Medicare Part B CPT Code Lookup
What Are CPT Codes?
CPT codes are five-digit numeric codes maintained by the American Medical Association (AMA). They standardize medical procedures and services for billing and insurance purposes. These codes are categorized into three types:
-
Category I: Common procedures (e.g., office visits, surgeries).
-
Category II: Performance measurement and tracking (optional).
-
Category III: Emerging technologies and experimental procedures.
Medicare Part B primarily uses Category I CPT codes for billing outpatient services, preventive care, and diagnostic tests.
Understanding Medicare Part B Coverage
Medicare Part B covers medically necessary and preventive services, including:
-
Doctor visits
-
Outpatient care
-
Preventive screenings (e.g., mammograms, colonoscopies)
-
Durable medical equipment (DME)
-
Laboratory tests
-
Ambulance services
Not all CPT codes are covered by Medicare Part B. Some services may require prior authorization or fall under Medicare Part A (hospital insurance).
How Medicare Part B Uses CPT Codes
Medicare uses CPT codes to:
-
Determine if a service is covered.
-
Calculate reimbursement rates.
-
Prevent fraud and incorrect billing.
Each CPT code has a corresponding Medicare Fee Schedule amount, which dictates how much Medicare will pay for the service.
