About coding Biett's disease

The ICD-10-CM code for Biett's disease is L93.0 (Discoid lupus erythematosus).

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.
