About D86.86
D86.86 is the ICD-10-CM diagnosis code for Sarcoid arthropathy. It belongs to category D86 (sarcoidosis), block D80-D89 (certain disorders involving the immune mechanism) and chapter 3 (diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within D86.8 (sarcoidosis of other sites), D86.86 is specifically for Sarcoid arthropathy. Related codes cover Sarcoid meningitis (D86.81), multiple cranial nerve palsies in sarcoidosis (D86.82), Sarcoid iridocyclitis (D86.83), Sarcoid pyelonephritis (D86.84), Sarcoid myocarditis (D86.85), Sarcoid myositis (D86.87) and sarcoidosis of other sites (D86.89).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 196 (Interstitial Lung Disease with MCC, relative weight 1.8336), DRG 197 (Interstitial Lung Disease with CC, relative weight 0.9492) and DRG 198 (Interstitial Lung Disease without CC/MCC, relative weight 0.7259), in MDC 04 (Diseases and Disorders of the Respiratory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 135 (sarcoidosis).
