What is ICD-10 code G62.1?

G62.1 is the ICD-10-CM diagnosis code for Alcoholic polyneuropathy. Nerve damage affecting multiple nerves caused by chronic alcohol consumption, leading to weakness and numbness typically in the legs and feet. It belongs to the ICD-10-CM chapter for diseases of the nervous system (g00-g99). G62.1 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. G62.1 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. G62.1 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. G62.1 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 G62.1 map to under V28?

G62.1 has no payable CMS-HCC V28 mapping in the final FY2026 CMS file.

What RAF reference is published for G62.1?

G62.1 has no V28 reference coefficient because the final FY2026 source verifies no payable V28 mapping.

What is the V28 vs V24 difference for G62.1?

G62.1 has verified no payable V28 mapping in the final FY2026 source. Select a historical effective period before making any V24 comparison.

What documentation supports G62.1?

Link this diagnosis to alcohol use disorder codes (F10.x) for complete clinical documentation Document the patient's alcohol consumption history and duration in the medical record G62.1 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.

Buddy Documentation Tip

HCC Buddy guidance

Documented history of chronic alcohol use or alcohol use disorder

Clinical presentation: symmetric sensory-motor polyneuropathy, typically distal-predominant

Nerve conduction studies or electromyography findings supporting polyneuropathy diagnosis

Link between alcohol use and the neuropathy explicitly stated by provider

MEAT Support

HCC Buddy guidance

Documented history of chronic alcohol use or alcohol use disorder

Clinical presentation: symmetric sensory-motor polyneuropathy, typically distal-predominant

Nerve conduction studies or electromyography findings supporting polyneuropathy diagnosis

Link between alcohol use and the neuropathy explicitly stated by provider

Audit Caution

HCC Buddy guidance

Failing to also code the underlying alcohol use disorder (F10.x series) which provides important clinical context

Coding as unspecified polyneuropathy when the provider documents alcohol as the causative factor

Not querying the provider when a patient has both diabetes and chronic alcohol use to determine the primary cause of neuropathy

Assuming all neuropathy in an alcoholic patient is alcoholic neuropathy — other causes should be ruled out first

Common Mistakes

HCC Buddy guidance

G62.0 — Drug-induced polyneuropathy is for prescription medication-caused neuropathy, not alcohol

G62.2 — Polyneuropathy due to other toxic agents is for non-alcohol toxic exposures

E11.42 — Diabetic polyneuropathy may coexist with alcoholic neuropathy; both should be coded if present

G62.9 — Polyneuropathy, unspecified should not be used when alcohol etiology is documented

Is G62.1 an HCC code?

G62.1 is not in the CMS-HCC V28 or V24 community payment model. G62.1 has a separate mapping under the CMS-HCC ESRD model (HCC 75 (Myasthenia Gravis/Myoneural Disorders and Guillain-Barre Syndrome/Inflammatory and Toxic Neuropathy)) and the Part D RxHCC model (HCC 158 (Inflammatory and Toxic Neuropathy)); the applicable result needs member context. G62.1 also appears in the HHS-HCC commercial risk model (HCC 115 (HHS-HCC 115 adult, RAF varies by metal level)), which is a commercial market model rather than a Medicare Advantage payment mapping.

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 review for G62.1

For G62.1, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule.

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

What This Code Means

G62.1 is the ICD-10-CM diagnosis code for alcoholic polyneuropathy. Nerve damage affecting multiple nerves caused by chronic alcohol consumption, leading to weakness and numbness typically in the legs and feet. G62.1 sits in the ICD-10-CM chapter for diseases of the nervous system (g00-g99), within the section covering polyneuropathies and other disorders of the peripheral nervous system (g60-g65).

G62.1 has no mapping under the CMS-HCC V28 or V24 community payment models. G62.1 has a separate mapping under the CMS-HCC ESRD model (HCC 75 (Myasthenia Gravis/Myoneural Disorders and Guillain-Barre Syndrome/Inflammatory and Toxic Neuropathy)) and the Part D RxHCC model (HCC 158 (Inflammatory and Toxic Neuropathy)); the applicable result needs member context. G62.1 also appears in the HHS-HCC commercial risk model (HCC 115 (HHS-HCC 115 adult, RAF varies by metal level)), which is a commercial market model rather than a Medicare Advantage payment mapping. Do not assign V28 risk adjustment value from this page; verify the applicable model and payment year before using this code for risk adjustment.

Link this diagnosis to alcohol use disorder codes (F10.x) for complete clinical documentation.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for G62.1 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Link this diagnosis to alcohol use disorder codes (F10.x) for complete clinical documentation
•Document the patient's alcohol consumption history and duration in the medical record

Clinical Significance

Alcoholic polyneuropathy is a direct complication of chronic alcohol use disorder, reflecting nerve damage from prolonged toxic alcohol exposure and nutritional deficiencies. It indicates a patient with dual complexity — both a substance use disorder and significant neurological impairment. Accurate capture is important for reflecting the true care burden and coordinating addiction treatment with neurological management.

Documentation Requirements

✓Documented history of chronic alcohol use or alcohol use disorder
✓Clinical presentation: symmetric sensory-motor polyneuropathy, typically distal-predominant
✓Nerve conduction studies or electromyography findings supporting polyneuropathy diagnosis
✓Link between alcohol use and the neuropathy explicitly stated by provider
✓Associated alcohol use disorder code (F10.x) documented
✓Nutritional status assessment including thiamine/B-vitamin levels when available

Commonly Confused Codes

•G62.0: Drug-induced polyneuropathy is for prescription medication-caused neuropathy, not alcohol
•G62.2: Polyneuropathy due to other toxic agents is for non-alcohol toxic exposures
•E11.42: Diabetic polyneuropathy may coexist with alcoholic neuropathy; both should be coded if present
•G62.9: Polyneuropathy, unspecified should not be used when alcohol etiology is documented
