E71.314 — Muscle carnitine palmitoyltransferase deficiency
E71.314 is a billable, specific ICD-10-CM code for muscle carnitine palmitoyltransferase deficiency. It is valid for submission on a claim.
Excludes1 inherited from the categories above E71.314
These are not written on E71.314, but they bind it: a note on a category applies to every code beneath it. Billing E71.314 with anything listed here is a denial.
Excludes2 inherited from the categories above E71.314
Also inherited, and the opposite of Excludes1: these conditions are not part of E71.314, but a patient can have both, so you may code both.
Other codes that can never be billed with E71.314
These codes carry an Excludes1 note pointing at E71.314. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E71.314 alone.
- E71.4Disorders of carnitine metabolism
Risk adjustment
E71.314 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Medicare coverage
E71.314 is named in 4 Medicare coverage policies — 4 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
