Epidural Steroid Injection Cost: $265 in an Office, $1,003 in a Hospital
The shot people get for sciatica is a lumbar transforaminal epidural steroid injection, CPT 64483. Medicare allows $264.87 for it in a doctor's office and $1,003.16 for the identical procedure in a hospital outpatient department. Same needle, same steroid, same fifteen minutes. Your 20% share goes from $52.97 to $200.63 because of the building. Below is every epidural code at all three sites of care, priced off Medicare's published rates for October through December 2026.
- The site of care is the bill. A lumbar transforaminal epidural runs $264.87 in an office, $585.04 in a surgery center and $1,003.16 in a hospital outpatient department. That is a $738.29 swing for the same procedure.
- Medicare caps these at four sessions per spinal region per rolling twelve months, and its coverage policy says plainly that prescribing a predetermined series of injections is not medically reasonable and necessary. If you were told you need "a series of three," that is not a medical rule.
- In 2024, physicians billed an average of $2,148.45 for a facility-based 64483 and Medicare allowed $255.33. That 8.4x charge is the number that lands on you if you are uninsured or out of network.
What Medicare Allows, by Code and by Place
In an office the single fee covers everything. In a surgery center or hospital you get two bills for one procedure: the doctor's professional fee, which drops by roughly 60% in a facility, and the facility's own fee, which more than replaces it. The totals below add both. These are national rates for October 1 through December 31, 2026, before any local geographic adjustment.
| Procedure (CPT) | Office | Surgery center | Hospital outpatient |
|---|---|---|---|
| Transforaminal epidural, lumbar or sacral, 1 level (64483)The sciatica injection | $264.87 | $585.04 | $1,003.16 |
| Interlaminar epidural, lumbar or sacral, with imaging (62323) | $273.22 | $476.64 | $810.35 |
| Transforaminal epidural, cervical or thoracic, 1 level (64479) | $285.24 | $602.08 | $1,020.20 |
| Interlaminar epidural, cervical or thoracic, with imaging (62321) | $276.56 | $482.99 | $816.70 |
| Each additional transforaminal level, lumbar (64484) | +$117.57 | +$43.76 | +$43.76 |
| Each additional transforaminal level, cervical or thoracic (64480) | +$142.96 | +$53.11 | +$53.11 |
Office = CMS Physician Fee Schedule non-facility rate. Surgery center = facility professional fee plus the ASC payment rate. Hospital outpatient = facility professional fee plus the OPPS payment rate.
Your 20% Share, Same Procedure, Three Places
| What you are having done | Office | Surgery center | Hospital |
|---|---|---|---|
| One lumbar transforaminal epidural | $52.97 | $117.01 | $200.63 |
| A two-level lumbar transforaminal epidural | $76.49 | $125.76 | $209.38 |
| The maximum Medicare will cover in a year: four lumbar sessions | $211.90 | $468.03 | $802.53 |
Add the $283 Part B deductible if you have not met it yet this year. Original Medicare has no annual out-of-pocket maximum, so nothing stops the hospital column from recurring every year. How Part B coinsurance adds up without a cap.

The Extra Level Is Free in a Hospital and $117.57 in an Office
This is the one place the office is not the cheaper option, and it is worth understanding because it explains a lot of what you will see on the bill. Code 64484 covers each additional nerve root level beyond the first. In an office it carries its own full fee of $117.57. In a surgery center or hospital, it is a packaged code: the facility gets paid nothing extra for it, because the facility fee for the first level already covers the whole session. Only the doctor's add-on of $43.76 gets added.
So a two-level lumbar injection is $382.44 in an office and $1,046.92 in a hospital. The gap narrows slightly with each level, and it never closes. The office is still less than half the price at three levels, which is the most Medicare will pay for anyway.
What this means on a hospital bill
If your hospital statement shows a separate charge for each additional level, that is a charge the hospital is not paid for and should not generate separate patient responsibility under Medicare. Packaged codes are paid at zero by design. Ask for the itemized bill and the remittance advice, and compare what was charged against what was allowed line by line.
What Providers Actually Charge
Medicare publishes both the average charge submitted and the average amount allowed, for every code, every year. The gap is not a rounding error. These are 2024 figures for the professional fee only, on services done in a facility, and the facility's own charge is on top of them.
| Code | Average charge | Average allowed | Multiple |
|---|---|---|---|
| 64483 transforaminal epidural, lumbar | $2,148.45 | $255.33 | 8.4x |
| 62323 interlaminar epidural, lumbar | $1,537.88 | $174.66 | 8.8x |
| 64479 transforaminal epidural, cervical | $2,197.00 | $259.60 | 8.5x |
| 64484 each additional lumbar level | $627.09 | $52.73 | 11.9x |
If you have insurance, you never see these numbers and they do not matter. If you are uninsured, out of network, or on a plan that pays a percentage of billed charges, the charge column is your bill. The allowed column is what the same provider accepts from Medicare for the same work, and it is the honest starting point for a negotiation. We do that negotiation.
The Rules Medicare Applies, in Plain English
Epidural steroid injections are governed by detailed local coverage determinations that every Medicare contractor publishes. They are unusually specific, and most of the limits are things a patient can check on their own bill. These come from LCD L39240, revised April 16, 2026.
It has to be nerve pain, not back pain
Covered for radiculopathy, radicular pain or neurogenic claudication from a disc herniation, osteophyte, severe degenerative disc disease or stenosis, for post-laminectomy syndrome, or for acute shingles pain. Injections for non-specific low back pain, axial spine pain, complex regional pain syndrome, widespread diffuse pain or cervicogenic headaches are called investigational and not medically reasonable and necessary. Sciatica from a herniated disc is squarely inside the covered list. "My back hurts" is not.
Four weeks of trying something else first
Pain of at least four weeks' duration, plus either documented failure of four weeks of noninvasive conservative care or an inability to tolerate it. Acute shingles is the exception and does not need the wait. A baseline pain or function score has to be recorded before the injection and repeated at follow-up with the same scale.
Four sessions per spinal region per rolling twelve months
That is the ceiling regardless of how many levels are involved. One spinal region per session, so cervical and lumbar on the same day is not covered. Transforaminal injections are limited to two nerve root levels in a session, and interlaminar and caudal injections to one level and never bilaterally.
No predetermined series
The policy states directly that it is not medically reasonable and necessary to prescribe a predetermined series of injections. A repeat is justified by the first one working: the record must show at least 50% consistent improvement in pain for at least three months, or the same improvement in function. If you were booked for three shots before anyone knew whether the first one helped, that booking is not what Medicare pays for.
Sedation is almost never covered
Moderate or deep sedation, general anesthesia and monitored anesthesia care are "usually unnecessary or rarely indicated" and therefore not medically reasonable and necessary. The policy notes that oral anxiolytics typically suffice even for needle phobia, and that deep sedation is actively discouraged because a sedated patient cannot warn the doctor about a nerve being touched. An anesthesia line on an epidural bill is worth a hard question. How to handle a surprise anesthesia charge.
Image guidance is required, and it is already in the price
Fluoroscopy or CT with contrast, unless you have a documented contrast allergy or are pregnant, in which case ultrasound may be used. Injections done with no guidance, or with ultrasound outside those exceptions, are not covered. Note that codes 62321, 62323, 64479, 64483, 64490 and 64493 all include imaging guidance in the code itself, so a separate fluoroscopy charge alongside them is a duplicate.
Not past twelve months
The policy says treatment with epidural steroid injections generally would not be considered reasonable and necessary beyond twelve months, and that continuing past that point may trigger review. It also caps the steroid dose per session.
Six Things to Check on an Injection Bill
1. A facility fee you did not expect
A pain clinic physically inside a hospital, or one the hospital bought, bills as a hospital outpatient department. That is the entire difference between $264.87 and $1,003.16. The tell is a second statement with the hospital's name on it, or a place-of-service code of 19 or 22 rather than 11. Ask before you book, not after.
2. A separate fluoroscopy charge
Codes 77003 and 77012 cover spinal injection guidance, and the epidural codes above already include it. A line for 77003 next to 64483 on the same date is the classic unbundling error on these bills, worth $104.54.
3. Code 62322 instead of 62323
62322 means the injection was done without image guidance. Medicare's own coverage policy says injections without image guidance are not reasonable and necessary. If 62322 is on your bill and you remember an X-ray machine in the room, the code is wrong. Oddly, in a hospital the no-imaging version pays the facility $182.46 more, so the error is not always in your favor to leave alone.
4. More than two levels, or two regions on one day
Transforaminal injections above two nerve root levels in one session are not covered. Neither is injecting your neck and your low back on the same day. Count the units of 64484 or 64480 on the claim.
5. An anesthesia bill
A separate anesthesiologist or CRNA charge for a fifteen-minute injection is outside what Medicare considers necessary absent specific documentation. This is one of the most common surprise lines on these bills and one of the most winnable to dispute.
6. A fifth session inside twelve months
Count your injections per region over the last year. The fifth is not covered, which means it is your full responsibility if it was done anyway, and you should have been given an advance beneficiary notice before it happened. If you were not, that is an argument.
How to Pay Less
Ask one question before you book: is this billed as an office or a hospital outpatient department?
It is the single highest-value question in this entire guide and it saves up to $738.29 per injection, $147.66 of it out of your own pocket. Independent pain management and physiatry practices usually bill as offices. Hospital-affiliated spine centers usually do not.
If it has to be a facility, ask for a surgery center
An ambulatory surgery center is allowed $485.51 for the facility side of a lumbar transforaminal epidural. A hospital outpatient department is allowed $903.63 for the exact same thing. That is $418.12 of pure site difference, and you pay 20% of it.
Do not agree to a series up front
Book one. See whether it helps. Medicare's own policy says a predetermined series is not justified, and a second injection is only covered if the first one produced documented, sustained improvement. Three unnecessary hospital injections is $3,009.48 allowed and $601.90 out of pocket.
Decline sedation unless there is a real reason
It adds an entire second professional bill, it is usually not covered, and Medicare's contractors specifically say it makes the procedure less safe rather than more.
If you are uninsured, open with the Medicare number
The charge on your statement is likely to be eight to nine times what the same provider accepts from Medicare for the same code on the same day. Knowing the allowed amount changes the conversation completely. Where else to get help with a bill.
How Common This Is
In 2024, Medicare paid for 898,002 lumbar transforaminal epidural injections. 578,930 of them, 64%, were done in a facility rather than a doctor's office, which is the expensive column of the table above. Add the other epidural approaches and the total is 2,118,600 injections in one year. Widen it to the whole family of spinal injections, including facet blocks, radiofrequency ablation and sacroiliac joint injections, and it is 4,394,059 services. That is traditional Medicare alone, so it excludes Medicare Advantage and everyone with commercial insurance.
The Rest of the Back Pain Path
Common Questions
How much does an epidural steroid injection cost?
For the lumbar transforaminal injection usually given for sciatica, Medicare allows $264.87 in a doctor's office, $585.04 in an ambulatory surgery center and $1,003.16 in a hospital outpatient department. On Original Medicare you owe 20%, so $52.97, $117.01 or $200.63, plus the $283 Part B deductible if you have not met it. Those are national rates for October through December 2026. Commercial insurers typically pay more, and the average charge submitted for the professional fee alone was $2,148.45 in 2024.
Does Medicare cover epidural steroid injections for sciatica?
Yes. Radicular pain from a disc herniation, osteophyte, severe degenerative disc disease or spinal stenosis is explicitly covered, which is what sciatica is. What is not covered is an injection for non-specific low back pain or axial spine pain with no nerve involvement, which Medicare's contractors call investigational. You also need at least four weeks of pain and documented failure of or inability to tolerate four weeks of conservative care first.
How many epidural injections can you have in a year?
Medicare covers a maximum of four sessions per spinal region in a rolling twelve-month period, regardless of how many levels are injected, and only one spinal region per session. Beyond that it also says treatment generally should not extend past twelve months. A fifth session inside twelve months is your full financial responsibility, and the provider should give you an advance beneficiary notice before doing it.
Do I need a series of three epidural injections?
No. Medicare's coverage policy states directly that it is not medically reasonable and necessary to prescribe a predetermined series of epidural steroid injections. A repeat injection is covered only when the medical record shows the previous one produced at least 50% consistent improvement in pain for at least three months, or the same improvement in function. The "series of three" is a scheduling convention, not a clinical requirement.
Why was my epidural injection so much more expensive at the hospital?
Because you were billed twice for one procedure. The doctor's professional fee drops from $264.87 to $99.53 in a facility, but the hospital then bills its own facility fee of $903.63 on top. The total is $1,003.16 instead of $264.87. A surgery center does the same thing but its facility fee is only $485.51. Nothing about the procedure itself changes.
Should I be sedated for an epidural steroid injection?
Medicare's coverage policy says moderate or deep sedation, general anesthesia and monitored anesthesia care are usually unnecessary or rarely indicated for these procedures and are not medically reasonable and necessary without specific documentation. It notes that oral anxiolytics typically suffice, and that a 2015 multidisciplinary workgroup raised safety concerns about sedation because an awake patient can alert the doctor to nerve contact. If sedation is offered as routine, ask what it will be billed as.
