Does Medicare cover chiropractic adjustments?
Usually yes. Medicare pays for spinal adjustments as long as the visit is active treatment for a diagnosed spine problem, and it stops paying the day that care turns into upkeep. Code 98941 is the adjustment that treats three or four of the body's five spinal areas at one visit, the workhorse adjustment in most chiropractic offices.
Usually
Covered when care is active treatment
AT or nothing
Medicare reads a 98941 claim with no AT modifier as maintenance and denies it. That one modifier is the whole difference between paid and a patient bill.
3 to 4 areas
98941 covers three or four spinal areas. One or two is 98940 and all five is 98942, and payers audit offices that drift upward between them.
12 to 30 visits
Most commercial plans cap chiropractic somewhere in that range each year, shared across every adjustment code. The visit past the cap belongs to the patient.

- Active treatment aimed at a measurable change
- A diagnosis naming each area being treated
- AT modifier on the claim for Medicare
- A dated plan of care with goals
Documentation payers expect
Payers expect the areas treated, the exam findings behind each one, and progress notes showing function improving, not just pain easing. Medicare also wants the initial treatment date and a plan of care on file.
Why 98941 gets denied
What happens when the visits run out
Most plans set one yearly chiropractic allowance and let 98940, 98941 and 98942 all draw on it. When it empties mid plan of care the visits do not stop, the bill just moves to the patient or turns into a cash maintenance visit (S8990). Offices that never have that argument watch the count and say the number out loud early, which starts with checking the plan before the first visit.
98941, quick answers
Does Medicare cover chiropractic adjustments?
Medicare covers spinal adjustments when they are active treatment for a diagnosed spine problem and the claim carries the AT modifier. Upkeep visits are not covered.
How many visits will a plan pay for?
It varies a lot, and many commercial plans land somewhere between 12 and 30 chiropractic visits a year across every adjustment code. A check before the visit shows plan status and the cost share the payer reports.
What is the difference between 98940 and 98941?
The number of spinal areas worked on. 98940 is one or two, 98941 is three or four, and the note has to support the count.
Does Medicare pay for the exam and X-rays too?
No. Medicare's chiropractic benefit is the spinal adjustment by hand, so exams, X-rays and therapy from a chiropractor are the patient's bill.
Do adjustments need prior authorization?
Some plans want a treatment plan approved after the first handful of visits, and some HMOs want a referral on file. Where the payer reports a referral or authorization flag, the check surfaces it before you schedule.
