I70.669 — Atherosclerosis of nonbiological bypass graft(s) of the extremities with gangrene, unspecified extremity
Is I70.669 billable?
Yes, but I70.669 will trip a Medicare edit. I70.669 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists I70.669 under Medicare Code Editor edit 20, “Unspecified code” — meaning a code specifying laterality (right, left or bilateral) exists in the same family. On an inpatient claim this triggers the edit, because CMS holds that there are very limited circumstances in which laterality cannot be documented.

Which MS-DRGs does I70.669 group to?
I70.669 sits in MDC 05 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 299Peripheral Vascular Disorders with MCCmedical
- 300Peripheral Vascular Disorders with CCmedical
- 301Peripheral Vascular Disorders without CC/MCCmedical
As a secondary diagnosis, I70.669 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
