Excludes1 — never code together
The conditions below can never be reported together with Z42 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- encounter for cosmetic plastic surgery (Z41.1)
- encounter for plastic surgery for treatment of current injury - code to relevent injury
Excludes2 — not included here — inherited from Z40-Z53
The conditions below are not part of Z42, but a patient may have both at the same time. When documentation supports it, Z42 and the excluded code may both be reported.
- follow-up examination for medical surveillance after treatment (Z08-Z09)
