ICD-10-CM D86.2
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

D86.2 is a billable ICD-10-CM diagnosis code for sarcoidosis of lung with sarcoidosis of lymph nodes. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 196 through 198. Coders also document this condition as bilateral hilar adenopathy. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Immunity disorders.

D86.2 no longer risk-adjusts for Medicare Advantage: it mapped to HCC 112 under the retired CMS-HCC V24 model through payment year 2025 but maps to no category in the live V28 model. It still risk-adjusts in the PACE (CMS-HCC V22) category 112, ESRD (V21) category 112, ESRD (V24) category 112, and RxHCC Part D (V08) category 227 for payment year 2027.

Clinical InformationClinical

  • Sarcoidosis

    an idiopathic systemic inflammatory granulomatous disorder comprised of epithelioid and multinucleated giant cells with little necrosis. it usually invades the lungs with fibrosis and may also involve lymph nodes, skin, liver, spleen, eyes, phalangeal bones, and parotid glands.

Patient EducationClinical

Sarcoidosis

Sarcoidosis is a condition in which groups of cells in your immune system form small, red, and swollen (inflamed) lumps. These lumps are called granulomas. They can form in any organ in the body. But they most commonly affect the lungs and lymph nodes in the chest. Over time, sarcoidosis can cause permanent scarring of organs.

Questions About D86.2Overview

What is the ICD-10 code for sarcoidosis of lung with sarcoidosis of lymph nodes?

The ICD-10-CM code for sarcoidosis of lung with sarcoidosis of lymph nodes is D86.2 (sometimes written as D862). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is D86.2 (Sarcoidosis) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report sarcoidosis of lung with sarcoidosis of lymph nodes on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does D86.2 group to?

When sarcoidosis of lung with sarcoidosis of lymph nodes is the principal diagnosis on an inpatient stay, it groups to MS-DRG 198, 197, 196, with relative weights from 0.7256 to 1.8335 depending on complications. Higher weights mean higher Medicare reimbursement.

Can D86.2 be reported with M35.9?

Not as a rule. The Excludes1 note at block D80-D89, which applies to D86.2, lists "autoimmune disease (systemic) NOS (M35.9)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

What is the ICD-9 equivalent of D86.2?

Under the General Equivalence Mappings, sarcoidosis of lung with sarcoidosis of lymph nodes converts to ICD-9-CM 135 (sarcoidosis). The mapping is approximate, so confirm the match fits the documentation.

Does D86.2 risk-adjust for Medicare Advantage payment?

Not for Medicare Advantage. D86.2 mapped to HCC 112 in the retired CMS-HCC V24 model, which last determined payment in 2025, but it maps to no category in the live V28 model; see all codes that no longer risk-adjust. It still risk-adjusts in the PACE (CMS-HCC V22) category 112 (Fibrosis of Lung and Other Chronic Lung Disorders), ESRD (V21) category 112 (Fibrosis of Lung and Other Chronic Lung Disorders), ESRD (V24) category 112 (Fibrosis of Lung and Other Chronic Lung Disorders), and RxHCC Part D (V08) category 227 (Pulmonary Fibrosis, Except Idiopathic).
