E71.548

HCC Category Mapping

What This Code Means

Other rare inherited metabolic disorders affecting peroxisome function that do not fit into the main peroxisomal disorder categories.

Coding Tips

• •This is a catch-all code for peroxisomal disorders not classified elsewhere; use only when more specific codes do not apply
• •Document the specific peroxisomal disorder identified to support medical necessity

Clinical Significance

This residual code captures peroxisomal disorders not classified in other E71.5 subcategories, including rare single-enzyme defects or newly identified peroxisomal conditions not yet assigned specific codes. Peroxisomal disorders in this category may affect fatty acid chain shortening, ether lipid synthesis, or other specific peroxisomal functions. Clinical presentation depends on the specific pathway affected.

Documentation Requirements

• ✓Document the specific peroxisomal disorder identified, biochemical testing results confirming peroxisomal dysfunction, affected metabolic pathway, genetic testing if available, clinical manifestations, and reason why a more specific peroxisomal code does not apply.
• ✓Record current management approach.
