CPT Code 98943: Chiropractic manipulative treatment, extraspinal

Key Takeaways

CPT Code 98943 describes chiropractic manipulative treatment (CMT) applied to one or more extraspinal regions: head/neck (non-spinal), rib cage, abdomen, upper extremities, and lower extremities. Treating all five in one visit is not required.

Medicare does NOT cover CPT 98943. Billing Medicare for extraspinal CMT is a high-denial, high-audit risk. Only commercial payers may reimburse this code.

SOAP notes must document medical necessity for each extraspinal region treated. Vague or missing region-specific documentation is the leading cause of 98943 claim denials.

Pabau’s claims management software helps chiropractic practices automate CMT code selection, track documentation completeness, and submit HIPAA-compliant claims for 98943 and related codes.

CPT Code 98943 covers chiropractic manipulative treatment (CMT) applied to one or more extraspinal regions: any area outside the spine, including the head/neck (non-spinal), rib cage, abdomen, upper extremities, and lower extremities.

Unlike CPT 98940 through 98942, which count spinal regions, 98943 applies once per encounter whenever at least one extraspinal region is manipulated. Treating all five in the same visit isn’t required.

This guide covers region definitions, ICD-10 pairing, Medicare non-coverage, fee schedule data, documentation requirements, and common denial patterns for chiropractic billers and practice managers, including how chiropractic practice management software can flag this distinction at the point of code selection instead of after a claim comes back denied.

The American Medical Association (AMA) maintains the CPT code set, and 98943 sits within the Chiropractic Manipulative Treatment (CMT) family alongside 98940, 98941, and 98942. Code selection within this family comes down to one distinction: whether the regions treated are spinal or extraspinal.

CPT Code 98943: Definition and clinical description

CPT Code 98943 is defined as: Chiropractic manipulative treatment (CMT); extraspinal, 1 or more regions. It is billed once per encounter whenever one or more of the five extraspinal regions are treated. All five do not need to be treated in the same visit for the code to be reportable.

Treating even a single extraspinal region in an encounter supports 98943; the code is not tiered by how many of the five regions were treated. Billers sometimes confuse the extraspinal code with the spinal region counts in the 98940 family, where the number of regions treated determines which of 98940, 98941, or 98942 applies.

They are separate systems entirely. Mixing them is a common miscoding error in chiropractic billing and a leading trigger for payer audits.

The five extraspinal regions covered by CPT Code 98943

CPT Code 98943 applies when one or more of the following extraspinal regions were manipulated during the visit; treating all five in the same encounter is not required. Each region has a distinct anatomical scope.

A key documentation note: the SOAP record must reference each region separately. A single line stating “extraspinal manipulation performed” is insufficient. Payers expect region-specific clinical findings, such as a positive anterior pelvic tilt finding supporting abdominal or pelvic-region treatment, plus the treatment applied and patient response. The documentation burden for CPT Code 98943 is notably higher than for the spinal CMT codes.

CPT 98943 vs. 98940, 98941, and 98942: Choosing the right code

The CMT code family runs from CPT 98940 through 98943. The first three codes count spinal regions (cervical, thoracic, lumbar, sacral, and pelvic). CPT Code 98943 stands apart: it never applies to spinal manipulation. Billing the wrong code from this family is one of the most cited errors in chiropractic audits. The comparison below clarifies when each code is correct.

One scenario worth flagging: a chiropractor treats three spinal regions and four extraspinal regions in the same visit. The correct billing would be CPT 98941 (for the spinal work) alongside CPT Code 98943 (for the extraspinal work); four extraspinal regions alone already supports 98943, since the code only requires one or more regions, not all five.

Only the spinal portion qualifies for Medicare. The extraspinal portion must be billed separately to commercial payers only, or handled as a self-pay service.

Documentation requirements for billing CPT Code 98943

Claim denials for CPT Code 98943 are rarely about code selection. They are almost always about documentation. The claims management software your practice uses should flag incomplete SOAP notes before a claim is submitted, not after it returns denied. Here is what payers expect to see in the clinical record for each 98943 encounter.

• Chief complaint and history: Patient-reported symptoms for each extraspinal region treated. Generic “extremity pain” is insufficient; document which extremity, how long, and severity.
• Examination findings: Objective findings per region, such as range of motion, palpatory findings, or orthopedic test results like Phalen’s test for the wrist or Gaenslen’s test for the pelvis. Each region treated needs its own examination notation.
• Diagnosis with ICD-10 linkage: An ICD-10 code tied to each region treated. A spinal ICD-10 code does not justify extraspinal manipulation. Region-specific diagnosis codes are required.
• Treatment plan and medical necessity: Why extraspinal manipulation is clinically appropriate for this patient at this visit. “Patient requested” is not medical necessity.
• Treatment rendered per region: Document which manipulation technique was applied to which region, including force level or technique type where clinically relevant.
• Patient response: Immediate outcome notation (“tolerated well,” “decreased pain on movement post-treatment”) supports ongoing medical necessity.

Using intake and SOAP forms that are pre-structured for CMT documentation reduces the risk of missing a required field. A chiropractic intake form template that maps directly to the five extraspinal regions ensures clinical staff capture every piece of documentation payers require before the encounter ends.

Practices relying on free-text SOAP notes face far higher denial rates on extraspinal claims than those using structured templates.

Documentation requirements vary slightly by payer. Some commercial carriers add prior authorization requirements for extraspinal CMT; others require a treatment plan signed at the start of a care episode. Always verify payer-specific rules before the first visit.

HIPAA-compliant claim submission also requires that all documentation supporting the claim be stored securely and retrievable for audit within 30 days of a records request.

ICD-10 codes to pair with CPT Code 98943

Every CPT Code 98943 claim requires ICD-10 diagnosis codes that justify extraspinal manipulation for each region treated. Using a spinal diagnosis code (such as M54.5 for low back pain, which is now retired) to support an extraspinal claim will trigger an automatic edit at most clearinghouses.

The table below covers the most commonly paired ICD-10 diagnosis codes, grouped by extraspinal region. For a broader overview of ICD-10 pairing logic across chiropractic visit types, see M99.01, which covers cervical dysfunction and subluxation documentation.

ICD-10 pairings must reflect clinical findings, not be selected to match the CPT code. Payer audits on CPT Code 98943 specifically look for mismatched diagnosis-to-region linkages. If the shoulder region was treated for rotator cuff syndrome, M75.1 must appear on the claim and must be supported by examination findings in the SOAP note.

A region treated without a corresponding ICD-10 code on the claim is an incomplete claim, and most clearinghouses will reject it before it reaches the payer.

Medicare coverage for CPT Code 98943

Medicare does not cover CPT Code 98943. This is a firm exclusion, not a coverage limitation subject to medical necessity overrides. The Centers for Medicare and Medicaid Services (CMS) covers only spinal chiropractic manipulative treatment for the correction of a subluxation.

Extraspinal CMT falls entirely outside Medicare’s chiropractic benefit. Billing Medicare for 98943 will result in automatic denial. Worse, a pattern of Medicare billing for non-covered services can trigger a compliance review.

The practical workflow issue this creates: a Medicare patient often presents for a visit that includes both spinal and extraspinal manipulation. The spinal portion (billed under CPT 98940, 98941, or 98942 as appropriate) may be covered. The extraspinal portion is not. Two paths exist for handling this correctly.

• Bill Medicare for the spinal code only. Document the extraspinal work in the clinical record but do not submit it on the Medicare claim. Some practices collect the extraspinal portion as a separate self-pay charge with an Advance Beneficiary Notice (ABN).
• Issue an Advance Beneficiary Notice (ABN). Before providing extraspinal CMT to a Medicare patient, obtain a signed ABN acknowledging that Medicare will not cover this service and the patient accepts financial responsibility. Without an ABN, the practice cannot bill the patient for the non-covered service.

Commercial payers vary significantly. Blue Cross Blue Shield plans, Aetna, Cigna, and UnitedHealthcare often cover extraspinal CMT under chiropractic benefits, but coverage depends on the specific plan, state, and employer group contract. Always verify benefits before providing extraspinal manipulation to any patient.

CPT 98943 reimbursement rates and fee schedule 2025-2026

Because Medicare does not cover CPT Code 98943, there is no Medicare national rate to cite as a benchmark. Reimbursement comes entirely from commercial payers, and rates vary substantially by plan, state, and contract tier.

The figures below represent general commercial market ranges as reported by fee schedule data sources. Per the CMS Physician Fee Schedule, the Medicare non-facility rate for comparable CMT codes provides a useful floor reference, though 98943 commercial rates typically exceed the spinal CMT Medicare rates.

Use FastRVU’s 2026 RVU lookup to cross-check work RVU values for the CMT family when negotiating commercial payer contracts.

These ranges are market estimates. Specific rates depend on your contract and geographic market. Always verify your contracted rate directly with each payer before assuming a reimbursement figure. Practices that have not renegotiated their commercial contracts in the past three years are often leaving money on the table relative to current market rates for extraspinal CMT.

Common billing errors with CPT Code 98943 and how to avoid them

The errors below account for the majority of CPT Code 98943 denials and audit flags. Each one is preventable with the right workflow. Chiropractic billing consultants consistently identify these five as the highest-risk patterns in extraspinal CMT billing.

1. Assuming 98943 requires all five extraspinal regions. It doesn’t. CPT 98943 is billed once per encounter whenever one or more extraspinal regions are treated. Billers who wrongly withhold the code until all five regions are manipulated in the same visit under-bill legitimate encounters. Confirm the code applies whenever at least one extraspinal region was treated, and document that region’s findings and ICD-10 linkage.
2. Confusing spinal and extraspinal region counts. Billers sometimes assume that because CPT 98941 and 98942 count spinal regions (3-4 and 5, respectively), CPT 98943 must follow the same region-count logic. It doesn’t: 98943 is a single code that applies whenever one or more extraspinal regions are treated, not a region-count ladder. If the visit involved spinal manipulation, use 98940 through 98942 based on how many spinal regions were treated. Use 98943 whenever any extraspinal region was treated.
3. Billing Medicare for CPT Code 98943. As covered above, Medicare excludes this service entirely. A claim submitted to Medicare for 98943 will deny, and a pattern of submission can raise audit flags. Verify payer before billing.
4. Missing ICD-10 linkage for each region treated. A claim for 98943 with a single ICD-10 code for one region while five regions were treated is incomplete. Every region requires clinical justification in both the SOAP record and the claim’s diagnosis pointer fields.
5. Insufficient SOAP documentation for medical necessity. Payers reviewing extraspinal CMT claims look for documentation that explains why each region treated required manipulation on this visit. Vague entries like “patient presented for chiropractic care” do not establish medical necessity. Region-specific findings are non-negotiable.

The common thread across all five errors is documentation that does not match the claim. Whether it is a region count, a diagnosis linkage, or a medical necessity statement, the fix is building structured documentation habits before the claim is generated, not correcting errors after denial.

How practice management software streamlines CPT Code 98943 billing

Chiropractic practices billing CPT Code 98943 regularly face a documentation burden that manual workflows handle poorly. Up to five possible regions, a matching ICD-10 linkage for each region treated, and medical necessity for each creates real complexity at the point of encounter. Practice management workflows built for CMT billing reduce this complexity at every step.

Pabau’s claims management tools and automated billing workflows give chiropractic practices a structured path from SOAP note to clean claim submission.

Client records and notes are structured to capture region-specific findings, and AI-assisted clinical documentation helps practitioners generate compliant SOAP notes without adding time to the encounter. Specific capabilities relevant to 98943 billing include:

• Structured CMT templates: Pre-built SOAP note templates for extraspinal encounters that prompt documentation for each of the five regions, reducing the risk of missing a region-specific finding.
• ICD-10 code suggestion: Integrated diagnosis code tools that surface region-appropriate ICD-10 codes based on the documented chief complaint and examination findings.
• Pre-submission claim review: Automated checks that flag claims missing required diagnosis-to-service linkages before submission, reducing first-pass denial rates.
• Payer-specific rule sets: Configurable billing rules that flag Medicare patients receiving 98943 and prompt staff to generate an ABN or route to self-pay before the claim is built.
• Audit trail documentation: Every clinical entry timestamped and stored in a HIPAA-compliant record, accessible within seconds for payer records requests.

For practices seeing a meaningful volume of extraspinal CMT visits, the ROI on structured billing software shows up in reduced denial rates, faster resubmission cycles, and fewer write-offs from missing documentation. Manual workflows for CPT Code 98943 create backlogs that delay cash flow.

Related chiropractic CPT codes and crosswalks

CPT Code 98943 is rarely billed in isolation. Most chiropractic visits involving extraspinal manipulation also include therapeutic modalities or manual therapy techniques that bill under separate codes. Below are the most commonly co-billed CPT codes, along with crosswalk notes relevant to 98943 encounters.

For a broader reference on chiropractic and allied-health CPT billing guides, Pabau’s procedure code library covers the full range of codes relevant to clinical practice management.

The National Correct Coding Initiative (NCCI) edits published by CMS govern what can and cannot be billed together. While NCCI edits are technically Medicare rules, most commercial payers adopt similar bundling logic. Check the AAPC Codify CPT lookup for modifier applicability and bundling rules before co-billing any therapeutic modality with CPT Code 98943.

Conclusion

CPT Code 98943 is a high-value chiropractic billing code with a specific reporting rule: it is billed once per encounter whenever one or more extraspinal regions are manipulated and documented, not only when all five are treated.

The Medicare exclusion and the region-specific documentation burden make this one of the more error-prone codes in chiropractic billing, but the errors are predictable and preventable.

Pabau’s structured SOAP templates, ICD-10 crosswalk tools, and pre-submission claim review are built to handle exactly this kind of complexity, so chiropractic billing teams spend less time correcting denials and more time on patient care. The same structured approach applies across allied musculoskeletal specialties, including physical therapy software that co-bills modality codes alongside CMT.
