Billable / specific codeICD-10-CMleft

I83.12 is a billable, specific ICD-10-CM code for varicose veins of left lower extremity with inflammation. It is valid for submission on a claim.

Excludes2 inherited from the categories above I83.12

Also inherited, and the opposite of Excludes1: these conditions are not part of I83.12, but a patient can have both, so you may code both.

Written on I83 Varicose veins of lower extremities

  • varicose veins complicating pregnancy (O22.0-)
  • varicose veins complicating the puerperium (O87.4)

Other codes that can never be billed with I83.12

These codes carry an Excludes1 note pointing at I83.12. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I83.12 alone.

  • I87.3Chronic venous hypertension (idiopathic)

Risk adjustment

I83.12 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

I83.12 is named in 15 Medicare coverage policies 15 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
