ICD-10-CM

Prior Authorization

No Prior Auth Required

Covered without prior authorization (high confidence)

Documentation Required

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.
The patient's medical record must contain documentation that fully supports medical necessity, including relevant medical history, physical examination, and results of pertinent diagnostic tests or procedures.
Each claim must be submitted with ICD-10-CM code(s) that reflect the patient's condition and indicate the reason(s) the service was performed; claims without ICD-10-CM codes will be returned.

Key Coverage Criteria

RAST type tests are covered when medically necessary and supported by the related Local Coverage Determination (LCD) and current medical literature or standards of practice.
Echocardiograms performed as part of the CAMZYOS REMS program are covered when billed with modifier KX and all REMS program requirements are met for patients with NYHA Class II–III obstructive hypertrophic cardiomyopathy (I42.1).
Monitored Anesthesia Care (MAC) is medically necessary when the patient has one or more documented diagnoses listed as supporting medical necessity (e.g., F91.9, G97.81, T81.9XXA, T88.8XXA, F79) and the diagnosis is matched to the anesthesia/CPT/HCPCS procedure performed.
Use G9 anesthesia modifier to indicate need for MAC due to a history of severe or advanced cardiopulmonary disease when the proceduralist determines additional monitoring is required.
Use G8 anesthesia modifier for certain deep, complex, complicated, or markedly invasive surgical procedures when applied to anesthesia codes 00100, 00300, 00400, 00160, 00532, or 00920.
MAC may be appropriate for pediatric patients (Medicare-eligible and younger than 18) when documented using ICD-10-CM code T88.8XXA and clinical records justify the need for MAC.
