This billing and coding guidance complements Local Coverage Determination L34434; follow LCD L34434 for clinical coverage criteria and required documentation for claims.
All services billed with unlisted procedure codes must include sufficient medical records and supporting documentation to allow development and medical review.
The submitted medical record must support the selected ICD-10-CM code(s), and the submitted CPT/HCPCS code must accurately describe the service performed.
The medical record must include the legible signature of the physician or non-physician practitioner responsible for and providing the care.

For tests that currently lack specific CPT codes (functional intracellular analysis and total antioxidant function), bill using CPT 84999 and add a note identifying which test was performed in the Remarks area for Part A claims and the Narrative area for Part B claims.
Coverage and reasonable/necessary determinations for assays for vitamins and metabolic function are governed by LCD L34914 and claims must meet that LCD's requirements to be covered.
Vitamin D assay testing billed to Medicare Part A or Part B MAC is covered when ordered by an authorized provider (physician or state-authorized non-physician) and the service is otherwise consistent with local coverage determination L33996.
A valid ICD-10-CM diagnosis code that best describes the patient's condition prompting the Vitamin D assay must be reported on the claim; for diagnostic tests, report the test result if known, otherwise report the presenting symptoms.
When a referring/ordering provider is required, the referring/ordering provider name and NPI must be reported on the claim.
Esophagogastroduodenoscopy (EGD) is covered when it meets the reasonable and necessary requirements specified in Local Coverage Determination L33583.
