Is an extremity adjustment covered by insurance?
It depends, and often the answer is no. Many chiropractic benefits cover the spine and nothing else, so a shoulder, knee, elbow or jaw adjustment is denied outright or paid only when a spinal adjustment is billed the same day. Code 98943 is the adjustment for joints outside the spine.
Often no
Many plans cover the spine only
Medicare: never
Medicare's chiropractic benefit stops at the spine, so this is excluded by law. Bill it with modifier GY and the patient owes it, signed notice or not.
Spine-only riders
A large share of chiropractic benefits list spinal adjustments only. The joint line denies while the spinal adjustment on the same claim pays normally.
Paired or nothing
Some payers pay 98943 only when a spinal adjustment sits on the same date of service. Alone on a claim, it is the easiest denial they write.
Cash or claim
This is the code most likely to become a cash line. One check at intake shows plan status and tests the joint service type against the plan.

When 98943 is the right code
- A joint outside the spine was adjusted
- Findings and a diagnosis for that joint
- The plan covers adjustments outside the spine
- Billed with the spinal adjustment where required
- Active treatment, not a wellness visit
Documentation payers expect
The note names the joint, the findings and the reason for treating it that day. For Medicare patients the charge is theirs by law, so flag the line as excluded and quote the price up front.
Why extremity adjustments get denied
What happens when the joint line denies
The spinal adjustment pays, the 98943 line denies, and the patient gets a bill for something they thought was part of the visit. Collecting it goes better when the price was quoted before the treatment rather than mailed after it, and for Medicare patients the charge is theirs by law even without a signed form. Checking plan status and testing the service type against the plan first turns that surprise into a ten second conversation at check-in.
98943, quick answers
Is an extremity adjustment covered by insurance?
It varies more than any other chiropractic code. Many plans cover spinal adjustments only, and those plans deny 98943 no matter how good the note is.
Does Medicare cover 98943?
No. Medicare covers only manual adjustment of the spine from a chiropractor, so a joint adjustment is always the patient's cost, whether or not anything was signed.
Can it be billed with a spinal adjustment?
Yes, and many payers only pay it that way, on a date that also carries 98940, 98941 or 98942.
Does it count against the visit limit?
The visit does. Billing both codes on one date is still one visit against the plan's chiropractic cap.
Why did my shoulder cost money when my back did not?
The plan most likely covers spinal adjustments only, so the spinal line paid and the joint line landed on you.
