About coding erythematosus lupus
The ICD-10-CM code for erythematosus lupus is L93.0 (Discoid lupus erythematosus). The official index lists 24 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on L93.0.
Within L93 (lupus erythematosus), L93.0 is specifically for Discoid lupus erythematosus. Related codes cover subacute cutaneous lupus erythematosus (L93.1) and other local lupus erythematosus (L93.2).
Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
