ICD-10 Z48
Non-Billable HeaderEncounter for other postprocedural aftercare
About ICD-10-CM Z48
ICD-10-CM code Z48 represents Encounter for other postprocedural aftercare. This is a non-billable header code in the Factors Influencing Health Status chapter (block Z48). The 2026 edition of ICD-10-CM Z48 became effective on October 1, 2025. Non-billable codes cannot be used as a primary or secondary diagnosis on a claim, use a more specific child code instead.
Type 1 Excludes
Pure excludes, these codes can never be coded together with Z48. The conditions are mutually exclusive (e.g., congenital vs acquired forms).
- encounter for follow-up examination after completed treatment (Z08-Z09)
- encounter for aftercare following injury - code to Injury, by site, with appropriate 7th character for subsequent encounter
Type 2 Excludes
Not included here, the excluded code is not part of Z48, but a patient may have both conditions at the same time. Both codes may be coded together when applicable.
- encounter for attention to artificial openings (Z43.-)
- encounter for fitting and adjustment of prosthetic and other devices (Z44-Z46)
