Is G62.0 an HCC code?
Yes. G62.0 maps to Myasthenia Gravis/Myoneural Disorders and Guillain-Barre Syndrome/Inflammatory and Toxic Neuropathy under the V24 model but is not retained in V28.

HCC Category Mapping
Each model's RAF is its CMS base weight for that model's standard population, so 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 segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.

MEAT Criteria for G62.0
For G62.0 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 G62.0 during that encounter, not just copy-forwarded from a problem list.

What This Code Means
G62.0 is the ICD-10-CM diagnosis code for drug-induced polyneuropathy. Nerve damage affecting multiple nerves caused by medications or drugs, resulting in weakness, numbness, or pain in the extremities. G62.0 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).
Under the older CMS-HCC V24 model, G62.0 maps to Myasthenia Gravis/Myoneural Disorders and Guillain-Barre Syndrome/Inflammatory and Toxic Neuropathy (HCC 75) with a community, non-dual, aged base RAF weight of 0.472. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.
Always document the specific drug or medication causing the polyneuropathy. Because G62.0 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for G62.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
Clinical Significance
Drug-induced polyneuropathy is a significant adverse drug reaction that indicates nerve damage from medication exposure, commonly seen with chemotherapy agents, antiretrovirals, and certain antibiotics. It reflects the complexity of managing patients on potentially neurotoxic medications and may indicate ongoing cancer or infectious disease treatment. Accurate capture is essential for risk adjustment and adverse event surveillance.
Documentation Requirements
- ✓Identification of the specific causative drug or medication
- ✓Temporal relationship between drug exposure and neuropathy onset
- ✓Clinical findings: type and distribution of neuropathy symptoms
- ✓Nerve conduction studies or electromyography supporting the diagnosis
- ✓Additional adverse effect code from T36-T50 range identifying the responsible drug
- ✓Whether the causative medication was continued, reduced, or discontinued
- ✓Provider's explicit statement that the polyneuropathy is drug-induced

Commonly Confused Codes
- •G62.1: Alcoholic polyneuropathy is caused by chronic alcohol use, not medication; different etiology and code
- •G62.2: Polyneuropathy due to other toxic agents is for non-drug toxic exposures like heavy metals or industrial chemicals
- •E11.42: Type 2 diabetes mellitus with diabetic polyneuropathy is for diabetes-related neuropathy, not drug-induced
- •G62.9: Polyneuropathy, unspecified should not be used when the drug cause is documented
