Non-billable headerICD-10-CM

This code requires a 7th character
The appropriate 7th character is to be added to each code from category S16
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
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.
- sprain of joint or ligament at neck level (S13.9)
Code also
Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.
- any associated open wound (S11.-)
Risk adjustment
S16 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 S16
4 child codes. Green means billable.
