Epidurals, facet and medial branch blocks, and SI joint injections coded by region, level, and laterality.
Radiofrequency ablation and spinal cord stimulator trials and implants with their strict auth and level rules.
Obtaining and matching authorizations to the exact procedure and levels — the #1 way pain claims are lost.
Applying the correct imaging-guidance rules per procedure so fluoroscopy neither bundles nor double-bills.
Presumptive and definitive UDT billed to medical-necessity, frequency, and documentation policy — a top audit target.
We appeal frequency, medical-necessity, and bundling denials with documentation and fix the front end that causes them.
Few specialties face tighter payer scrutiny than interventional pain management. Nearly every procedure requires prior authorization, most carry frequency caps, imaging-guidance bundling rules change by code, and the whole specialty sits under a compliance microscope because of controlled substances and drug testing. The revenue is real and the procedures are high-value — but so is the denial rate when the billing isn't disciplined. Pain management rewards a team that treats payer policy as the operating manual, not an afterthought.
Interventional pain billing is built on spinal injections, and the coding turns on region, level, and side. Facet joint injections and medial branch blocks use primary plus add-on codes by level (for example, 64493 with 64494/64495 for additional lumbar levels), transforaminal epidurals are billed per level, and bilateral procedures need the correct RT/LT or modifier 50 handling. Miscount the levels or misapply the add-on and bilateral rules and the claim underpays or denies. Distinct services performed at the same session may need modifier 59 or an X{EPSU} modifier to be paid separately — applied only when the documentation supports it.
Epidurals, facet procedures, radiofrequency ablation, and spinal cord stimulators nearly all require prior authorization — frequently with documented conservative treatment (physical therapy, medication, prior injection response) that must appear in the record before approval. A missing or mismatched auth is the single largest denial category in pain management: the procedure is done, the money is at risk, and it shows up as CO-197. Our team clears authorization before the procedure and matches it to the exact codes and levels billed, so nothing denies after the fact.
Imaging guidance is a bundling minefield. Many spinal injection codes already include fluoroscopy (bundling 77003), while others allow it separately — bill it against a code that includes it and you get a CO-97 or CO-236 bundling denial. On top of that, payers cap how many injections and ablations they'll cover per region per period; exceed the limit and the claim denies as CO-151 (frequency/units). We apply the guidance rules per procedure and track frequency caps by payer so procedures aren't performed into a denial.
Urine drug testing is legitimate and important in pain management — and one of the most audited services in all of billing. Presumptive and definitive testing carry strict medical-necessity, frequency, and documentation rules, and over-testing or template ordering is exactly what draws payer and regulator attention. We bill drug testing to policy, support the medical-necessity documentation, and keep frequency defensible, so a compliant clinical practice is matched by compliant billing. Across the whole revenue cycle we track the practice's denial rate and route the recoverable denials through structured denial management — because in pain management, the difference between a healthy margin and a struggling one is almost entirely front-end discipline.
Specialties that refer into and out of pain management, and share its procedural coding.
Shared board certification and shared procedural coding, including fluoroscopic guidance rules.
Spine and joint patients move between both practices throughout a conservative-care pathway.
Neuropathic pain and headache are jointly managed, with overlapping diagnostic testing.
Interventional procedures are usually paired with a therapy plan of care that must document function.
We bill all of these in house. If your group spans several of them, multi-specialty billing keeps one team across every line — or see the full list of services.
