One of the most misunderstood tasks chiropractors face on a daily basis is how to correctly report the segments adjusted during a patient encounter and the use of the appropriate CPT code on a 1500 form for reimbursement. 

The issue at the heart of the matter is the confusion that surrounds the use of the different 9894X series codes (Chiropractic Manipulative Therapy/Adjustment) and how they should be reported to the insurance company versus how they relate to the exact service that was performed. 

There are three major issues to tackle in order to report these codes correctly: 

First, we must understand where transitional areas belong in this whole process. When these areas or regions are adjusted, they must fall into the following classifications that are written in the CPT Manual: 

• The cervical spine includes the atlanto-occipital area. 
• Meanwhile, the thoracic spine includes the costovetebral and costotransverse areas (rib heads). 
• And, the sacral region includes the coccyx. Neither of these areas are considered an extra spinal and if adjusted, don’t qualify as a 98943 or extra spinal adjustment. 

Second, when choosing a CMT code, we must properly report the correct number of areas. Compliant coding of the CMT code would follow these guidelines; 98940 one–two areas or regions, 98941 three-four areas or regions, 98942 five areas or regions. 

Because of the use of regions or areas, one of the main points of confusion is when the doctor reports the number of “segments or vertebra” adjusted versus the correct number of areas. 

For example, the doctor adjusted C1, C3, C5, C7 and T4. This patient encounter would be properly reported as a 98940 because the five spinal adjustments would have taken place in only two regions. The most common of all coding mistakes takes place when the doctor reports this patient encounter as a 98942. This is because the 98942 code requires at least one adjustment to take place in each of the five areas or regions of cervical, thoracic, lumbar, sacrum and pelvis. 

Third, we must be aware that the way chiropractors report an adjustment to the sacral-iliac joint has been under increased scrutiny by auditors over the last few years. To make it easy, remember this rule when an adjustment is given in the low back area: 

• If the joint surfaces between the sacrum and 5th lumbar are moved, it’s to be considered a sacral region adjustment for CPT reporting purposes. 
• If the joint surface between sacrum and illium are moved it’s a pelvic region adjustment for CPT reporting purposes. 
• Therefore, the SI joint adjustment does not qualify as a two area or region adjustment because only one joint surface has been put into motion. 

In the end, why do these 3 issues matter? Because the most common reason a practice gets audited is the frequency with which you use certain codes. If you don’t know exactly how to use each code, you run the risk of finding yourself in a very costly and problematic situation – for you and your practice.
