Do 2026 Medicare Fee Schedule Updates Raise or Cut Chiropractic Pay?
Medicare's 2026 conversion factor is $33.40 for most clinicians. Here's how RVUs, locality and AT modifier documentation decide what chiropractic codes pay.
The 2026 Medicare Physician Fee Schedule sets the conversion factor at $33.40 for most clinicians, above the $33.29 Medicare used for most of 2024, but what a chiropractic code actually pays still depends on its relative value units and the practice's locality, so the result is not one uniform increase or cut. Medicare recalculates the physician fee schedule every year through a conversion factor, a dollar multiplier applied to the relative value units assigned to each covered service, and chiropractic reimbursement rises or falls based on how that multiplier interacts with the value assigned to the specific CPT codes a practice bills. Because chiropractic coverage under Medicare is limited to manual manipulation of the spine to correct a subluxation, and because Medicare requires that treatment be documented as active care rather than maintenance care, the payment calculation cannot be separated from the documentation rules that determine whether a claim is even payable in the first place. A favorable conversion factor does not protect revenue if the active treatment modifier is applied incorrectly, and a claim billed under the wrong care classification can be denied regardless of what the fee schedule pays for that code. Geographic locality adjustments further change the final reimbursement amount practice by practice, since the fee schedule applies a geographic practice cost index on top of the national conversion factor. Evaluating whether chiropractic pay goes up or down under the 2026 update therefore requires looking at the conversion factor, the RVU values for codes 98940 through 98942, the applicable geographic adjustment, and the documentation standard governing the active treatment modifier together, not any single variable in isolation.
What Actually Changes When the Medicare Conversion Factor Moves
Short answer: the conversion factor moves first, and every chiropractic code gets multiplied against it.
In its 2026 final rule, CMS set the conversion factor for January 1 through December 31, 2026 at $33.40 for non-QP clinicians, which covers most chiropractors, and $33.57 for qualifying alternative payment model participants, after the required budget neutrality adjustment. For comparison, CMS set the 2024 conversion factor at $33.29 for dates of service March 9 through December 31, 2024. So the multiplier itself is higher for 2026 than it was for most of 2024.
Medicare's fee schedule exists to pay enrolled providers for professional services, chiropractic included. But the conversion factor never decides on its own what a claim actually collects. Documentation carries the rest of that weight, and the complete guide to billing active treatment under Medicare walks through how those rules work.
Why a Single National Number Still Produces Different Checks
One national conversion factor sounds like one national outcome. It never works out that way.
Each year, CMS updates its Physician Fee Schedule, which is the main way Medicare pays enrolled providers for their professional services. For chiropractic practices, that annual reset is a critical variable in financial planning, because Medicare's coverage rules are strict and narrow and leave little room for error.
That one dollar figure first passes through a geographic adjustment, then through the RVU value tied to whichever CPT code got billed. So a flat national rate turns into a different check in every region and for every code, and that's before the documentation question underneath it even comes up.
| Fee Schedule Layer | What It Adjusts | Why Chiropractic Claims Are Sensitive to It |
|---|---|---|
| National Conversion Factor | The single dollar multiplier applied to every relative value unit nationwide | A chiropractic code's payment starts here, but the number alone never reflects what a practice actually collects |
| Geographic Practice Cost Index | Local cost-of-practice adjustments applied by locality to the national payment calculation | Identical codes billed in different regions settle at different amounts, so a single fee schedule update lands unevenly across practices |
| Code-Specific Relative Value Units | The weight assigned to each individual CPT code before the conversion factor is applied | Chiropractic billing concentrates on a narrow band of codes, so a small RVU shift on one code moves a disproportionate share of a practice's revenue |
| Active Care Documentation Standard | The clinical record requirement separating payable active treatment from non-covered maintenance care | No conversion factor change matters if the documentation underneath the claim fails the standard Medicare already enforces |
Where Generalist Billing Breaks Down on Chiropractic Specifics
Generalist billing treats the conversion factor as the whole story. It's only the opening line.
The hard claims are where geographic adjustments, code-specific RVUs, and active care documentation all collide, and a process built only to move claims fast skips right past them. That's why sorting fact from myth in Medicare billing rules matters more than the headline number.
The CPT Codes Carrying the Most Weight in This Update
The conversion factor is only the multiplier. The RVU tied to each CPT code decides what actually gets multiplied.
Codes 98940 through 98942 carry the daily weight for chiropractic billing, and each one pays its relative value units times the conversion factor. Whether a practice sees more or less revenue depends on how both numbers land for the codes it bills most, not on the conversion factor alone. Medicare Part B payment changes by region carries the geographic side of that same calculation.
A generalist biller reads the 2026 update and sees one dollar figure move. A specialty biller reads the same rule and checks it against every code a chiropractic practice actually submits.
| CPT Code | Service Description | Billing Consideration |
|---|---|---|
| 98940 | Chiropractic manipulative treatment, spinal, one to two regions | Documentation must support active treatment rather than maintenance care, since Medicare's coverage standard turns on correcting a subluxation, not sustaining a plateaued condition. |
| 98942 | Chiropractic manipulative treatment, spinal, five regions | Highest region count in the core chiropractic code set, which raises the stakes on correct active treatment modifier use given how much revenue runs through it. |
How the AT Modifier Decides Whether a Claim Gets Paid or Flagged
Get the AT modifier right and a payable code gets paid. Get it wrong and that same code gets flagged or denied outright. The modifier's whole job is to tell Medicare the visit was active treatment, not maintenance care.
That one modifier carries more weight than the conversion factor change itself. Chiropractic coverage under Medicare depends on documentation proving active correction of a subluxation, not generic treatment notes. Generalist billing workflows built for volume rarely carry the specialty knowledge to apply that distinction claim by claim, which is exactly why any billing company handling chiropractic claims the same way it handles every other specialty runs into denials that have nothing to do with the fee schedule math.
What Happens When Maintenance Care Gets Billed as Active Treatment
This isn't a coding typo. Maintenance care billed under the active treatment modifier is a documentation mismatch, and no fee schedule update changes how Medicare treats it.
Once that claim gets flagged, it stops heading toward payment and starts heading toward appeal. So a practice that's built its process around denial management and appeals treats the mismatch as a fixable pattern, not a one-off loss. But a generalist process built to move volume rarely slows down long enough to catch it before it happens.
Reading the Fee Schedule for What It Actually Rewards
A fee schedule only rewards what it can see. The conversion factor and the RVU tables measure code-level math, but they can't tell whether that math got applied correctly to the claim actually on the desk.
Under the 2026 update, chiropractic revenue moves on how the national multiplier and code-specific value changes play off each other, never on either one alone. And that's exactly where generalist handling and specialty handling split, landing different outcomes on the same payable code.
| Fee Schedule Component | What Drives the Final Reimbursement Figure |
|---|---|
| CY 2026 Conversion Factor | Sets the dollar multiplier applied to every chiropractic CPT code before any geographic or RVU adjustment is layered on top. |
| Code-Specific RVU Value | Determines what the conversion factor actually multiplies for codes 98940 through 98942, so a change to the relative value units can move payment independently of the conversion factor itself. |
| Geographic Practice Cost Index | Adjusts payment by locality, which is why identical codes with identical documentation can land on different reimbursement figures depending on where the claim originates. |
| Active Treatment Documentation | Governs whether a payable code is paid at all, since the conversion factor and RVU math never override a claim that fails to meet Medicare's active care documentation standard. |
Where RVU Adjustments and Geographic Indexes Meet
The geographic practice cost index adjusts payment by locality, so the same code under the same national conversion factor can still pay different amounts in different places.
A generalist process applies the national conversion factor and stops. Specialty handling checks the RVU change for 98940 through 98942 against the locality index for that specific claim. That's because the final number on a remittance comes from all three layers multiplied together, not the conversion factor sitting by itself.
What a Practice Needs in Place Before the Update Takes Effect
Silence is the default in most billing relationships between submission and payment. That's not a quirk of one vendor. It's a structural failure in how the relationship gets built.
A practice that only hears from its billing partner when something goes wrong has no visibility into how the conversion factor, the RVU changes, and the geographic index are actually landing on its own codes. Fee schedule mechanics stay abstract until someone is actively checking them against what a specific practice bills.
Frequently Asked Questions
That's how the number gets built under the hood. These are the questions that decide what a practice actually sees on its next remittance.
Will all chiropractic services see a payment increase in the 2026 Medicare fee schedule?
No. The conversion factor shift moves every code, but RVU changes for specific codes and geographic adjustments can push individual reimbursements in opposite directions. Whether chiropractic pay rises depends on how those layers net out code by code, not the conversion factor alone.
How does the 2026 conversion factor change impact chiropractic practice revenue?
The conversion factor multiplies against every CPT code a practice bills, so the 2026 figure touches total revenue across the board. The actual dollar impact still depends on which codes a practice submits most, their relative value units, and its locality.
Are there changes to the rules for using the AT modifier for active chiropractic care in 2026?
The fee schedule update changes payment math, not the documentation standard behind the AT modifier. Active treatment still requires proof of correcting a subluxation, and maintenance care billed under that modifier still gets flagged regardless of what the conversion factor pays.
What is the biggest audit risk for chiropractors billing Medicare in 2026?
The fee schedule doesn't create the risk. Documentation does: a claim billed as active treatment without records that support it can be denied, whatever the 2026 rate pays for that code.
How is the 2026 Medicare reimbursement rate for CPT code 98941 determined by region?
Location changes the number. The geographic practice cost index adjusts payment by locality, so two practices billing the identical code under the same national conversion factor can get paid differently, purely because of where the service is performed.
What is the difference between maintenance care and active treatment under Medicare rules?
Active treatment means documented correction of a subluxation, with measurable progress toward a defined goal. Maintenance care is ongoing treatment once that improvement is no longer expected, and Medicare doesn't cover it.
Where This Leaves Chiropractic Practices Billing Medicare in 2026
So does the 2026 update raise or cut chiropractic pay? The multiplier itself went up. But a practice's real number only shows up once the conversion factor, the code-specific RVU, the locality index, and the AT modifier all get checked against the same claim.
Generalist billing reads the conversion factor and calls it done. Specialty handling reads all four layers, because chiropractic coverage lives in the documentation underneath the math, not in the dollar figure sitting on top of it.
That gap is where revenue gets protected or lost under this fee schedule, and closing it is a staffing decision, not a software setting. To see how a practice's own codes, locality, and documentation are actually landing, book a call with Bushido Billing.
