About I70.293
I70.293 is the ICD-10-CM diagnosis code for other atherosclerosis of native arteries of extremities, bilateral legs. It belongs to category I70 (atherosclerosis), block I70-I79 (diseases of arteries, arterioles and capillaries) and chapter 9 (diseases of the circulatory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within I70.29 (other atherosclerosis of native arteries of extremities), I70.293 is specifically for other atherosclerosis of native arteries of extremities, bilateral legs. Related codes cover right leg (I70.291), left leg (I70.292), other extremity (I70.298) and unspecified extremity (I70.299).
Use an additional code to identify: exposure to environmental tobacco smoke (Z77.22), history of tobacco dependence (Z87.891), occupational exposure to environmental tobacco smoke (Z57.31), tobacco dependence (F17.-) and tobacco use (Z72.0).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 299 (Peripheral Vascular Disorders with MCC, relative weight 1.5842), DRG 300 (Peripheral Vascular Disorders with CC, relative weight 1.0464) and DRG 301 (Peripheral Vascular Disorders without CC/MCC, relative weight 0.7133), in MDC 05 (Diseases and Disorders of the Circulatory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
The Medicare Code Editor expects this diagnosis only for patients age 15 through 124.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 440.29 (other atherosclerosis of native arteries of the extremities).
