Z98 — Other postprocedural states

Non-billable headerICD-10-CM

Z98 is a non-billable header ICD-10-CM code for other postprocedural states. It cannot be billed on its own: choose one of the more specific child codes below.

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.

aftercare (Z43-Z49, Z51)
follow-up medical care (Z08-Z09)
Fontan related circulation (I27.84-)
postprocedural complication - see Alphabetical Index

Code to one of these instead Z98
