This code requires a 7th character
The appropriate 7th character is to be added to each code from category S43
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- rotator cuff syndrome (complete) (incomplete), not specified as traumatic (M75.1-)
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
- injury of tendon of rotator cuff (S46.0-)
Risk adjustment
S43.42 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 to one of these instead S43.42
