For interventional pain management practicesThe Treatment Plan Says One Thing. The Coverage Policy Sets the Limit.
Interventional pain management is among the most tightly governed specialties in medicine. Coverage determinations do not merely describe when an injection is appropriate; they cap how many regions and how many levels may be addressed in a single session. A practice can plan a clinically sensible sequence of procedures and find the policy has already decided how much of it is payable.

The Policy Sets Limits the Treatment Plan Does Not.
One spinal region per session. Two levels for certain codes. Numbers in a document, not clinical judgements.
So a Good Session Can Be Partly Unpayable.
Two regions because the pain involves two regions is defensible care and, against the determination, partially unbilled work.
Same-Day Blocks Carry Their Own Burden.
Not forbidden, but not routinely necessary, and each injection's medical necessity must be clearly documented. A combined note does not do it.
And the Rulebook Keeps Moving.
These determinations are revised more often than in most specialties. Templates built two years ago are producing claims against rules that have changed.
Which Makes the Denials Avoidable.
The limits are published in advance. Knowing the current policy is worth more here than being good at appeals.
The limits were published before the session was booked. That is what makes these denials so expensive and so unnecessary.
The detail
Everything below is the evidence for what you just read.
Why are pain management claims denied even when the procedure was indicated?
Because coverage determinations for these procedures contain explicit utilisation limits. Facet joint interventions, both diagnostic and therapeutic, are limited to one spinal region per session, and only two total levels per session are allowed for certain codes.[2]
Those are not clinical judgements. They are numbers in a document. A session that addresses two regions because the patient's pain involves two regions is a clinically defensible session and a partially unpayable one, and the practice usually discovers which on the remittance.
What the Coverage Determinations Actually Limit
Everything below is as Medicare publishes it, cited at the foot of this page.[1][2] These determinations are contractor-specific and are revised frequently, and pain management has more of them, updated more often, than almost any other specialty.
| Where it bites | What the published rule says |
|---|---|
| Regions per session | Facet joint interventions, diagnostic and therapeutic, are limited to one spinal region per session, meaning per date of service. |
| Levels per session | Only two total levels per session are allowed for certain CPT codes, whether two unilateral or two bilateral levels. |
| Multiple blocks in one day | Multiple blocks on the same day are not routinely necessary, because multiple blocks on the same day could lead to improper diagnosis or to a lack of diagnosis. |
| When they are performed anyway | Where multiple blocks are performed on the same day, the medical necessity of each injection must be clearly documented in the medical record. |
| Epidural steroid injections | Governed by their own separate coverage determinations and accompanying billing and coding articles, distinct from those for facet joint interventions. |
| Which policy applies to you | Coverage determinations are issued by Medicare Administrative Contractors and differ between them, so the governing policy is the one your own MAC has in force on the date of service. |
The third and fourth rows are worth reading together. The policy does not forbid multiple blocks in a day; it says they are not routinely necessary and that each one must be separately justified in the record. That is a documentation burden placed directly on the proceduralist.
A Specialty Where the Policy Changes Faster Than the Practice
Pain management coverage policy is unusually active. Determinations are issued, revised and replaced, and the utilisation limits inside them are the parts most likely to move. A practice that built its scheduling and documentation templates around the policy in force two years ago is running against a rulebook it has not read.
Meanwhile the clinical planning happens on a different clock entirely. A proceduralist plans a sequence of diagnostic and therapeutic injections around the patient's anatomy and response, and that plan has no reason to align with a per-session cap written by a contractor.
The result is a specialty where the denials are highly predictable in aggregate and entirely surprising in the moment. Predictable because they cluster around the same limits every month. Surprising because nobody in the room at the time was reading the policy.
What a pain practice usually tracks
- Procedures performed per session.
- Fluoroscopy and facility utilisation.
- Patient-reported response to each block.
- Charges posted for the day.
What it usually does not track
- Regions and levels billed against the per-session limits.
- Which determination governs each procedure, and its current version.
- Whether same-day multiple blocks carried separate documented justification.
- Which denials were utilisation limits rather than medical necessity.
Six Ways Pain Management Revenue Goes Missing
Each of these describes a procedure that was performed, indicated and documented as clinical care. The failure is against a written limit.
Two regions in one session
Clinically reasonable where the pain involves two regions. Facet joint interventions are limited to one spinal region per session, so part of the work is not payable.
Three levels where two are allowed
Only two total levels per session are allowed for certain codes. The third is performed, documented and denied.
Same-day blocks without separate justification
The policy requires the medical necessity of each injection to be clearly documented when multiple blocks are performed on the same day. A single combined note does not do that.
Documentation written for the chart, not the policy
The note explains the procedure and the patient's response. The reviewer is looking for the indication criteria the determination names.
Templates built against a superseded policy
These determinations are revised often. A template that stopped being updated is producing claims against rules that no longer exist.
High-value denials left unappealed
Interventional procedures are expensive. A small number of unappealed denials is a large number of dollars sitting still.
The practical version of all six: pain management is a specialty where knowing the current policy is worth more than working the denials, because the limits are published in advance and the denials are therefore avoidable in advance.
Where This Fits Around What You Already Run
An illustration of the general flow for an interventional pain practice, not a description of any particular practice or contractor policy.
- Evaluation and diagnostic planA sequence of blocks planned around anatomy and response.
- The session is scheduledAgainst clinical logic, which has no reason to match a per-session cap.
- Procedures performedRegions and levels addressed, documented as clinical care.
- The claim meets the determinationWhere regions, levels and same-day justification are measured against published limits.
- Remittance comes backPaid, reduced to the allowed levels, or denied on a limit nobody checked.
- Root cause, not just reworkWhether this is one session or a scheduling habit repeating every week.
- The pattern, and the fixWhich limit, which policy version, which proceduralist, consistently.
What Should a Pain Management Practice Ask a Billing Company?
Nine questions for whoever bills for you now, and for CareVixis. The first three separate a company that reads coverage determinations from one that reacts to remittances.
-
Which determinations govern our procedures, and what version?
If they cannot name them and date them, they are not preventing anything.
-
Do you check regions and levels against the per-session limits before submission?
These limits are published. Checking against them before the claim goes out is entirely possible and rarely done.
-
How do you handle same-day multiple blocks?
The right answer references separately documented medical necessity for each injection, not a combined operative note.
-
Who monitors policy revisions?
In this specialty the policy moves. If nobody owns that, your templates go stale without anyone noticing.
-
What is your appeal rate on utilisation denials?
Some are genuinely unwinnable and some are documentation failures that can be corrected. Ask which is which.
-
Do you feed limits back into scheduling?
The cheapest fix for a per-session cap is knowing about it when the session is booked.
-
Do you perform root cause analysis, as a defined process?
One appealed denial recovers one procedure. Changing how sessions are planned recovers the pattern.
-
Can you work with the systems we already run?
A pain practice should not have to change its EHR to have its coverage limits checked.
-
Is the work performed in the United States?
CareVixis is 100% US-based with zero outsourcing. Ask anyone else the same question and get the answer in writing.
Using Pain Management? Keep It.
Your EHR, your imaging and your procedure scheduling are yours. Nothing on this page requires replacing any of them, and a migration would answer none of the questions above.
Keeping your system is a supported outcome, not a fallback. If you later want to move to the CareVixis platform, that move may be offered at no additional migration charge. Keeping the software you already have carries no monthly software fee from CareVixis.
Keep your systems. Change what is known about the limits before the session is booked.
Questions Pain Management Practices Ask
How many spinal regions can be treated in one session?
Facet joint interventions, both diagnostic and therapeutic, are limited to one spinal region per session, meaning per date of service, under the applicable coverage determination. A session addressing two regions may be clinically reasonable and still be only partly payable.
How many levels are allowed per session?
Only two total levels per session are allowed for certain CPT codes, whether that is two unilateral or two bilateral levels. The specific codes and limits are set out in the coverage determination that applies to your contractor.
Can we perform multiple blocks on the same day?
The policy position is that multiple blocks on the same day are not routinely necessary, because they could lead to improper diagnosis or to a lack of diagnosis. Where they are performed, the medical necessity of each injection must be clearly documented in the medical record. A single combined note describing the session generally does not meet that.
Which coverage determination applies to our practice?
The one your own Medicare Administrative Contractor has in force on the date of service. Determinations for epidural steroid injections and for facet joint interventions are separate documents, they differ between contractors, and they are revised more often in pain management than in most specialties. Establishing which version governs your claims is the first piece of work, not an assumption.
Do we have to change our EHR to work with CareVixis?
No. CareVixis can manage the revenue cycle around the systems a practice already uses. If your EHR, imaging and scheduling work for your proceduralists, keep them. A practice that later wants to consolidate on the CareVixis platform can do that at its own pace.
Keep Pain Management. Add Revenue Intelligence.
Keep your EHR. Keep your imaging. Change what is known about the published limits before the session is booked, rather than after the remittance explains them.

CareVixis publishes no denial rate, recovery rate or revenue figure for pain management practices. Coverage determinations in this specialty are contractor-specific and are revised frequently; the limits that apply to your claims are those in the version your own MAC has in force on the date of service, and confirming that is the first piece of work rather than something to assume.
