Medicare National Coverage Determinations Manual

Medicare covers visual tests and general anesthesia for cataract surgery, TENS for acute post-operative pain, inpatient and outpatient pain rehabilitation, and various cardiac procedures including implantation of ICDs and cardiac rehabilitation. Key limitations include coverage exclusions for non-approved indications, frequency restrictions for TENS use, and no coverage for asymptomatic patients undergoing certain surgeries. All procedures require supporting clinical documentation for medical necessity, and prior authorization may be necessary for specific pain management programs.
