This code requires a 7th character
The appropriate 7th character is to be added to each code from category S13

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.

Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.
Risk adjustment
S13.1 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.
