After booking a test for angina-related concerns, the doctor adjusted the plan and canceled the test. How do I handle the fees I already paid?

First, confirm with the ordering department that the test has been formally canceled, then contact billing or scheduling to verify the refund process. Have the test order, payment receipt, and appointment information ready, and ask whether you need to cancel the appointment, how the refund will be issued, and the expected processing time. Different rules may apply for packages, insurance, or cross-institution payments, so follow the instructions from the relevant institution, and also confirm the adjusted follow-up arrangements.
