Are you seeing an uptick in claim denials for your chiropractic services? You aren’t alone. While chiropractic care is surging in popularity—often outperforming traditional medication for back pain relief—the increased volume makes accurate billing more critical than ever.
One of the most common stumbling blocks is CPT Code 98942. Because this code represents a comprehensive, full-spine treatment, insurance payers scrutinize it closely.
Here is a practical guide to understanding when to use CPT 98942 and how to document it to ensure you get reimbursed.
What is CPT Code 98942?
Simply put, CPT 98942 is the procedural code for Chiropractic Manipulative Treatment (CMT) that covers all five spinal regions.
If you are only adjusting one or two areas, this is not the code for you. To use 98942 legitimately, you must have performed manipulation on all five of the following regions during a single session:
- Cervical: The neck (C1-C7).
- Thoracic: The upper/mid back (T1-T12).
- Lumbar: The lower back (L1-L5).
- Sacral: The pelvic region (S1-S5).
- Coccygeal: The tailbone (Coccyx).
When Should You Use CPT Code 98942?
Using 98942 isn’t about trying to bill for a higher rate; it is about medical necessity. Here are common clinical scenarios where a 5-region adjustment is appropriate.
1. Trauma Reactivation (e.g., Old Car Accidents)
Consider a patient who was in a motor vehicle collision years ago. They present with widespread pain flaring up across their entire back. Upon examination, you find subluxations or dysfunction in the neck, upper back, lower back, and hips.
-
Why 98942 applies: To stabilize the spine and address the trauma-related imbalances radiating throughout the body, you must adjust every region from the cervical spine down to the coccyx.
2. Chronic Pain from Sedentary Work
Imagine a 32-year-old remote worker who spends hours working from a laptop in bed or at a non-ergonomic desk. They come in with stiffness in the neck, tightness in the shoulders, and lower back pain that affects their ability to sit.
-
Why 98942 applies: The poor posture has caused a “chain reaction” of misalignment. You find issues in the cervical spine (neck craning), thoracic (hunching), and lumbar/sacral regions (anterior pelvic tilt). Correcting this global postural imbalance requires a full-spine adjustment.
Essential Modifiers for CPT 98942
Modifiers tell the insurance payer the “story” behind the code. Missing these is a top reason for denials.
| Modifier | When to Use It |
| Modifier 59 | Use this to indicate a distinct procedural service. For example, if you perform manual therapy (CPT 97140) or massage (CPT 97124) in a different area than the adjustment on the same day, Modifier 59 tells the payer, “This was a separate service, not just part of the adjustment.” |
| Modifier AT | Crucial for Medicare. This stands for “Active Treatment.” You must append this to show that the care is corrective and medically necessary to improve a condition, rather than just “maintenance care” (which Medicare generally does not cover). |
How to Dodge Denials: 3 Best Practices
Because 98942 claims a high level of intervention, payers want proof that it was necessary.
1. Your Documentation Must Be “Audit-Proof”
If it isn’t written down, it didn’t happen. General notes like “patient feels pain” won’t cut it. Your documentation needs to clearly list:
- Specific findings for ALL five regions: You must document the subluxation or dysfunction found in the cervical, thoracic, lumbar, sacral, and coccygeal areas individually.
- The specific adjustment used for each area.
- The goal: Is this to restore function? Reduce pain?
- Progress: How is the patient responding compared to the last visit?
2. Verify Payer Policies First
Medicare is strict, but private commercial payers (like BCBS or United) have their own rules. Some may have caps on how many times you can bill 98942 in a given period. Always check the patient’s specific coverage guidelines regarding high-level CMT codes.
3. Don’t Forget the AT Modifier for Medicare
If you submit 98942 to Medicare without the AT modifier, their system automatically assumes it is “maintenance therapy” and will deny the claim. If you are actively treating an injury or condition, that modifier is mandatory.
Summary
CPT 98942 is a valuable code for complex cases requiring full-spine attention, but it requires precision. By ensuring you have actually treated all five regions, documenting the specific necessity for each, and applying the correct modifiers, you can stop leaving money on the table and focus on patient care.
