This article provides billing/coding guidelines that complement Local Coverage Determination L34417 for CT of the head; consult LCD L34417 for specific coverage, coding, and documentation requirements.
A specific written order (referral/prescription) by the physician or appropriate NPP must be on file for all respiratory care services.
Medical records must fully document that services were reasonable and medically necessary, with results and usage of the test documented in the record and available upon request.
Each claim must be submitted with ICD-10-CM code(s) that reflect the patient's actual condition; listing a diagnosis code alone does not justify the test without supporting clinical context.
