Non-billable headerICD-10-CMleft

T81.59 is a non-billable header ICD-10-CM code for other complications of foreign body accidentally left in body following procedure. 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

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.

obstruction or perforation due to prosthetic devices and implants intentionally left in body (T82.0-T82.5, T83.0-T83.4, T83.7, T84.0-T84.4, T85.0-T85.6)

Excludes2 inherited from the categories above T81.59

Also inherited, and the opposite of Excludes1: these conditions are not part of T81.59, but a patient can have both, so you may code both.

Risk adjustment

T81.59 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.

T81.59 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
