Non-billable headerICD-10-CM

Z48.81 is a non-billable header ICD-10-CM code for encounter for surgical aftercare following surgery on specified body systems. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

aftercare for injury- code the injury with 7th character D
aftercare following surgery for neoplasm (Z48.3)

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.

Z48.81 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.

Z48.81 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
