I73.89 — Other specified peripheral vascular diseases
Is I73.89 billable?
Yes, but I73.89 is an unspecified code. I73.89 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, I73.89 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting I73.89 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from I73.8
The conditions below can never be reported together with I73.89 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- diabetic (peripheral) angiopathy (E08-E13 with .51-.52)
Excludes2 — not included here — inherited from Chapter 9
The conditions below are not part of I73.89, but a patient may have both at the same time. When documentation supports it, I73.89 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)
