Is ultrasound therapy covered by insurance?
Often yes, for a limited stretch of care. Code 97035 is the ultrasound head moved over sore tissue to warm it below the skin, counted in 15 minute blocks with the provider in the room the whole time. Plans pay it while the treatment plan is active and stop once the notes start to look like maintenance.
Often
Covered short term with an active plan
8 minute floor
Ultrasound is timed. Under eight minutes of treatment most payers allow no unit at all, and the minutes have to be written in the note.
Stay in the room
The code assumes the provider stays with the patient for the whole treatment. A device left running alone falls to an unlisted code that pays little.
Short term only
Payers expect passive modalities to taper as active care takes over. Week ten of the same ultrasound is where the denial letters start.
Check the modality
Modality benefits can differ from adjustment benefits on the same card. Running the benefit first shows plan status, the deductible left and the coinsurance the payer reports.

Pick a sample plan and type your per-unit fee. This is the visibility a real-time check gives the desk for every actual patient, in under a second.

Estimate from a sample plan. A real check reads the actual plan in under a second.
When 97035 is the right code
- The provider is with the patient the whole time
- At least eight minutes of treatment time
- Applied to the region named in the diagnosis
- Part of an active plan that is making progress
- Not a device left running on its own
Documentation payers expect
Payers expect the minutes, the region, the settings and a diagnosis that matches, plus progress notes showing the passive work shrinking as active care grows. Repeat weeks with flat notes are the ones that get pulled.
Why ultrasound therapy gets denied
What happens as the plan of care moves on
Ultrasound is a starter, not a program. Within a few weeks most payers expect the claim to shift toward active care such as 97112, and each of those visits still burns a slot in the annual chiropractic cap. When the cap runs out mid plan, the rest of the schedule becomes cash, usually discovered at the front desk. Running the check before care starts shows plan status, the deductible left and the copay while the plan of care can still be built around real numbers.
97035, quick answers
Does insurance cover ultrasound therapy?
Most plans cover 97035 for a limited stretch when it is part of an active treatment plan with documented progress. Some exclude passive modalities from the chiropractic benefit entirely.
Does Medicare pay a chiropractor for ultrasound?
No. The Medicare chiropractic benefit covers the spinal adjustment only, so 97035 is not payable from a chiropractor. A physical therapist or physician can bill it under a plan of care.
How many units can be billed in a visit?
Timed units follow the minutes actually spent, and most plans allow only one or two timed units per visit. The daily cap is a plan rule that varies by payer.
Can ultrasound be billed with the adjustment?
Usually yes, since it is a modality rather than hands-on therapy, but the region and diagnosis have to support both lines on the same claim.
What if the machine runs without the provider?
Then 97035 is not the right code. Unattended use falls to the unlisted modality code 97039, which most plans pay very little for or do not pay at all.
