Epidural steroid injections in the US: will Medicare or your insurance pay?

What Medicare requires

Medicare’s epidural steroid injection LCDs (for example Wellpoint Federal L39036 and Noridian L39240) cover the injection when:

• you have radicular pain (pain spreading into an arm or leg, such as sciatica) or neurogenic claudication, caused by a disc herniation, bone spurs or severe disc degeneration, or you have post-laminectomy pain or acute shingles pain
• the pain has lasted at least 4 weeks and 4 weeks of conservative care, such as physical therapy, exercise or medicines, hasn’t helped (or you couldn’t tolerate it)
• imaging matches your symptoms, and your pain and function are scored on a standard scale before and after
• the injection is done with fluoroscopy (live X-ray) or CT guidance and contrast dye

Repeat injections are generally covered only if the last one gave at least 50% relief for at least 3 months, or a 50% improvement in function. The limit is 4 sessions per spine region in a rolling 12 months, and injections should be part of an active rehab or home exercise program.

Medicare does not cover epidurals for back pain without leg or arm symptoms, injections without image guidance, a pre-planned “series” of injections, or routine sedation or anesthesia.

What it costs with Medicare

In 2026, Medicare’s national approved amount for a lumbar interlaminar epidural (CPT 62323), including the doctor’s fee, ranges from about $270 to $810, depending on where it is done: usually lowest in a doctor’s office, higher in an ambulatory surgery center and highest in a hospital outpatient department. Your 20% share is about $55 to $160.

These are national figures from CMS’s 2026 payment files, not a quote. Actual amounts vary by location, extra levels add to the cost, and you pay the Part B deductible first. A Medicare Supplement (Medigap) policy or other secondary coverage may pay your 20%. Medicare Advantage plans set their own copays.

Private insurance

• Most plans cover epidural injections for nerve-root pain, and many need prior authorization. UnitedHealthcare’s commercial plans review some epidural codes when the injection is done in a hospital outpatient department or surgery center rather than an office (some states, including Illinois, are exempt).
• Aetna covers them after at least 4 weeks of failed conservative care, up to 3 per region per episode within 6 months and 4 per region in 12 months, and treats epidurals for back pain without nerve symptoms as experimental.
• UnitedHealthcare requires at least 4 weeks of failed conservative care, nerve-root involvement on imaging or nerve testing, fluoroscopy or CT guidance, and a maximum of 4 sessions per region in 12 months.
• Cigna’s interventional pain precertification is run by eviCore; some Blue Cross plans use Carelon.

Self-pay prices

Published self-pay prices we found from US providers ranged from about $480 to $1,000 for one level. What a price includes varies a lot: some cover only the doctor’s fee, while others include the facility, imaging guidance, sedation and medicine. Prices change, so ask the provider for a written Good Faith Estimate.

How Medicare decides

Original Medicare covers these procedures under Part B when they are medically necessary. For most pain procedures there is no national rule. Instead, the regional company that processes Medicare claims in your state (a Medicare Administrative Contractor, or MAC) publishes a local coverage determination (LCD). The LCDs for each procedure are nearly identical across the country. In Illinois, Minnesota, Wisconsin, New York and New England, the contractor is Wellpoint Federal, formerly National Government Services.

Medicare Advantage plans must follow the same national and local coverage rules, but they can require prior authorization. Since January 2026, they must decide standard prior authorization requests within 7 calendar days and urgent ones within 72 hours. How coverage works in the US.

If you’re uninsured or paying yourself

Under the No Surprises Act, if you don’t have insurance or choose not to use it, you have the right to a written Good Faith Estimate when you schedule a service at least 3 business days ahead, or whenever you ask. If your final bill from a provider is at least $400 more than its estimate, you can dispute it with the federal patient-provider dispute process within 120 days of the bill date. There is a small fee.

Ask whether a cash price includes the doctor, the facility, imaging guidance, sedation and the medicine itself, because published prices differ in what they cover.

Paying with an HSA or deducting it

Medical procedures and physical therapy that treat a medical condition are generally qualified medical expenses for a health savings account (HSA) or flexible spending account (FSA). In 2026 you can put up to $4,400 (self-only) or $8,750 (family) into an HSA if you have a qualifying high-deductible plan. If you itemize, unreimbursed medical expenses above 7.5% of your adjusted gross income can be deducted.

If you are denied

• Private plans: ask for the denial and the policy it relies on in writing. You have 180 days from the denial notice to file an internal appeal; in urgent cases the plan must decide within 72 hours. If the plan still says no, you can ask for an independent external review within 4 months, and the insurer must accept the reviewer’s decision.
• Original Medicare: you have 120 days from the date on your Medicare Summary Notice to ask for a redetermination.
• Medicare Advantage: ask your plan for a reconsideration within 65 days of the denial notice.
• Your doctor’s office can often help with a peer-to-peer review or a letter of medical necessity. Your state insurance department can also help with complaints about private plans.
