Excludes1 — never code together — inherited from Z44
The conditions below can never be reported together with Z44.001 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- malfunction or other complications of device - see Alphabetical Index
- presence of prosthetic device (Z97.-)
Excludes2 — not included here — inherited from Z40-Z53
The conditions below are not part of Z44.001, but a patient may have both at the same time. When documentation supports it, Z44.001 and the excluded code may both be reported.
- follow-up examination for medical surveillance after treatment (Z08-Z09)
