T81.710A — Complication of mesenteric artery following a procedure, not elsewhere classified, initial encounter
T81.710A is a billable, specific ICD-10-CM code for complication of mesenteric artery following a procedure, not elsewhere classified, initial encounter. It is valid for submission on a claim.
7th character "A" — initial encounter
The appropriate 7th character is to be added to each code from category T81
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes1 inherited from the categories above T81.710A
These are not written on T81.710A, but they bind it: a note on a category applies to every code beneath it. Billing T81.710A with anything listed here is a denial.
Excludes2 inherited from the categories above T81.710A
Also inherited, and the opposite of Excludes1: these conditions are not part of T81.710A, but a patient can have both, so you may code both.

Risk adjustment
T81.710A 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.
Medicare coverage
T81.710A is named in 4 Medicare coverage policies — 4 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
