S46.0 — Injury of muscle(s) and tendon(s) of the rotator cuff of shoulder
S46.0 is a non-billable header ICD-10-CM code for injury of muscle(s) and tendon(s) of the rotator cuff of shoulder. 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 S46
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Other codes that can never be billed with S46.0
These codes carry an Excludes1 note pointing at S46.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S46.0 alone.
- M75.1Rotator cuff tear or rupture, not specified as traumatic
Risk adjustment
S46.0 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.
