About coding lung sarcoidosis
The ICD-10-CM code for lung sarcoidosis is D86.0 (Sarcoidosis of lung). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on D86.0.
Within D86 (sarcoidosis), D86.0 is specifically for sarcoidosis of lung. Related codes cover of lymph nodes (D86.1), of lung with sarcoidosis of lymph nodes (D86.2), of skin (D86.3), of other sites (D86.8) and unspecified (D86.9).
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.
