What is ICD-10 code D86.82?

D86.82 is the ICD-10-CM diagnosis code for Multiple cranial nerve palsies in sarcoidosis. A condition where sarcoidosis, an inflammatory disease, affects multiple nerves in the head and face, causing weakness or paralysis of facial muscles and other cranial nerve functions. D86.82 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. D86.82 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. D86.82 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. D86.82 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 D86.82 map to under V28?

D86.82 has no payable CMS-HCC V28 mapping in the final FY2026 CMS file.

What RAF reference is published for D86.82?

D86.82 has no V28 reference coefficient because the final FY2026 source verifies no payable V28 mapping.

What is the V28 vs V24 difference for D86.82?

D86.82 has verified no payable V28 mapping in the final FY2026 source. Select a historical effective period before making any V24 comparison.

What documentation supports D86.82?

Specify which cranial nerves are affected when documentation is available This code indicates sarcoidosis with neurological complications; ensure the primary sarcoidosis diagnosis is also coded D86.82 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

Documentation must specify sarcoidosis as the established etiology of the cranial nerve palsies, with identification of which cranial nerves are affected.

Supporting evidence should include MRI findings (leptomeningeal enhancement, cranial nerve enhancement), cerebrospinal fluid analysis, and histologic confirmation of sarcoidosis.

Treatment plan including corticosteroids or steroid-sparing immunosuppressants should be documented.

Supporting evidence should include MRI findings (leptomeningeal enhancement, cranial nerve enhancement), cerebrospinal fluid analysis, and histologic confirmation of sarcoidosis.

Treatment plan including corticosteroids or steroid-sparing immunosuppressants should be documented.

Audit Caution

HCC Buddy guidance

This code specifically requires MULTIPLE cranial nerve involvement

if only a single cranial nerve is affected by sarcoidosis, a different code may be more appropriate. Do not assign this code based on suspected neurosarcoidosis without documented confirmation of the diagnosis. Ensure the cranial nerve palsies are currently active, not resolved historical findings.

Common Mistakes

HCC Buddy guidance

G52.7 (Disorders of multiple cranial nerves) captures multiple cranial neuropathies from other causes but should not be used when sarcoidosis is the documented etiology.

D86.89 (Sarcoidosis of other sites) might be used incorrectly instead of this more specific neurosarcoidosis code.

G51.0 (Bell's palsy) should not be assigned when facial nerve palsy is attributed to sarcoidosis.

Is D86.82 an HCC code?

D86.82 is not in the CMS-HCC V28 or V24 community payment model. D86.82 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. D86.82 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.

For D86.82, 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

D86.82 is the ICD-10-CM diagnosis code for multiple cranial nerve palsies in sarcoidosis. A condition where sarcoidosis, an inflammatory disease, affects multiple nerves in the head and face, causing weakness or paralysis of facial muscles and other cranial nerve functions. D86.82 sits in the ICD-10-CM chapter for diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (d50-d89), within the section covering certain disorders involving the immune mechanism (d80-d89).

D86.82 has no mapping under the CMS-HCC V28 or V24 community payment models. D86.82 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. D86.82 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.

Specify which cranial nerves are affected when documentation is available.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for D86.82 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Specify which cranial nerves are affected when documentation is available
•This code indicates sarcoidosis with neurological complications; ensure the primary sarcoidosis diagnosis is also coded

Clinical Significance

Multiple cranial nerve palsies due to sarcoidosis represents significant neurosarcoidosis, a serious complication affecting approximately 5-10% of sarcoidosis patients. Cranial nerve VII (facial nerve) is most commonly involved, but multiple nerve involvement indicates more extensive leptomeningeal or basilar inflammation. This presentation carries a worse prognosis than single nerve involvement and often requires aggressive immunosuppressive therapy.

Documentation Requirements

✓Documentation must specify sarcoidosis as the established etiology of the cranial nerve palsies, with identification of which cranial nerves are affected.
✓Supporting evidence should include MRI findings (leptomeningeal enhancement, cranial nerve enhancement), cerebrospinal fluid analysis, and histologic confirmation of sarcoidosis.
✓Treatment plan including corticosteroids or steroid-sparing immunosuppressants should be documented.

Commonly Confused Codes

•G52.7 (Disorders of multiple cranial nerves) captures multiple cranial neuropathies from other causes but should not be used when sarcoidosis is the documented etiology.
•D86.89 (Sarcoidosis of other sites) might be used incorrectly instead of this more specific neurosarcoidosis code.
•G51.0 (Bell's palsy) should not be assigned when facial nerve palsy is attributed to sarcoidosis.
