Important Chiropractic CPT Codes to know

At Practolytics, we work inside chiropractic billing every single day, and one thing hasn’t changed—coding mistakes cost practices money. Knowing the Important Chiropractic CPT Codes to know helps chiropractors avoid denials, survive audits, and keep cash flow steady. Chiropractic claims face heavier scrutiny than many other specialties, especially for spinal manipulation and evaluations. Even when care is appropriate, unclear documentation or incorrect code selection can slow payments or trigger reviews. In this guide, we break down the chiropractic CPT codes that matter most, explain how payers actually look at them, and share real-world billing insights based on what we see working—and failing—across practices.

From the outside, chiropractic billing looks simple. Same types of visits. Similar treatments. A small group of codes used again and again. But that simplicity is exactly why chiropractic claims are watched so closely by insurance companies.

The Important Chiropractic CPT Codes to know form the backbone of almost every chiropractic claim. These codes tell payers how many spinal regions were treated, whether care is active or maintenance, and whether services were medically necessary on that specific day. A basic chiropractic CPT codes list doesn’t explain how insurers interpret those decisions—and that’s where practices often get caught off guard.

We’ve seen chiropractors deliver excellent care and still struggle with revenue. Not because of overbilling or poor outcomes, but because claims didn’t clearly explain what happened during the visit. At Practolytics, we help practices translate real clinical care into claims that make sense to insurance reviewers—not just billing software.

Why Chiropractic CPT Codes Matter ?

Chiropractic billing has changed. Claims aren’t just processed anymore—they’re analyzed.

Payers track patterns over time. They look at how often patients are treated, how frequently spinal manipulation is billed, and whether documentation evolves as care progresses. The common chiropractic CPT codes used daily are the same ones reviewed during audits and post-payment reviews.

Repeated use of the most used chiropractic CPT codes, especially higher-level spinal manipulation, can raise red flags if notes don’t clearly show progress or changing clinical findings. Even when care is appropriate, repetitive documentation can make it look questionable.

Another factor is automation. Most claims are first reviewed by software, not humans. When chiropractic CPT codes explained through documentation don’t vary—or don’t clearly support medical necessity—claims get flagged automatically. We help practices adjust documentation just enough to reflect real clinical changes without adding extra work.

Understanding CPT Codes in Chiropractic Billing

CPT codes are how payers understand your visit. In chiropractic care, chiropractic billing CPT codes must do more than list services—they must tell a story.

CPT codes for chiropractic services are evaluated alongside:

• Diagnosis codes
  
• Treatment plans
  
• Visit frequency
  
• Duration of care
  
• Patient response over time
  

Many chiropractic treatment CPT codes are denied because the claim doesn’t answer a simple question: Why did the patient need this service today?

One common mistake is treating the chiropractic CPT codes list like a checklist instead of a communication tool. Payers don’t just want to know what you did. They want to know why it mattered at that stage of care. Small documentation gaps here can quietly drain revenue month after month.

Most Important Core Chiropractic Adjustment CPT Codes

Spinal manipulation is the foundation of chiropractic care—and the biggest source of payer scrutiny. The chiropractic adjustment CPT codes you choose must be accurate and well supported.

CPT codes 98940 98941 98942

These are the core spinal manipulation CPT codes chiropractic practices use for chiropractic manipulative treatment (CMT). The difference between them is based solely on the number of spinal regions treated:

• 98940 – 1–2 spinal regions
  
• 98941 – 3–4 spinal regions
  
• 98942 – 5 spinal regions
  

These are the most common CPT codes for spinal adjustments, and also the most audited.

One issue we see often is regional overcounting—billing for more regions than documentation clearly supports. When insurers see this repeatedly, they may automatically downcode CPT codes 98940 98941 98942, sometimes without immediate notice.

Chiropractic manipulation CPT codes require region-specific clarity. Payers expect to see which regions were treated, why each one required care, and how treatment relates to the diagnosis. General phrases like “adjusted spine” rarely hold up during reviews.

Chiropractic Evaluation and Management (E/M) CPT Codes

Evaluation services are allowed in chiropractic care, but they must be clearly distinct. Chiropractic evaluation CPT codes can’t represent routine pre-adjustment checks.

New vs Established Patient Coding

• New patient chiropractic CPT codes apply when the patient hasn’t received professional services from the provider in the past three years.
  
• Established patient chiropractic CPT codes apply to ongoing care.
  

Chiropractic Exam and E/M Services

Chiropractic exam CPT codes and E/M codes for chiropractors must show real clinical decision-making. That includes:

• History
  
• Examination
  
• Assessment changes
  
• Treatment plan adjustments
  

Timing also matters. Payers expect evaluations at logical points—initial visits, re-exams, or significant changes. Billing E/M services without a clear reason often leads to denials. We help practices decide not just how to bill E/M codes, but when it actually makes sense.

Chiropractic Modality CPT Codes

Many chiropractic visits include therapies beyond manipulation. These CPT codes for chiropractic services cover therapeutic exercise, manual therapy, ultrasound, and electrical stimulation.

Most chiropractic treatment CPT codes for modalities are time-based, which means documentation must be precise. Payers expect:

• Actual time spent
  
• Patient participation
  
• Clear therapeutic purpose
  

Vague notes like “tolerated well” don’t support payment. Insurers want to know how the modality addressed the condition and supported the treatment plan. At Practolytics, we often improve reimbursement simply by tightening modality documentation—without changing care delivery.

Conclusion:

Knowing the Important Chiropractic CPT Codes to know isn’t about memorizing code numbers or turning yourself into a billing nerd. It’s really about protecting your practice from unnecessary headaches. You can do everything right clinically and still struggle with payments if your coding or documentation doesn’t clearly explain what happened during the visit.

What we see all the time at Practolytics is chiropractors providing solid care but losing money because the claim didn’t tell the full story. Maybe the regions weren’t clearly listed. Maybe the notes sounded the same visit after visit. Maybe a modifier was missed. On their own, those things seem small. Over time, they add up to denials, delayed checks, or awkward payer reviews.

Our goal is to take that pressure off your plate. We help clean up the billing side so your claims match the care you’re actually giving. When everything lines up, payments come in more consistently, stress drops, and your team can spend more time with patients instead of chasing insurance companies.

What is the primary distinction between CPT codes 98940, 98941, and 98942?

It really comes down to one thing: how many spinal regions you adjusted during the visit. If you worked on one or two regions, that’s 98940. Three or four regions fall under 98941. All five regions get billed as 98942. It has nothing to do with how long the visit took or how complex it felt—just the region count.

What specific spinal regions are considered for these CMT codes?

There are five regions total: cervical, thoracic, lumbar, sacral, and pelvic. Each one counts on its own. When you’re documenting, it helps to be very clear about which regions you treated. Vague notes like “adjusted spine” don’t hold up well when insurers review claims.

Can I bill more than one of the 98940–98942 codes on the same date of service?

No. You can only bill one CMT code per visit. You choose the code based on the total number of regions treated that day. Trying to bill more than one almost always leads to a denial.

What are the key documentation requirements to support a CMT claim?

Keep it simple but clear. Your notes should show why the adjustment was needed, which regions were treated, how it connects to the diagnosis, and how the patient is doing over time. You’re basically telling the story of the visit in a way an insurance reviewer can follow.

When is the -AT modifier required for the CMT codes (98940–98942)?

The -AT modifier is used to show that you’re providing active treatment for an acute or chronic condition. Without it, many payers—especially Medicare—will assume the care is maintenance and deny the claim.
