICD-10-CM code for unspecified injury of right carotid artery. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

This code requires a 7th character

The appropriate 7th character is to be added to each code from category S15

A: initial encounter
D: subsequent encounter
S: sequela

Excludes1 inherited from the categories above S15.001

These are not written on S15.001, but they bind it: a note on a category applies to every code beneath it. Billing S15.001 with anything listed here is a denial.

Written on S15.0 — Injury of carotid artery of neck

injury of internal carotid artery, intracranial portion (S06.8)

Other codes that can never be billed with S15.001

These codes carry an Excludes1 note pointing at S15.001. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S15.001 alone.

S09.0XXAInjury of blood vessels of head, not elsewhere classified, initial encounter
S09.0XXDInjury of blood vessels of head, not elsewhere classified, subsequent encounter

Risk adjustment

S15.001 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.

Code history

S15.001 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
