About coding conglobata acne

The ICD-10-CM code for conglobata acne is L70.1 (Acne conglobata).

Within L70 (acne), L70.1 is specifically for acne conglobata. Related codes cover vulgaris (L70.0), varioliformis (L70.2), tropica (L70.3), infantile acne (L70.4), excoriee (L70.5), other acne (L70.8) and unspecified (L70.9).

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 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.
