International Classification of Disease (ICD)

The US Department of Health and Human Services (HHS) has mandated the replacement of the ICD-9-CM code sets used by medical coders and billers to report health care diagnoses and procedures with ICD-10 codes, as of October 1, 2015 E78.71 became a billable code for Barth syndrome as a PRIMARY DIAGNOSIS. Supplemental coding information is provided below. Please note it is very important for Barth syndrome code E78.71 to be entered as the primary diagnosis (PDX).

How To Find (Barth syndrome) ICD-10 Diagnostic Code
Endocrine, nutritional and metabolic diseases (E00 – E89)
Metabolic disorders (E70 – E88)
Disorders of lipoprotein metabolism and other lipidemias (E78)
Disorders of bile acid and cholesterol metabolism (E78.7)
Barth syndrome = E78.71 (with dot)
Code Type: Diagnosis
Description: Barth syndrome

ICD-9 to ICD-10 Mapping

The following codes have previously been used as a PDX; however, now that Barth syndrome has a distinct diagnostic code, it is important for these codes to be entered as secondary diagnosis code.
