About coding lichen
The ICD-10-CM code for lichen is L28.0 (Lichen simplex chronicus). The official index lists 36 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on L28.0.
Within L28 (lichen simplex chronicus and prurigo), L28.0 is specifically for lichen simplex chronicus. Related codes cover prurigo nodularis (L28.1) and other prurigo (L28.2).
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 606 (Minor Skin Disorders with MCC, relative weight 1.5728) and DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
