Most health insurance plans do cover cortisone shots when a doctor documents the injection as medically necessary for a diagnosed condition such as arthritis, tendonitis, or bursitis. What you actually pay depends on your plan type, where the shot is given, whether prior authorization is in place, and how far you are into your deductible. Without insurance, a single injection runs roughly $100 to $500.
When Insurance Covers the Injection
Private insurers, Medicare, and Medicaid generally pay for cortisone injections as long as a physician documents a specific diagnosed condition and shows that less invasive options have been tried or considered. That documentation matters more than most patients realize. An order that says “knee pain” with no imaging or treatment history attached gives the insurer an easy reason to deny.
Plans also limit how often you can get injections in the same joint. Doctors typically cap treatment at three to four cortisone shots per joint per year because pain relief diminishes with repeated use and the risk of complications like tendon damage goes up. Insurers write similar limits into their coverage policies, and exceeding them almost guarantees a denial.
How your plan classifies the injection matters too. Some employer-sponsored and marketplace plans treat cortisone shots as routine outpatient procedures; others file them under specialist care with higher cost-sharing. If a referral is required to see a specialist, you may need that referral documented before the injection appointment, not after. Your plan’s Summary of Benefits and Coverage spells this out.
What You’ll Pay
Without Insurance
Paying entirely out of pocket, expect $100 to $500 or more per injection. The range depends on which joint is being treated, whether imaging guidance is used, the geographic area, and whether you go to a private office or a hospital-affiliated facility. Many providers offer a cash-pay discount if you ask. Call ahead and get a total that includes the office visit, the injection itself, and the medication.
With Insurance
With coverage in place, your share depends on where you stand relative to your deductible. High-deductible health plans require you to pay the full negotiated rate until you hit the deductible, which for 2026 must be at least $1,700 for individual coverage or $3,400 for a family plan.1Internal Revenue Service. Expanded Availability of Health Savings Accounts under the One, Big, Beautiful Bill Act If you haven’t met that threshold, the insurer’s negotiated rate is your bill.
Once the deductible is satisfied, most plans split costs through either a copayment or coinsurance. A copay is a flat fee, often $20 to $50 for a specialist visit. Coinsurance is a percentage of the total charge, commonly 10% to 30%. Either way, injections at a hospital outpatient department cost substantially more than the same shot given in a doctor’s office because of the added facility fee. One AMA analysis found the median outpatient service was reimbursed 40% more in a hospital setting than in a physician’s office.2American Medical Association. A Comparison of Medicare Pay in the Office and Hospital Outpatient Settings
In-Network Versus Out-of-Network
Staying in-network almost always saves money. Insurers negotiate discounted rates with in-network providers, and those providers cannot bill you for the difference between their standard charge and the negotiated rate. Out-of-network providers have no such agreement and can charge full price. Some plans do not cover out-of-network care at all for non-emergency services.
If an out-of-network provider gives the injection at an in-network facility, the No Surprises Act may limit what you owe. Out-of-network providers at in-network hospitals, hospital outpatient departments, and ambulatory surgical centers generally cannot balance-bill you beyond your in-network cost-sharing amount for covered non-emergency services.3U.S. Department of Labor. Avoid Surprise Healthcare Expenses – How the No Surprises Act Can Help Payments you make under those protections count toward your in-network deductible and out-of-pocket maximum.
Medicare Coverage
Medicare Part B covers cortisone injections as an outpatient procedure when a doctor considers them medically necessary. Because a physician administers the drug rather than you self-injecting at home, it falls under Part B rather than Part D prescription drug coverage.4Centers for Medicare & Medicaid Services. Medicare Part B versus Part D Drug Coverage Determinations Under Original Medicare, the program pays 80% of the approved amount and you pay the remaining 20% after meeting your Part B deductible.
Where you go for the shot makes a surprising difference. For a major joint injection (CPT code 20610), Medicare’s total approved amount in 2026 is about $77 at an ambulatory surgical center but $352 at a hospital outpatient department. Your 20% share jumps from roughly $14 to $69 just by walking into a hospital-affiliated clinic instead of a standalone office.5Medicare.gov. Procedure Price Lookup for Outpatient Services – CPT 20610 The gap exists because hospitals charge a separate facility fee on top of the doctor’s fee. Medicare Advantage plans may structure cost-sharing differently, so check your specific plan’s schedule.
Prior Authorization
Many insurers require prior authorization before they will cover a cortisone injection, particularly for repeat treatments or injections in certain joints. The process is meant to confirm the shot is medically appropriate and not a first resort. Your doctor’s office handles most of the paperwork, but knowing what the insurer wants helps you avoid delays.
The insurer typically wants to see medical records showing a diagnosed condition, imaging results if available, and evidence that conservative approaches like physical therapy or anti-inflammatory medications were tried first. Some plans require authorization for every injection; others approve a set number over a defined period.
Turnaround times range from a few days to a couple of weeks. Plans sometimes expedite requests when a delay would cause significant pain or functional impairment. If the request is denied, the next step is usually a peer-to-peer review, where your doctor speaks directly with the insurer’s medical reviewer to argue for the treatment.6American Medical Association. Fixing Prior Auth – Give Doctors a True Peer to Talk With Asking your doctor to request that call is often faster than a formal written appeal.
Why Claims Get Denied
Even with coverage, individual claims still get rejected. The common reasons are predictable:
- Exceeding frequency limits. If your plan allows three injections per joint per year and your doctor orders a fourth, expect a denial. The insurer’s system flags these automatically.
- Missing or incorrect billing codes. Providers must pair the right procedure code (CPT) with the right diagnosis code (ICD-10). A cortisone injection for knee osteoarthritis needs both the injection procedure code and the osteoarthritis diagnosis code. If those do not match, or a coding error slips in, the claim gets kicked back.7Centers for Medicare & Medicaid Services. Billing and Coding – Pain Management – Injection of Tendon Sheaths, Ligaments, Ganglion Cysts, Carpal and Tarsal Tunnels
- Lack of documented medical necessity. The insurer may want a baseline pain score or functional assessment before approving treatment. For epidural steroid injections, Medicare requires an objective pain scale measurement at baseline and at each follow-up, with repeat injections approved only when the record shows at least 50% sustained improvement. Private insurers often follow similar criteria.8Centers for Medicare & Medicaid Services. LCD – Epidural Steroid Injections for Pain Management
- No prior authorization. Getting the shot before the insurer approves it usually means you pay the full cost yourself.
- Wrong facility type. Some plans only cover cortisone injections given in a physician’s office and deny claims from hospital outpatient departments.
- Global surgery period conflicts. If you recently had surgery on the same joint, your injection may fall within the post-operative global period, during which Medicare and many private insurers bundle follow-up care into the original surgery payment. For major procedures that window is 90 days, and the provider must use the correct modifier to indicate the injection is unrelated.9Centers for Medicare & Medicaid Services. MLN907166 – Global Surgery
Coding errors are the easiest to fix because they involve paperwork, not medical judgment. Ask the billing office to double-check the codes and resubmit. The other reasons require more substantial documentation or a formal appeal.
How to Appeal a Denial
Read the denial letter or Explanation of Benefits carefully. Insurers are required to tell you the specific reason the claim was denied, and that reason dictates your next move. A coding error just needs a corrected resubmission. A medical necessity denial requires clinical evidence.
Internal Appeal
Federal rules give you 180 days from the date you receive a denial notice to file an internal appeal.10HealthCare.gov. Internal Appeals Your doctor can strengthen the appeal by submitting updated medical records, imaging, pain scale measurements, and a letter explaining why conservative treatments failed and the injection is necessary. If the first reviewer upholds the denial, you can request a second-level internal review by a different examiner.
External Review
If your plan upholds the denial after internal appeals, you have the right to an external review by an independent third party. File a written request within four months of receiving the final internal denial.11HealthCare.gov. External Review The external reviewer’s decision is binding. If they side with you, your insurer is required by law to cover the injection. These reviews are overseen by either your state’s insurance department or the federal Department of Health and Human Services, depending on where you live and what type of plan you have.12Centers for Medicare & Medicaid Services. External Appeals
If appeals are exhausted and the denial stands, ask your provider about cash-pay rates or payment plans. The self-pay price is often significantly lower than the sticker price.
Paying With an HSA or FSA
Cortisone injections qualify as eligible medical expenses under IRS rules because they fall within the “costs of diagnosis, cure, mitigation, treatment, or prevention of disease” provided by a physician.13Internal Revenue Service. Publication 502, Medical and Dental Expenses You can use funds from a Health Savings Account or Flexible Spending Account to pay your share, whether that is a copay, coinsurance, or the full cost before meeting a deductible. Using pre-tax dollars effectively discounts the bill by your marginal tax rate. On a $300 injection, that could mean $70 to $100 in tax savings depending on your bracket.
