I70.319Atherosclerosis of unspecified type of bypass graft(s) of the extremities with intermittent claudication, unspecified extremity

Billable / specific codeICD-10-CM

I70.319 is a billable, specific ICD-10-CM code for atherosclerosis of unspecified type of bypass graft(s) of the extremities with intermittent claudication, unspecified extremity. It is valid for submission on a claim.

Excludes1 inherited from the categories above I70.319

These are not written on I70.319, but they bind it: a note on a category applies to every code beneath it. Billing I70.319 with anything listed here is a denial.

Written on I70.3 Atherosclerosis of unspecified type of bypass graft(s) of the extremities

  • embolism or thrombus of bypass graft(s) of extremities (T82.8-)

Excludes2 inherited from the categories above I70.319

Also inherited, and the opposite of Excludes1: these conditions are not part of I70.319, but a patient can have both, so you may code both.

Written on I70 Atherosclerosis

  • arteriosclerotic cardiovascular disease (I25.1-)
  • arteriosclerotic heart disease (I25.1-)
  • atheroembolism (I75.-)
  • cerebral atherosclerosis (I67.2)
  • coronary atherosclerosis (I25.1-)
  • mesenteric atherosclerosis (K55.1)
  • precerebral atherosclerosis (I67.2)
  • primary pulmonary atherosclerosis (I27.0)

Other codes that can never be billed with I70.319

These codes carry an Excludes1 note pointing at I70.319. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I70.319 alone.

  • I77.6Arteritis, unspecified

Risk adjustment

I70.319 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Medicare coverage

I70.319 is named in 1 Medicare coverage policy 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
