Claims must follow the complementary Local Coverage Determination (LCD L34430) and, when CPT 97000–97799 are used by PT/OT, must include documentation that the services meet the coverage and documentation requirements for physical or occupational therapy.
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.

Therapeutic procedures whose principal aim is to treat a respiratory impairment must be billed using HCPCS codes G0237, G0238, or G0239.
