T81.718 — Complication of other artery following a procedure, not elsewhere classified
T81.718 is a non-billable header ICD-10-CM code for complication of other artery following a procedure, not elsewhere classified. 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 T81
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes1 inherited from the categories above T81.718
These are not written on T81.718, but they bind it: a note on a category applies to every code beneath it. Billing T81.718 with anything listed here is a denial.
Excludes2 inherited from the categories above T81.718
Also inherited, and the opposite of Excludes1: these conditions are not part of T81.718, but a patient can have both, so you may code both.
Written on T81.7 — Vascular complications following a procedure, not elsewhere classified
Written on T81 — Complications of procedures, not elsewhere classified
- complications following immunization (T88.0-T88.1)

- poisoning and toxic effects of drugs and chemicals (T36-T65 with fifth or sixth character 1-4)
Risk adjustment
T81.718 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.
How T81.718 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to T81.718.

Questions about T81.718
- Is T81.718 a billable ICD-10-CM code?
- No. T81.718 is a non-billable header code. Code to a higher level of specificity using one of its child codes.
- Where does T81.718 sit in the tabular list?
- Injury, poisoning and certain other consequences of external causes (S00-T88), in the block Complications of surgical and medical care, not elsewhere classified (T80-T88).
- What cannot be coded together with T81.718?
- T81.718 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above T81.718 (T81.7) and apply to it just the same.
