Excludes1 — never code together — inherited from Z51
The conditions below can never be reported together with Z51.5 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- follow-up examination after treatment (Z08-Z09)
Excludes2 — not included here — inherited from Z40-Z53
The conditions below are not part of Z51.5, but a patient may have both at the same time. When documentation supports it, Z51.5 and the excluded code may both be reported.
- follow-up examination for medical surveillance after treatment (Z08-Z09)
Code also — inherited from Z51
Two codes may be needed to describe the condition fully. Whether Z51.5 is sequenced first depends on the reason for the encounter.
