Medicare pays for no more than two radiofrequency ablation sessions per spinal region in a rolling 12 months, and only after two diagnostic medial branch blocks that each gave at least 80% relief. Miss either rule and the ablation does not pay, no matter how well the procedure went.
That is the pattern in pain management billing. The procedures are coded correctly far more often than they are covered correctly. Frequency limits, level limits, imaging rules and authorization requirements decide whether a claim pays, and they sit in local coverage determinations, not the CPT book. Facet joint interventions in hospital outpatient departments have required Medicare prior authorization since July 2023, and in 2026 Original Medicare added prior authorization for electrical nerve stimulator implants in six states through the WISeR model, as Baker Tilly explained.
This guide ranks the top 10 pain management billing companies in the USA for 2027. Each profile explains the company’s focus, services, pricing and ideal client, followed by the codes, Medicare rules and denial patterns every pain practice should know.

Top 10 Pain Management Billing Companies in the USA
1. Stream RCM
Stream RCM is a US medical billing and revenue cycle management company based in Texas that offers full-cycle RCM as its core service and individual services on request. For pain practices, that flexibility matters: many need help with one problem first, such as prior authorizations for facet procedures or a backlog of denied injections, before handing over the full revenue cycle.
Pain claims rarely fail at coding. They fail at scheduling, when nobody checks how many sessions the patient has already had in that spinal region, and at authorization, when the approved codes do not match the levels performed. Stream RCM checks coverage, frequency and authorization before the procedure, so problems surface while they can still be fixed.
When a payer still denies, the team identifies the root cause, corrects the claim and files the appeal, then feeds the pattern back to the front desk and providers. For authorization-heavy practices, our prior authorization guide explains the 2026 CMS rules the team works under.

What Is Pain Management Billing?
Pain management billing is the revenue cycle work for pain practices: verifying coverage, obtaining authorizations, coding office visits and interventional procedures, applying local coverage rules, submitting claims and resolving denials. It differs from general billing because so many pain procedures carry frequency limits, level limits and documentation requirements set by Medicare contractors and commercial payers.
What Are the Billing Codes for Pain Management Services?
| Service | CPT Codes | Billing Note |
|---|---|---|
| Interlaminar epidural injection | 62320 to 62323 | Cervical/thoracic and lumbar/sacral, without and with imaging |
| Epidural via catheter | 62324 to 62327 | Continuous or intermittent infusion |
| Transforaminal epidural injection | 64479, +64480, 64483, +64484 | Imaging guidance included |
| Facet joint injection or medial branch block | 64490 to +64495 | Imaging guidance included; add-ons for additional levels |
| Facet radiofrequency ablation | 64633 to +64636 | Requires two prior diagnostic blocks under Medicare LCDs |
| Sacroiliac joint | 27096, 64451, 64625 | Injection, nerve block and radiofrequency ablation, each with imaging |
| Genicular nerve | 64454, 64624 | Block and radiofrequency ablation of genicular nerve branches |
| Trigger point injection | 20552, 20553 | One or two muscles, or three or more |
| Spinal cord stimulation | 63650, 63685 | Percutaneous electrode implantation and generator insertion |
| Kyphoplasty | 22513, 22514, +22515 | Vertebral augmentation |
| Drug testing | 80305 to 80307; G0480 to G0483 | Presumptive (CPT) and Medicare definitive (HCPCS) |

Medicare Rules That Decide Whether Pain Claims Pay
| Rule | What It Requires |
|---|---|
| Facet joint interventions LCD | One spinal region per session, one to two levels per session; up to four diagnostic and four therapeutic intraarticular sessions per region per rolling 12 months |
| Radiofrequency ablation | Two diagnostic medial branch blocks, each with at least 80% relief, before the first ablation; no more than two RFA sessions per region per rolling 12 months |
| Sedation | Moderate sedation or monitored anesthesia care is not routinely reimbursable for facet injections and medial branch blocks |
| Epidural steroid injections | MAC LCDs limit epidural sessions per region per rolling 12 months and require documented response before repeats |
| Hospital outpatient prior authorization | Required for facet joint interventions and implanted spinal neurostimulators in hospital outpatient departments |
| WISeR model (2026) | Prior authorization or pre-payment review for selected services, including electrical nerve stimulator implants, in six states |

Common Pain Management Billing Denials and Fixes
| CARC | Usual Pain Practice Cause | Fix |
|---|---|---|
| 151 | Sessions or levels exceed the LCD frequency limit | Count prior sessions per region before scheduling |
| 50 | Documentation does not show medical necessity, such as missing relief percentages | Record pain scores and relief after each block |
| 197 | Authorization missing for a procedure that requires it | Check payer lists for every scheduled procedure |
| 97 | Imaging guidance or a lesser procedure billed with a code that includes it | Follow NCCI edits and code descriptors |
| 4 | Missing or wrong laterality or bilateral modifier | Match modifiers to the procedure note |
| 16 | Missing level, side or authorization number | Read the RARC and correct the claim |
What Are the CPT Billing Codes for CCM in 2026?
Many pain practices manage chronic conditions over months, which makes care management codes relevant. These are the main codes in 2026:
| Code | Service |
|---|---|
| 99490 / +99439 | Chronic care management by clinical staff, first 20 minutes / each additional 20 |
| 99491 / +99437 | Chronic care management by the physician or QHP, first 30 minutes / each additional 30 |
| 99487 / +99489 | Complex chronic care management, first 60 minutes / each additional 30 |
| 99424 to 99427 | Principal care management for one high-risk condition |
| G0556 to G0558 | Advanced Primary Care Management, created in the 2025 fee schedule |
What Are the Three Types of Billing?
In medical billing, the three types usually refer to professional billing on the CMS-1500 for physician services, institutional billing on the UB-04 for facility services and hybrid billing that combines both. Pain practices that work in their own office, an ambulatory surgery center and a hospital outpatient department often use all three.
Which Company Is Best for Medical Billing?
The best medical billing company depends on the specialty and the problem you need solved. Hospitals usually choose enterprise firms, while specialty practices do better with companies that know their codes and payer rules. For pain management, the top medical billing companies on this list are Stream RCM, Transcure, AnnexMed, The Medicator’s and Medical Billers and Coders, with Stream RCM ranked first for its flexible service model and LCD frequency tracking.
How Much Does Pain Management Cost Out of Pocket?
It depends on the procedure, the setting and the insurance plan. Under Original Medicare, patients usually pay 20% coinsurance after meeting the Part B deductible, and the amount differs between a doctor’s office, an ambulatory surgery center and a hospital outpatient department. Medicare’s Procedure Price Lookup shows national averages by setting. Commercial plans add their own deductibles, copays and prior authorization rules, so checking benefits before scheduling avoids surprise bills.
What Is the Best Pain Medication for Chronic Pain?
There is no single best medication; the right treatment depends on the type of pain, the patient’s health and other medications. The CDC’s 2022 clinical practice guideline says nonopioid treatments are at least as effective as opioids for many common types of chronic pain and should be used first, with opioids considered only when expected benefits outweigh the risks. Patients should talk to their clinician about options.
How to Choose the Right Pain Management Billing Partner
1. Start with your own data. Pull 90 days of denials and group them by payer, CPT code and reason, especially CARC 151, 50 and 197.
2. Ask how they track frequency limits. A strong partner counts sessions per spinal region before scheduling, not after denial.
3. Ask how authorizations reach the claim. Approved codes, levels and dates should match what is billed.
4. Ask for proof. Request clean claim rate, denial rate and days in A/R for pain clients specifically.
5. Compare pricing and scope. Get written pricing that lists what is included, such as authorizations and appeals.
Final Thoughts
The right partner depends on what is breaking in your workflow. Practices that want an integrated platform may favor CureMD. Larger groups may prefer Transcure or AnnexMed. Independent pain practices usually need a team that tracks LCD frequency limits, handles authorizations and lets them start with the problem that costs the most. Stream RCM fits that profile, as a full-cycle partner or one service at a time.
Frequently Asked Questions
What is the best pain management billing company in the USA?
Stream RCM ranks first in this guide for pain practices that want full-cycle billing or help with one problem first, with LCD frequency tracking and prior authorization built into the workflow. Transcure, AnnexMed and The Medicator’s are strong alternatives, depending on practice size and the services you need.
What does a pain management billing company do?
A pain management billing company verifies coverage, obtains prior authorizations, codes office visits and interventional procedures, checks local coverage rules such as frequency limits, submits claims, posts payments and works denials and aging A/R. Many also handle credentialing and care management billing.
How much do pain management billing companies charge?
Most charge a percentage of collections, while others use per-claim or flat monthly pricing. Transcure, for example, reports 5% of net collections. Compare what each price includes, since a low rate that leaves out prior authorizations or appeals can cost more in lost revenue.
Why are pain management claims denied so often?
Most pain denials come from coverage rules rather than coding: sessions that exceed LCD frequency limits, missing documentation of pain relief after diagnostic blocks, missing prior authorization and imaging guidance billed separately when the procedure code already includes it.
How many facet joint injections does Medicare cover per year?
Under the Medicare facet joint LCDs, each spinal region allows up to four diagnostic and four therapeutic intraarticular sessions per rolling 12 months, with one or two levels per session. Radiofrequency ablation is limited to two sessions per region per rolling 12 months.
Does Medicare require prior authorization for pain procedures?
Original Medicare requires prior authorization for facet joint interventions and implanted spinal neurostimulators performed in hospital outpatient departments. In 2026, the WISeR model also added prior authorization or pre-payment review for selected services, including electrical nerve stimulator implants, in Arizona, New Jersey, Ohio, Oklahoma, Texas and Washington. Medicare Advantage and commercial plans set their own lists.
Can imaging guidance be billed separately with pain injections?
Usually not. Transforaminal epidural codes 64479 to 64484, facet codes 64490 to 64495 and the interlaminar epidural codes described as with imaging guidance already include fluoroscopy or CT guidance, so billing it separately leads to a bundling denial.
Should a pain practice outsource its billing?
Outsourcing makes sense when denials for frequency limits or authorizations keep repeating, when staff cannot keep up with payer rules or when A/R keeps aging. A specialty billing partner that tracks LCD rules before scheduling usually recovers more than it costs.
