CPT Codes 98940, 98941 & 98942 for Chiropractic Billing: Complete 2026 Guide

Chiropractic billing has changed significantly over the last few years. In 2026, providers are dealing with stricter insurance rules, more documentation reviews, rising audit activity, and increasing pressure to improve claim accuracy.

Insurance verification companies now use advanced technology to review chiropractic claims. Medicare contractors are closely monitoring billing patterns. Commercial payers are flagging coding mistakes much faster than before.

Because of this, even small billing errors can create serious problems.

Incorrect coding may lead to:

• Claim denials
• Delayed payments
• Compliance issues
• Audit risks
• Revenue loss
• Increased accounts receivable

At Practolytics, we work closely with chiropractic clinics and healthcare providers across the United States. Our goal is simple. We help practices improve reimbursement accuracy, reduce denials, and strengthen revenue cycle performance.

Most guides do not explain:

• Medicare compliance rules
• AT modifier requirements
• Documentation expectations
• ICD-10 diagnosis pairing
• E/M billing rules
• Denial prevention strategies
• Chiropractic audit risks
• Revenue cycle management workflows

This guide was created to solve that problem.

We designed this article specifically for:

• Chiropractors
• Healthcare providers
• Medical billing teams
• Revenue cycle managers
• Practice administrators
• Medical coders
• Multi-specialty healthcare organizations

Our goal is to provide a professional yet easy-to-understand resource that helps healthcare providers improve chiropractic billing performance in 2026.

What Are CPT Codes 98940–98942? (Chiropractic Manipulative Treatment Defined)

CPT 98940, CPT 98941, and CPT 98942 are used to report chiropractic manipulative treatment codes involving spinal manipulation. These codes are a major part of CMT billing and are based on the number of spinal regions treated during the visit.

The spine is divided into five recognized regions for chiropractic billing purposes.

The Five Spinal Regions

Spinal Region	Description	Common Patient Complaints
Cervical	Neck area	Neck pain, headaches, stiffness
Thoracic	Mid-back	Upper back pain, posture issues
Lumbar	Lower back	Lower back pain, mobility problems
Sacral	Base of spine	Sacroiliac pain, stiffness
Pelvic	Pelvic joint region	Hip imbalance, pelvic instability

CPT Code Breakdown

CPT Code	Regions Treated	Typical Billing Scenario
CPT 98940	1–2 spinal regions	Mild or localized dysfunction
CPT 98941	3–4 spinal regions	Multi-region spinal treatment
CPT 98942	5 spinal regions	Full spine manipulation

Correct spinal region selection is extremely important in spinal manipulation billing.

Insurance companies now use automated claim-review systems to identify:

• Overcoding
• Excessive treatment frequency
• Unsupported region counts
• Repeated full spine adjustment code billing

At Practolytics, we regularly help providers identify these problems early before they affect reimbursements.

CPT Code 98940: Spinal Manipulation of 1–2 Regions

CPT 98940 is used when the chiropractor performs manipulation involving one or two spinal regions.

This is one of the most common chiropractic adjustment CPT code selections in outpatient chiropractic care.

Providers often use this code when treating:

• Mild neck pain
• Lumbar discomfort
• Limited spinal dysfunction
• Muscle tightness
• Minor posture problems
• Acute back pain

In many chiropractic clinics, this code is commonly used during routine follow-up visi

CPT 98940 — Clinical Scenarios, Documentation Requirements & Reimbursement Rates

Strong documentation is essential when billing CPT 98940.

The medical record should clearly explain:

• Patient symptoms
• Functional limitations
• Examination findings
• Subluxation details
• Regions treated
• Treatment goals

Example Clinical Scenario

A patient visits the clinic with:

• Neck stiffness
• Mild lower back pain
• Difficulty sitting for long periods

The chiropractor performs:

• cervical spinal manipulation
• Lumbar spinal adjustment

Since only two spinal regions were treated, the correct code is CPT 98940.

Documentation Requirements

The documentation should include detailed SOAP notes.

Subjective Findings

The subjective section should include:

• Pain severity
• Patient complaints
• Functional limitations
• Symptom duration

Objective Findings

The objective section should include:

• Muscle tightness
• Restricted motion
• Palpatory findings
• Orthopedic test results

Assessment

The assessment section should include:

• Diagnosis
• Subluxation findings
• Progress evaluation

Plan

The plan section should include:

• Treatment frequency
• Follow-up schedule
• Expected improvement goals

Weak documentation is one of the biggest reasons for Medicare chiropractic denial cases involving CPT 98940.

CPT Code 98941: Spinal Manipulation of 3–4 Regions

CPT 98941 applies when chiropractic treatment involves three or four spinal regions.

This is commonly called the 3-4 spinal regions CPT code.

Providers often use this code for patients with:

• Sports injuries
• Chronic back pain
• Multi-region dysfunction
• Postural imbalance
• Motor vehicle accident injuries
• Widespread muscular tightness

This code requires careful documentation because insurance companies review higher-level spinal manipulation codes more closely.

CPT 98941 — When to Use It, ICD-10 Pairs & Medicare Coverage

Providers should bill CPT 98941 only when documentation clearly supports treatment involving three or four spinal regions.

Example Scenario

A patient reports:

• Neck pain
• Thoracic tightness
• Lower back discomfort
• Pelvic instability

The chiropractor performs manipulation involving:

• Cervical region
• Thoracic region
• Lumbar region
• Pelvic region

This supports CPT 98941 billing.

Common ICD-10 Diagnosis Pairings

Correct diagnosis coding is critical in chiropractic billing. The following chiropractic diagnosis codes ICD-10 are commonly paired with chiropractic manipulation services.

ICD-10 Code	Description
ICD-10 M99.00 subluxation	Segmental dysfunction
M99.01	Cervical dysfunction
M99.02	Thoracic dysfunction
M99.03	Lumbar dysfunction
M99.04	Sacral dysfunction
M99.05	Pelvic dysfunction
M54.2	Neck pain
M54.5	Low back pain

Correct diagnosis pairing supports:

• Medical necessity
• Claim approval
• Better compliance
• Reduced denials

Under Medicare chiropractic coverage, spinal manipulation is covered only when active treatment is provided.

Maintenance therapy is generally not covered.

CPT Code 98942: Full-Spine Manipulation (5 Regions) — Rules & Risks

CPT 98942 is used when all five spinal regions are treated during the visit. This code carries the highest audit risk among all chiropractic billing codes. Insurance companies carefully monitor repeated use of 5 spinal regions billing because it may indicate overcoding if documentation is weak.

Payers often review:

• Billing frequency
• Medical necessity
• Documentation quality
• Treatment consistency
• Region accuracy

Improper use of this full spine adjustment code may trigger:

• Claim reviews
• Prepayment audits
• Post-payment audits
• Refund requests
• Compliance investigations

CPT 98942 — Documentation Checklist to Avoid Upcoding Audits

Detailed documentation is extremely important for CPT 98942.

The medical record should clearly document findings for:

• Cervical region
• Thoracic region
• Lumbar region
• Sacral region
• Pelvic region

Strong Documentation Should Include

Required Documentation Element	Why It Matters
Functional limitations	Supports medical necessity
Pain assessment	Justifies treatment need
Motion restriction findings	Demonstrates dysfunction
Muscle tightness	Supports treatment rationale
Neurological findings	Strengthens documentation
Progress notes	Shows active treatment

Avoid vague statements like:

• “Patient adjusted”
• “Routine treatment performed”
• “Full spine treated”

These statements usually do not meet payer documentation standards.

At Practolytics, we regularly help practices improve documentation workflows to reduce audit risks involving vertebral subluxation billing.

Modifier AT: The Critical Medicare Requirement for 98940–98942

The AT modifier chiropractic requirement is one of the most important Medicare compliance rules for chiropractors.

The AT modifier tells Medicare that the treatment is:

Active treatment designed to improve the patient’s condition.

Without this modifier, Medicare may treat the service as maintenance therapy and deny the claim.

Active Treatment vs. Maintenance Therapy — What the AT Modifier Means?

Providers must clearly understand the difference between active treatment and maintenance therapy.

Active Treatment

Active treatment is care intended to:

• Reduce pain
• Improve mobility
• Restore function
• Correct dysfunction

Examples include:

• Injury recovery
• Acute pain management
• Functional rehabilitation

Maintenance Therapy

Maintenance therapy usually involves:

• Wellness care
• Preventive adjustments
• Routine spinal maintenance

These services are generally not covered under Medicare chiropractic coverage.

Improper modifier AT active treatment usage is a major cause of:

• Claim denials
• Payment recoupments
• Medicare audits

ICD-10-CM Diagnosis Codes That Support 98940–98942 Billing

Correct diagnosis coding is essential for successful reimbursement.

Most chiropractic claims use subluxation diagnosis codes as the primary diagnosis.

Common Subluxation Codes

ICD-10 Code	Description
M99.00	Segmental dysfunction
M99.01	Cervical region dysfunction
M99.02	Thoracic dysfunction
M99.03	Lumbar dysfunction
M99.04	Sacral dysfunction
M99.05	Pelvic dysfunction

These diagnoses support vertebral subluxation billing requirements.

Primary Subluxation Codes (M99.00–M99.05) and Secondary Symptom Codes

Secondary diagnoses strengthen medical necessity documentation.

Common Secondary Diagnoses

ICD-10 Code	Description
M54.2	Neck pain
M54.5	Low back pain
M62.830	Muscle spasm
G54.1	Radiculopathy

Accurate diagnosis pairing improves:

• Reimbursement accuracy
• Claim approval rates
• Audit readiness
• Compliance performance

Strong diagnosis coding also supports medical necessity chiropractic requirements.

SOAP Notes & Documentation Best Practices for Chiropractic Claims

Strong chiropractic SOAP notes billing practices are essential for compliance and reimbursement.

Insurance companies expect providers to clearly explain:

• Why treatment is necessary
• What findings support treatment
• How the patient is progressing

Incomplete documentation is one of the biggest causes of chiropractic claim denials.

SOAP Note Structure

Subjective

The subjective section should include:

• Patient complaints
• Pain severity
• Functional limitations
• Symptom changes

Objective

The objective section should include:

• Range of motion findings
• Muscle tightness
• Orthopedic test results
• Neurological findings

Assessment

The assessment section should include:

• Diagnosis
• Subluxation findings
• Progress evaluation

Plan

The plan should include:

• Treatment schedule
• Follow-up visits
• Measurable treatment goals

Detailed SOAP notes improve both compliance and reimbursement performance.

What Auditors Look For: Common Documentation Errors in Chiropractic Billing?

Insurance auditors review chiropractic claims closely for signs of:

• Overutilization
• Unsupported treatment
• Weak documentation
• Upcoding

Common Documentation Errors

Documentation Problem	Potential Risk
Missing spinal regions	Claim denial
Repetitive SOAP notes	Audit risk
Weak objective findings	Medical necessity failure
Unsupported full spine adjustment code usage	Upcoding review
Missing progress documentation	Reimbursement denial

Payers also monitor improper use of:

• extraspinal CPT 98943
• Modifier 25
• E/M services

At Practolytics, our compliance specialists help practices identify documentation gaps before they impact reimbursements.

Billing 98940–98942 With E/M Codes (99202–99215): Rules and Pitfalls

Chiropractors may bill E/M services separately when medically necessary.

Common E/M codes include:

• 99203 99214 chiropractic E/M
• 99202
• 99204
• 99215

However, providers should not bill E/M services for routine chiropractic assessments.

Modifier 25 — When to Append It for Same-Day E/M and CMT

The modifier 25 chiropractic rule applies when a significant separately identifiable E/M service is performed during the same visit.

Appropriate Scenarios

• New patient evaluations
• New injuries
• Neurological symptoms
• Significant condition changes

Common Errors

• Billing routine evaluations
• Missing separate documentation
• Repeating previous evaluations

Improper modifier 25 usage remains a major audit concern.
