I70.323 — Atherosclerosis of unspecified type of bypass graft(s) of the extremities with rest pain, bilateral legs
Is I70.323 billable?
Yes, but I70.323 is an unspecified code. I70.323 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, I70.323 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 I70.323 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from I70.3
The conditions below can never be reported together with I70.323 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- embolism or thrombus of bypass graft(s) of extremities (T82.8-)

How long has I70.323 existed?
I70.323 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
