Which scenario would most likely result in a denial on a Medicare claim?

• A. An Experimental Chemotherapy Medication for a Patient with Stage III Renal Cancer
• B. A Standard Chemotherapy Protocol for Stage II Cancer
• C. A Covered Generic Medication
• D. A Preventive Screening Test

Answer: (A)

Medicare coverage hinges on medical necessity and whether the treatment is proven and approved for the patient’s condition. An experimental chemotherapy medication is considered investigational and not part of standard care, so Medicare generally does not pay for it outside of a registered clinical trial. That makes this scenario the most likely to be denied.

In contrast, a standard chemotherapy protocol for a defined cancer stage reflects established treatment and is typically covered when medically necessary and appropriate. A covered generic medication is usually reimbursed, since generics are approved and listed for coverage. Preventive screening tests are among the services Medicare covers, often with no out-of-pocket cost.
