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.
When G9 modifier is used for history of severe cardiopulmonary disease, document the clinical decision-making process and the need for additional monitoring in the medical record.

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.
Vitamin D assay testing is payable under Medicare Part B when performed in an office (POS 11), independent clinic (POS 49), Federally Qualified Health Center (POS 50), or independent laboratory (POS 81).
Non-physician practitioners (e.g., nurse practitioners, clinical nurse specialists, physician assistants) may certify, order, and establish the plan of care for Vitamin D assay testing as authorized by State law (outpatient settings other than CORFs).
