98941: Chiropractic manipulative treatment, spinal, three to four regions
Category: Spinal CMT
By Dr. Daniel Turner, DC · Reviewed September 2, 2026
What is 98941 used for?
The middle spinal adjustment code, for chiropractic manipulative treatment addressing three or four of the five spinal regions in one visit.
How it works in a chiropractic practice
The most billed CMT code in many practices, and the most audited, precisely because it pays more than 98940 and the difference is documentation. Every region counted needs its own documented subluxation findings and treatment. A full spine check is not four regions of treatment; four regions of documented findings and applied manipulation is.
What the note must show
- ✓Findings and treatment for each of the three or four regions claimed, region by region
- ✓Diagnoses on the claim covering the regions billed, correctly pointed from the service line
- ✓For Medicare, the subluxation requirement and AT modifier, as with all spinal CMT
A worked example
A patient with low back pain also carries documented cervical and thoracic subluxation findings, all three regions adjusted and noted. 98941 is correct. Six months later the cervical complaint has resolved and stopped appearing in the note, but the code never stepped back down to 98940. That drift, region count outliving the findings, is exactly what payer algorithms flag.
Billing 98941 with other codes on the same visit
- ✓Untimed, one unit, and mutually exclusive with 98940 and 98942; the region count picks exactly one CMT code per visit
- ✓The same 97140 bundling and modifier rules as 98940, with less room for a distinct region since three or four are already claimed by the CMT
- ✓Therapy codes on the same claim should point at diagnoses covering their own treated areas, not ride the CMT diagnosis list
Does Medicare pay chiropractors for 98941?
Covered under the same rules as 98940. Region support matters more here: reviewers compare the region count implied by the code against the regions actually documented, visit by visit.
Where practices get burned
Code never stepping down as complaints resolve; identical region counts on every visit for months, which reads as templated rather than clinical; missing per region findings.
How Cervica helps with 98941
Cervica's claim scrubber validates modifiers, units, and diagnosis pointers for 98941 before submission, per payer rules handle code substitutions and modifier requirements automatically, and when a payer pushes back anyway the denial worklist reads the adjustment codes and routes the claim to the exact fix.
