How is K60.529 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to K60.529. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Fistula › anorectal › complex (cutaneous)
Excludes1 — never code together — inherited from K60.5
The conditions below can never be reported together with K60.529 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- congenital fistula (Q43.6)
Code first — inherited from K60.5
The underlying condition below must be sequenced before K60.529. K60.529 describes a manifestation and cannot be the principal or first-listed diagnosis.
Excludes2 — not included here — inherited from Chapter 11
The conditions below are not part of K60.529, but a patient may have both at the same time. When documentation supports it, K60.529 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
