About coding Hepatocutaneous type porphyria
The ICD-10-CM code for Hepatocutaneous type porphyria is E80.1 (Porphyria cutanea tarda).
Within E80 (disorders of porphyrin and bilirubin metabolism), E80.1 is specifically for porphyria cutanea tarda. Related codes cover hereditary erythropoietic porphyria (E80.0), other and unspecified porphyria (E80.2), defects of catalase and peroxidase (E80.3), Gilbert syndrome (E80.4), Crigler-Najjar syndrome (E80.5), other disorders of bilirubin metabolism (E80.6) and disorder of bilirubin metabolism, unspecified (E80.7).
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 642 (Inborn and Other Disorders of Metabolism, relative weight 1.3219), in MDC 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
