About coding pemphigoid
The ICD-10-CM code for pemphigoid is L12.9 (Pemphigoid, unspecified). The official index lists 6 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on L12.9.
Within L12, choose L12.9 (unspecified) only when documentation doesn't support a more specific option: bullous pemphigoid (L12.0), cicatricial pemphigoid (L12.1), chronic bullous disease of childhood (L12.2), acquired epidermolysis bullosa (L12.3) and other pemphigoid (L12.8).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 595 (Major Skin Disorders with MCC, relative weight 2.0239) and DRG 596 (Major Skin Disorders without MCC, relative weight 1.1071), 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.
