CADS Ambulance Billing & Reimbursement Flashcards

What does 'medical necessity' mean in the context of Medicare ambulance documentation?

Answer: The patient's condition required ambulance transport and could not safely use other means

Medical necessity for Medicare ambulance billing means the patient's condition was such that transport by any other means would endanger the patient's health, as supported by PCR documentation.

Which Medicare audit program specifically targets ambulance service billing compliance?

Answer: Recovery Audit Contractor (RAC)

Recovery Audit Contractors (RACs) review Medicare claims, including ambulance services, for improper payments and documentation deficiencies, and can demand repayment of overpayments.

Under HIPAA, how long must ambulance services retain patient billing records?

Answer: 6 years from creation or last effective date

HIPAA requires covered entities, including EMS agencies, to retain documentation related to protected health information for 6 years from the date of creation or last effective date.

When an ambulance transports a patient to the closest appropriate facility, which documentation element supports this decision?

Answer: Documentation of why the closest facility was appropriate for the patient's condition

PCR documentation must explain why the receiving facility was the closest appropriate facility capable of treating the patient's condition, supporting both medical necessity and billing claims.

Which condition must be documented to bill Medicare for an ALS Level 2 (ALS2) transport?

Answer: Three or more ALS interventions or administration of at least 3 medications

ALS Level 2 requires documentation of three or more separate ALS interventions or administration of at least three medications during transport to qualify for the higher reimbursement rate.

What is the purpose of the 'Origin/Destination' modifiers on ambulance HCPCS claims?

Answer: To identify where the transport began and ended for proper reimbursement

Origin and destination modifiers on ambulance HCPCS codes tell Medicare where the transport started and ended, which determines the applicable fee schedule rate and coverage rules.
