This article provides billing, coding and guideline information that complements Local Coverage Determination (LCD) L33431 for HbA1c; refer to LCD L33431 for clinical coverage criteria and specific documentation requirements.
All documentation supporting MAC must be maintained in the patient's medical record, be legible, include complete patient identification and dates of service, and be made available to the contractor upon request.
The medical record must include the legible signature of the physician or non-physician practitioner responsible for and providing the care.
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.

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.
