How coders use this code
ICD-10-CM E71.448 is a billable, fully specified code, so it can be reported directly on a claim to document a diagnosis of other secondary carnitine deficiency. Coders assign it when the chart documentation supports this level of detail, always matching to the most specific code available and verifying against the chapter-specific guidelines published annually by NCHS/CMS.
