Pain Management
Pain management prior authorization: which program, which setting, which proof
In Original Medicare, facet joint interventions (from 1 July 2023) and implanted spinal neurostimulators (from 1 July 2021) need prior authorization when a hospital outpatient department bills them. ASCs and offices are outside that program but not outside every program: epidural steroid injections are on CMS’s WISeR model in six states from 2026, and the LCDs set what each chart must show. A prior authorization seat is $1,900 a month.
The hospital outpatient department program
42 CFR 419.83 lists the service categories. Implanted spinal neurostimulators, and cervical fusion with disc removal, need prior authorization for service dates on or after 1 July 2021. Facet joint interventions joined for service dates on or after 1 July 2023.
The program is about one setting. It covers hospital outpatient department claims in Original Medicare, the ones billed on a type of bill 13x. CMS’s own FAQ says physician offices, critical access hospitals and ambulatory surgery centers that bill on other types of bill are not required to submit requests under it.
Read the code list, not the category name. CMS lists 63650 for neurostimulators and has temporarily removed 63685 and 63688. It removed 64492 and 64495 from the facet list in August 2024, because under the revised facet LCDs three- or four-level procedures are not medically necessary and non-covered.
Decisions: 7 calendar days for standard requests submitted on or after 1 January 2025, and 2 business days for expedited ones.

The programs that do reach ASCs and offices
WISeR is a CMS Innovation Center model that runs from 1 January 2026 to 31 December 2031 in New Jersey, Ohio, Oklahoma, Texas, Arizona and Washington. It covers services in hospital outpatient departments, ambulatory surgery centers, the office and the home. Epidural steroid injections for pain management are on its list, under LCDs L39015, L39240 and L36920. Providers choose between a prior authorization request and a post-service, pre-payment review. Codes already under the OPD program are excluded. Facet joint interventions were not on the list we read on 9 October 2026.
Separately, CMS runs a five-year prior authorization demonstration for certain ASC services in California, Florida, Texas, Arizona, Ohio, Tennessee, Pennsylvania, Maryland, Georgia and New York. Its categories are blepharoplasty, botulinum toxin injections, panniculectomy, rhinoplasty and vein ablation. It is voluntary, but a provider that bypasses it has those ASC claims go to prepayment medical review. If your center bills botulinum toxin injections in one of those states, check it.
Medicare Advantage and commercial plans run their own lists. Since 2024, an MA plan must follow Traditional Medicare’s NCDs and LCDs, and from 1 January 2026 it must decide a standard request within 7 calendar days of receiving it.

What the LCDs ask the chart to show
Facet joints, CGS (L38773): the second, confirmatory diagnostic procedure needs a consistent positive response of at least 80% relief of the primary (index) pain. It may only be done at least 2 weeks after the first. No more than four diagnostic joint sessions are paid per covered spinal region per rolling 12 months, and interventions done without CT or fluoroscopic guidance are not reasonable and necessary.
Facet joints, Noridian (L38801): initial thermal radiofrequency destruction follows at least two diagnostic medial branch blocks, each with a consistent minimum of 80% sustained relief. A repeat at the same site needs at least 50% consistent improvement in pain for six months, or in the ability to perform previously painful movements and activities of daily living.
Epidural steroid injections, Noridian (L39240): a repeat injection needs at least 50% consistent improvement in pain for three months, or in function. An initial injection of contrast is required to confirm placement unless the patient has a contraindication.
These are the thresholds in those MACs’ LCDs. Yours may differ. Commercial plans set their own.

What a prior authorization seat does for a pain practice
One full-time person, $1,900 a month, working inside your own systems and payer portals during US business hours, under a Business Associate Agreement signed before any login.
- Sorts each scheduled facet, RFA, epidural and stimulator case by payer and setting before the date is confirmed
- Builds the request from the chart: diagnostic block dates, the documented relief and how long it lasted, the imaging guidance
- Keeps the rolling 12-month count of diagnostic sessions per spinal region, so the session the LCD will not pay is caught before it is booked
- Submits, chases the status, and books the peer-to-peer for your provider
- Flags authorizations before they expire
- Deciding medical necessity or writing the clinical note: that is your provider’s
- A promised approval: the payer or the contractor decides
Questions
Does an ASC need Medicare prior authorization for facet joint injections?
Not under the hospital outpatient department program, which CMS says applies to hospital OPD claims billed on a type of bill 13x. WISeR’s published list, as read on 9 October 2026, did not include facet joint interventions. Medicare Advantage and commercial plans set their own requirements, so check each plan.
Do epidural steroid injections need prior authorization in a physician’s office?
In Original Medicare they can, under the WISeR model, if the practice is in New Jersey, Ohio, Oklahoma, Texas, Arizona or Washington: from 2026 providers there choose prior authorization or a post-service, pre-payment review. Elsewhere, check the patient’s plan.
How much relief must diagnostic blocks show before radiofrequency ablation?
Under Noridian’s LCD L38801, at least two diagnostic medial branch blocks, each with a consistent minimum of 80% sustained relief of the primary pain. CGS’s L38773 also requires at least 80% relief on the confirmatory block. Read the LCD for your own MAC.
How fast does Medicare decide an OPD prior authorization request?
For requests submitted on or after 1 January 2025, CMS gives 7 calendar days for a standard decision and 2 business days for an expedited one.
What does a pain management prior authorization seat cost?
$1,900 a month for one full-time person, one month minimum, no setup fee. The person works from Rawalpindi, Pakistan, on US business hours, inside your own systems.
