Inclusion terms
Alternative wording in documentation that is classified to Z85.520.
- Conditions classifiable to C7A.093
Excludes1 — never code together — inherited from Z85.52
The conditions below can never be reported together with Z85.520 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- personal history of malignant neoplasm of renal pelvis (Z85.53)
Code first — inherited from Z85
The underlying condition below must be sequenced before Z85.520. Z85.520 describes a manifestation and cannot be the principal or first-listed diagnosis.
- any follow-up examination after treatment of malignant neoplasm (Z08)
Use additional code — inherited from Z85
Report an additional code alongside Z85.520 to fully describe the condition. Z85.520 is sequenced first.
Excludes2 — not included here — inherited from Z85
The conditions below are not part of Z85.520, but a patient may have both at the same time. When documentation supports it, Z85.520 and the excluded code may both be reported.
Code also — inherited from Z77-Z99
Two codes may be needed to describe the condition fully. Whether Z85.520 is sequenced first depends on the reason for the encounter.
- any follow-up examination (Z08-Z09)
