About coding arsenical ingested dermatitis
The ICD-10-CM code for arsenical ingested dermatitis is L27.8 (Dermatitis due to other substances taken internally).
Within L27, choose L27.8 (Dermatitis due to other substances taken internally) only when documentation doesn't support a more specific option: generalized skin eruption due to drugs and medicaments taken internally (L27.0), localized skin eruption due to drugs and medicaments taken internally (L27.1), dermatitis due to ingested food (L27.2) and dermatitis due to unspecified substance taken internally (L27.9).
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.
