ICD-10 Code E74.29 – Other disorders of galactose metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E74.29 – Other disorders of galactose metabolism
What it is
E74.29 identifies other specified disorders affecting galactose metabolism. Use it for inherited or acquired problems in how the body processes galactose when the record does not fit a more specific galactose disorder.
Clinical signs
Clinical features vary; refer to documentation. Records may note abnormal galactose handling, intolerance, or metabolic findings tied to a galactose-processing disorder, but the exact presentation depends on the underlying condition.
When to use this code
Use this code when the clinician documents a disorder of galactose metabolism and no more specific ICD-10-CM code applies. It is appropriate for charted “other” or unspecified subtypes that are clearly distinct from classic galactosemia.
Choose it only when the documentation supports a true metabolic disorder, not a temporary dietary issue. If the note is vague, check documentation before coding.
Do not use for
Do not use E74.29 for classic galactosemia or other specifically named galactose disorders that have their own codes. Do not use it when the record only mentions lactose intolerance or a nonspecific feeding problem.
Coding tip
Code the most specific galactose disorder documented, and query the provider if the record only says “galactose problem” or “metabolic disorder.”
