Patient EducationClinical

Lipid Metabolism Disorders

Metabolism is the process your body uses to make energy from the food you eat. Food is made up of proteins, carbohydrates, and fats. Chemicals in your digestive system (enzymes) break the food parts down into sugars and acids, your body's fuel. Your body can use this fuel right away, or it can store the energy in your body tissues.

What MS-DRG does E71.30 group to?

When disorder of fatty-acid metabolism, unspecified is the principal diagnosis on an inpatient stay, it groups to MS-DRG 642 (inborn and Other Disorders of Metabolism), which carries a relative weight of 1.3226. Higher weights mean higher Medicare reimbursement.

Can E71.30 be reported with E71.5?

Not as a rule. The Excludes1 note at E71.3, which applies to E71.30, lists "peroxisomal disorders (E71.5)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

What is the ICD-9 equivalent of E71.30?

Under the General Equivalence Mappings, disorder of fatty-acid metabolism, unspecified converts to ICD-9-CM 272.8 (lipoid metabol dis NEC). The mapping is approximate, so confirm the match fits the documentation.

Does E71.30 risk-adjust for Medicare Advantage payment?

Not for Medicare Advantage: E71.30 maps to no category in the CMS-HCC V28 model. It still risk-adjusts in the RxHCC Part D (V08) category 47 (Disorders of Lipoid Metabolism).
