About coding I albinism
The ICD-10-CM code for I albinism is E70.320 (Tyrosinase negative oculocutaneous albinism).
Within E70.32 (oculocutaneous albinism), E70.320 is specifically for Tyrosinase negative oculocutaneous albinism. Related codes cover Tyrosinase positive oculocutaneous albinism (E70.321), other oculocutaneous albinism (E70.328) and unspecified (E70.329).
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.
