A pain specialist may discuss injections, nerve blocks, or an implanted stimulator when other treatment has not helped enough. Before deciding, ask what the procedure is intended to do, what the risks are, and which coverage requirements apply.
The common procedures
- Epidural steroid injections — anti-inflammatory medication delivered near irritated spinal nerves, commonly for radiating leg or arm pain.
- Facet joint injections and medial branch blocks — for arthritis-related spine pain; also used to diagnose which joints generate pain.
- Radiofrequency ablation (RFA) — heat energy quiets the small nerves carrying pain from facet joints, often lasting 6–12 months or longer.
- Spinal cord stimulation (SCS) — an implanted device that masks pain signals, considered for persistent nerve pain after other options; always preceded by a temporary trial.
How Medicare covers them
Medicare covers interventional pain procedures when they are medically necessary under its coverage policies, which typically require an appropriate diagnosis, documented conservative care first, and — for repeat procedures — documented relief from prior ones. Under Part B you pay 20% after the deductible; facility fees may apply depending on where the procedure is done.
Ask whether your plan requires prior authorization, who will submit it, and when you should expect a decision. Do not schedule around an assumed approval date.
Questions to ask the specialist
- What diagnosis are we treating, and how confident are we in it?
- What relief, and for how long, is realistic for this procedure?
- How many of these do you perform, and what are the risks for someone my age?
- What happens if this procedure does not help — what is the next step?
- Will your office handle Medicare or plan prior authorization?
Frequently asked questions
Does Medicare cover epidural steroid injections?
Yes, when medically necessary under Medicare’s coverage policies — typically requiring an appropriate diagnosis and documented conservative treatment first. You pay 20% after the Part B deductible, and Medicare Advantage plans usually require prior authorization.
Does Medicare cover spinal cord stimulators?
Yes, for appropriate candidates with persistent pain after other treatments, and always with a temporary trial first to prove benefit before the permanent implant.
How often will Medicare pay for injections?
Coverage policies limit how frequently repeat injections are covered and require documented relief from previous ones. Your interventional pain specialist’s office manages these requirements.
