Q27.32

Q27.32 — Arteriovenous malformation of vessel of lower limb

Billable / specific codeICD-10-CMPOA exempt

Q27.32 is a billable, specific ICD-10-CM code for arteriovenous malformation of vessel of lower limb. It is valid for submission on a claim.

Excludes1 inherited from the categories above Q27.32

These are not written on Q27.32, but they bind it: a note on a category applies to every code beneath it. Billing Q27.32 with anything listed here is a denial.

Written on Q27.3 — Arteriovenous malformation (peripheral)

acquired arteriovenous aneurysm (I77.0)

Excludes2 inherited from the categories above Q27.32

Also inherited, and the opposite of Excludes1: these conditions are not part of Q27.32, but a patient can have both, so you may code both.

Written on Q27.3 — Arteriovenous malformation (peripheral)

arteriovenous malformation of cerebral vessels (Q28.2)
arteriovenous malformation of precerebral vessels (Q28.0)

Written on Q27 — Other congenital malformations of peripheral vascular system

anomalies of cerebral and precerebral vessels (Q28.0-Q28.3)
anomalies of coronary vessels (Q24.5)
anomalies of pulmonary artery (Q25.5-Q25.7)
congenital retinal aneurysm (Q14.1)
hemangioma and lymphangioma (D18.-)

Risk adjustment

Q27.32 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

Q27.32 is named in 14 Medicare coverage policies — 14 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
