K60.4 — Rectal fistula
Is K60.4 billable?
No — K60.4 is a non-billable header code. K60.4 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 9 billable codes beneath K60.4.

Excludes1 — never code together
The conditions below can never be reported together with K60.4 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Code first
The underlying condition below must be sequenced before K60.4. K60.4 describes a manifestation and cannot be the principal or first-listed diagnosis.
