Pain management billing for practices and groups: epidural, facet and sacroiliac joint injections, radiofrequency ablation and stimulator trials, office visits and urine drug testing, worked inside the software you already use.
Pain management billing services turn every visit, injection and procedure into a paid claim. Each injection is coded to the level, side and guidance documented, coverage rules for diagnostic and therapeutic sessions are checked before the procedure, and every payment, denial and patient balance is followed until it is resolved.

Pain management is paid on rules about the patient’s response. Medicare contractors cover spinal injections only for documented indications, under image guidance, within limits on how many sessions a patient can have in a rolling 12 months, and a therapeutic injection usually depends on how much relief a diagnostic one gave. Add radiofrequency ablation and stimulator trials that need authorization, bilateral and multilevel coding, and drug testing with its own frequency rules, and the documentation decides most claims before the code does.
The pain scores and session counts decide the claim. That is why we check the indication, the imaging, the relief documented and the patient’s session history on every injection claim before it goes out, not after it is denied or recouped.
Most pain practices bill spinal injections, ablations and office visits with drug testing in the same week, often for the same patient.

Five of the seven Medicare contractors have coverage rules for sacroiliac joint injections, and they follow the same pattern. A diagnostic injection comes first, to show the joint is the source of the pain. A therapeutic injection is covered only after a diagnostic one gave at least 75% relief, and a repeat therapeutic injection only when the last one gave at least 50% relief or better function for at least three months. Coverage is limited to two diagnostic and four therapeutic sessions in a rolling 12 months.
Each session has to be done under CT or fluoroscopy with contrast, unless a contrast allergy is documented, and the note has to record the pain level at the start and the end. Diagnostic injections are billed with modifier KX on each line. In its 2026 audit, the OIG found that a quarter of the sampled sessions were billed as therapeutic when they were diagnostic.
What we do: before an injection is scheduled, we check the patient’s diagnostic and therapeutic sessions in the past 12 months and the relief documented. Before the claim goes out, we confirm the imaging, the pain scores and modifier KX on diagnostic lines, and fix anything missing the same day.
Pain management claims depend on the level, the side and the guidance used for each injection. The codes below cover most injections and visits, with what payers expect. Commercial plans add their own authorization and bundling rules, and we check each one.
| Code | What it covers | What payers look for |
|---|---|---|
| 99202 to 99215 | Office visits (E/M) | The level matches the decision making or time documented; modifier 25 with a same-day procedure only when the visit is separate. |
| 6232162323 | Interlaminar epidural injections with imaging, cervical or thoracic and lumbar or sacral | Imaging included; the level, approach and drug documented; session limits by spinal region. |
| 64479 to 64484 | Transforaminal epidural injections | Billed for the first level with add-on codes for each additional level, imaging included; 50 when bilateral. |
| 64490 to 64495 | Facet joint injections and medial branch blocks | Billed by level and side with imaging included, and the diagnostic or therapeutic purpose documented. |
| 64633 to 64636 | Radiofrequency ablation of facet joint nerves | By joint level, after diagnostic blocks; authorization from many plans and limits on repeat ablations. |
| 27096 | Sacroiliac joint injection | KX on diagnostic injections; two diagnostic and four therapeutic sessions in a rolling year under Medicare coverage rules. |
| 64451 | Injection of the nerves to the sacroiliac joint | Image guidance included; the same diagnostic and therapeutic rules as 27096. |
| 2055220553 | Trigger point injections | By number of muscles: one or two, or three or more; billed once per session. |
| 63650 | Spinal cord stimulator electrode placement, percutaneous | Usually authorized in advance, with a trial before the permanent implant. |
| 80305 to 80307 | Presumptive urine drug testing | By method; ordered for a documented clinical reason, not as a routine panel. |
| G0480 to G0483 | Definitive drug testing for Medicare | Coded by the number of drug classes tested; CPT 80320 to 80377 are not used for Medicare. |

It is not for every practice. If you are a hospital-employed group whose billing the hospital handles, you do not need us. And if your in-house team keeps denials low and receivables current, keep them, and consider a periodic billing audit instead.
We look at your clean-claim rate, your denials by payer and reason, injection documentation and session limits, drug testing, authorizations, and your aging receivables, and tell you what we find, whether or not you go further with us.
We get access to your practice management system and clearinghouse, load each payer's authorization and bundling rules and your fee schedules, list open authorizations and each patient's recent injection sessions, and agree how escalations work. Most practices are live within one to two weeks.
Visits, injections and procedures are coded and claims submitted within 24 hours. Rejections are corrected the same day, remittances posted as they arrive, pain scores, imaging and session limits checked, and denials worked to their cause, all inside your system.
A report you can read in ten minutes: what was billed and collected by payer, site and service line, what was denied and why, authorizations pending, and what is aging.
You do not change systems to work with Summit Billing Solutions. We work in the practice management and EHR systems below, and through the clearinghouse you already use. If your EHR is not shown, ask; the list grows as we onboard practices.

Pain management revenue rests on injections and procedures that payers review closely, plus office visits and drug testing. Most billing companies take a percentage of collections; a few charge flat monthly or per-claim fees. A percentage keeps the fee tied to procedures that are actually paid.
Summit Billing Solutions charges between 3% and 9% of monthly collections. What moves the number for a pain management practice is the mix of office, injection and surgery center work, procedure volume, authorization volume, and how clean the receivables are when we take them on, which is why we quote your exact rate after the free account review, not before.
