About coding american mucocutaneous leishmaniasis
The ICD-10-CM code for american mucocutaneous leishmaniasis is B55.2 (Mucocutaneous leishmaniasis). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on B55.2.
Within B55 (leishmaniasis), B55.2 is specifically for mucocutaneous leishmaniasis. Related codes cover visceral leishmaniasis (B55.0), cutaneous leishmaniasis (B55.1) and unspecified (B55.9).
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 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.
