What is the ICD-10 code for PVD?

The ICD-10-CM code for PVD (peripheral vascular disease, unspecified) is I73.9. I73.9 is a billable diagnosis code in the FY2026 ICD-10-CM code set used on Medicare Advantage and commercial claims. Coders also write it as PAD.

What is ICD-10 code I73.9?

I73.9 is the ICD-10-CM diagnosis code for Peripheral vascular disease, unspecified. This code describes a disease affecting the blood vessels outside the heart and brain, but the specific type or location is not documented. It indicates poor circulation in the arms, legs, or other peripheral areas. I73.9 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. I73.9 is part of the FY2026 ICD-10-CM code set published by the CMS National Center for Health Statistics and used on Medicare, Medicaid, and commercial claims in the United States.

Yes. I73.9 is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. I73.9 is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

Which HCC does I73.9 map to under V28?

I73.9 has no payable CMS-HCC V28 mapping in the final FY2026 CMS file.

What RAF reference is published for I73.9?

I73.9 has no V28 reference coefficient because the final FY2026 source verifies no payable V28 mapping.

What is the V28 vs V24 difference for I73.9?

I73.9 has verified no payable V28 mapping in the final FY2026 source. Select a historical effective period before making any V24 comparison.

What documentation supports I73.9?

Peripheral vascular disease, unspecified, PVD without specification of atherosclerotic vs other etiology, or without specific vessel or symptom detail. The least specific PVD code. Prefer I70.2xx when atherosclerosis is documented. I73.9 is a fallback for vasospastic or other non-atherosclerotic PVD, or when etiology is truly unclear. I73.9 does not map to a V28 payment HCC. Query for atherosclerotic etiology whenever possible, but note the I70.2 family only risk-adjusts when rest pain (HCC 264) or ulceration/gangrene (HCC 263) is documented; claudication and unspecified atherosclerosis carry no V28 HCC either. I73.9 is not a CMS-HCC V28 payment code in the verified current source, so MEAT is not the payment hook. Documentation still has to support the diagnosis if you report it.

Using this unspecified code when documentation supports a more specific diagnosis like atherosclerosis of extremity arteries

Confusing peripheral vascular disease (arterial) with peripheral venous disease — different code categories

Not reviewing vascular lab results that could provide the specificity needed for a more precise code

Accepting 'PVD' on the problem list without querying for specificity about the type and affected extremities

Common Mistakes

HCC Buddy guidance

I70.2xx — Atherosclerosis of native arteries of extremities: more specific atherosclerotic disease codes with severity staging

I73.89 — Other specified peripheral vascular diseases: use when a named condition is documented

I87.2 — Venous insufficiency (chronic)(peripheral): venous disease, not arterial

I73.1 — Thromboangiitis obliterans: specific inflammatory vascular disease

Is I73.9 an HCC code?

I73.9 is not in the CMS-HCC V28 or V24 community payment model. I73.9 has a separate mapping under the CMS-HCC ESRD model (HCC 108 (Vascular Disease)); the applicable result needs member context.

Code: I73.9
Description: Peripheral vascular disease, unspecified
HCC (V28): No CMS-HCC V28 mapping
RAF reference coefficient: —
Billable: Yes
Payment year: 2026

HCC Category Mapping

ESRDHCC 108, Vascular Disease

Not separately weighted

These are source-labeled model coefficients, not member totals. A category may still be removed by hierarchy or model cleanup rules. Weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member context, hierarchy and cleanup rules, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains available for historical review.

MEAT Criteria for I73.9

For I73.9 to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically, it has to be re-documented and supported each calendar year.

MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
EEvaluate: test results, medication response, or physical findings reviewed by the provider
AAssess: explicit mention in the assessment or plan with acknowledgment of status
TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis

Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed I73.9 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

I73.9 is the ICD-10-CM diagnosis code for peripheral vascular disease, unspecified. This code describes a disease affecting the blood vessels outside the heart and brain, but the specific type or location is not documented. It indicates poor circulation in the arms, legs, or other peripheral areas. I73.9 sits in the ICD-10-CM chapter for diseases of the circulatory system (i00-i99), within the section covering diseases of arteries, arterioles and capillaries (i70-i79).

I73.9 has no mapping under the CMS-HCC V28 or V24 community payment models. I73.9 has a separate mapping under the CMS-HCC ESRD model (HCC 108 (Vascular Disease)); the applicable result needs member context. Do not assign V28 risk adjustment value from this page; verify the applicable model and payment year before using this code for risk adjustment.

Peripheral vascular disease, unspecified, PVD without specification of atherosclerotic vs other etiology, or without specific vessel or symptom detail. The least specific PVD code.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for I73.9 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Peripheral vascular disease, unspecified, PVD without specification of atherosclerotic vs other etiology, or without specific vessel or symptom detail. The least specific PVD code.
•Prefer I70.2xx when atherosclerosis is documented. I73.9 is a fallback for vasospastic or other non-atherosclerotic PVD, or when etiology is truly unclear.
•Query for atherosclerotic etiology whenever possible, but note the I70.2 family only risk-adjusts when rest pain (HCC 264) or ulceration/gangrene (HCC 263) is documented; claudication and unspecified atherosclerosis carry no V28 HCC either.

Clinical Significance

Peripheral vascular disease, unspecified, is a commonly used but nonspecific code that indicates arterial insufficiency of the extremities without further characterization. While it captures vascular disease for risk adjustment, it represents a missed opportunity for more precise coding. The prevalence of this condition in elderly populations makes it a frequently encountered diagnosis in risk adjustment reviews.

Documentation Requirements

✓Documentation of peripheral vascular disease diagnosis
✓Clinical findings (diminished pulses, claudication, rest pain, skin changes)
✓Vascular studies if performed (ankle-brachial index, duplex ultrasound)
✓Affected extremities
✓Severity assessment (claudication distance, Fontaine or Rutherford classification)
✓Treatment plan (exercise, pharmacotherapy, revascularization consideration)
