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.
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.
Supporting documentation must demonstrate that CPT 31720 was personally performed by the physician or qualified NPP when billing that code.
For consecutive days of respiratory therapy, the medical record must document why the patient was not transferred to a higher level of care.

Therapeutic procedures whose principal aim is to treat a respiratory impairment must be billed using HCPCS codes G0237, G0238, or G0239.
CPT 94762 is medically necessary when intermittent arterial blood gas sampling is likely to miss important variations in the patient's respiratory status.
CPT 94762 is medically necessary when the patient has hypoxemia and there is a need to assess supplemental oxygen requirements and/or a therapeutic oxygen regimen.
Diagnostic polysomnography or other sleep testing is covered when the patient has symptoms or complaints of one of the conditions listed in LCD L36839.
A single polysomnogram (PSG) with EEG is ordinarily sufficient and covered to evaluate and diagnose suspected obstructive sleep apnea (OSA).
Diagnosis of narcolepsy is ordinarily confirmed by up to three Multiple Sleep Latency Test (MSLT) naps; MSLT (CPT 95805) performed appropriately is covered for this indication.
