ICD-10 Code E71.50 – Peroxisomal disorder, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E71.50 – Peroxisomal disorder, unspecified
What it is
This code identifies a peroxisomal disorder that is not further specified in the record. Peroxisomal disorders are inherited metabolic conditions involving impaired peroxisome function.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings in peroxisomal disorders include developmental delay, hypotonia, seizures, vision or hearing problems, and liver involvement.
When to use this code
Use E71.50 when the provider documents a peroxisomal disorder but does not name a specific subtype. It also fits when the chart confirms a peroxisomal metabolic defect and the exact diagnosis is still pending or unavailable. Code only when the condition is explicitly stated.
Do not use for
Do not use this code for a clearly identified peroxisomal disorder with a more specific ICD-10-CM code. Check documentation if the record only mentions a family history, carrier status, or a nonspecific metabolic concern.
Coding tip
Assign the unspecified code only after confirming that no more specific peroxisomal diagnosis is documented.
