What This Code Means

A group of metabolic disorders affecting how the body processes sulfur-containing amino acids, with the specific type not specified.

Coding Tips

• •Use this code only when the specific sulfur-bearing amino acid disorder cannot be identified; otherwise use a more specific code (E72.11, E72.12, or E72.19)
• •This is an unspecified code and should be avoided if more detailed documentation is available

Clinical Significance

Unspecified disorder of sulfur-bearing amino acid metabolism indicates a defect in the processing of sulfur-containing amino acids (methionine, cysteine, homocysteine) where the specific type has not been determined. These disorders can cause vascular disease, thromboembolism, lens subluxation, and neurological complications. Determining the specific disorder is important as treatment approaches differ substantially.

Documentation Requirements

• ✓Document plasma amino acid levels including methionine and homocysteine, any vascular or thrombotic events, ophthalmologic findings, neurological assessment, and reason the specific sulfur-bearing amino acid disorder has not been identified.
• ✓Record any pending diagnostic workup.
