What 98941 covers
A chiropractor manipulates three or four of the five spinal regions: cervical, thoracic, lumbar, sacral, and pelvic. Treatment usually occurs in an office and may use hands-on, instrument-assisted, or drop-table techniques. A visit treating documented subluxations in the cervical, thoracic, and lumbar regions is an example. Count regions treated, not individual vertebrae adjusted or sides of the spine.
Document the subluxation, supporting findings, and manipulation for each counted region. Medicare covers a chiropractor’s manual spinal manipulation to correct subluxation when the subluxation is established by X-ray or physical examination. A physical examination must document at least two PART findings, including asymmetry or restricted range of motion. Use modifier AT for active or corrective treatment; Medicare treats claims without AT as maintenance care and denies them. The 0-day global period includes routine same-day preoperative and postoperative care. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

98941 billing questions
How do I choose between 98940, 98941, and 98942?
Count the distinct spinal regions manipulated and supported by documented subluxations. Use 98940 for one or two regions, 98941 for three or four, and 98942 for all five.
Is the AT modifier required on 98941 for Medicare?
Use AT when the manipulation is active or corrective treatment. Medicare treats a chiropractic manipulation claim without AT as maintenance care and denies it.
Can an E/M visit be billed on the same day as 98941?
Medicare does not cover E/M services furnished by chiropractors, even with modifier 25. For a payer that covers the E/M service, a significant, separately identifiable visit may be reported with modifier 25 on the E/M code; routine assessment around the manipulation is included.
What documentation supports each region counted?
Identify the subluxation and supporting findings for each region, and record the manipulation performed there. For Medicare, a physical examination used to establish subluxation must include at least two PART findings, one of which is asymmetry or restricted motion.
Does Medicare pay for extraspinal manipulation done at the same visit?
Medicare does not cover extraspinal chiropractic manipulation under 98943. Another insurer may cover 98943 alongside 98941 when both spinal and extraspinal regions are treated.
Should modifier 50 be used if both sides of the spine are adjusted?
No. Select 98941 by the number of spinal regions manipulated, not by laterality; modifier 50 is inappropriate.
