The extraspinal adjustment code, covering chiropractic manipulative treatment of regions outside the spine: head, upper and lower extremities, rib cage, and abdomen.
The code for the shoulder, wrist, knee, ankle, and TMJ work many chiropractors do alongside spinal care. It can be billed with a spinal CMT code on the same visit when both were performed and documented. Commercial coverage varies widely; some plans cover it like spinal CMT, others exclude extraspinal work entirely.
A runner with a documented lumbar complaint also has a restricted ankle treated the same visit. 98941 would overstate the spine work; the honest claim is 98940 for the lumbar and sacral findings plus 98943 for the ankle, each pointed at its own diagnosis. Point the ankle line at the lumbar diagnosis instead and the extraspinal line denies for diagnosis mismatch.
Medicare limits chiropractor payment to manual manipulation of the spine to correct a subluxation, per the Benefit Policy Manual, Chapter 15, section 240. Extraspinal manipulation is outside the benefit entirely, which is a statutory wall rather than a documentation problem.
Not covered. Medicare pays chiropractors for spinal manipulation only, so 98943 is excluded by statute regardless of documentation. With proper patient notice it is billable to the patient at the practice rate.
Pointing the extraspinal line at a spinal diagnosis; assuming commercial coverage without checking the plan; billing it to Medicare expecting payment.
Cervica's claim scrubber validates modifiers, units, and diagnosis pointers for 98943 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.
