Is cold laser therapy covered by insurance?
Usually no. Medicare and nearly every commercial plan call low level laser unproven, so it is a cash service almost everywhere. S8948 is the code for a timed laser treatment where the provider stays with you, billed in 15 minute blocks. A few plans load it on a fee schedule, but most pay nothing for laser under any code.
Almost never
Low level laser called investigational
Medicare: no code
Medicare does not recognize S8948 at all, so the line rejects rather than denies. There is no version of this that Medicare pays a chiropractor.
Renaming fails
Billing laser as ultrasound or manual therapy to get it paid is not a workaround. It is the kind of thing that surfaces in a payer audit.
A few pay it
Some commercial plans and some auto or work injury carriers keep S8948 on a fee schedule. It is worth asking, but never worth assuming.
Price it as cash
Laser packages sell better with a clean number. A check before the visit shows plan status and the amounts left, so covered work and cash work stay apart.

When S8948 is the right code
- Low level laser applied to one or more areas
- Provider stays with the patient the whole block
- Timed in 15 minute units with minutes noted
- The payer actually loads this S code
- Patient agreed to the cash price up front
Documentation payers expect
Note the device and its class, the areas treated and the exact minutes, and keep the signed financial agreement. For a payer that does take the code, expect a policy review and a records request before anything pays.
Why cold laser therapy is not paid
What happens after the package is sold
Laser is almost always sold as a package, six or twelve visits, and it rides along with covered care like the adjustment or 97140 manual therapy on the same day. The covered lines process, the laser line denies, and the explanation of benefits arrives showing both. That is the call the desk gets. Some patients then ask about the same treatment under an auto or work injury claim, where the rules differ. Checking the plan before the package is sold keeps that conversation calm.
S8948, quick answers
Why do plans call cold laser investigational?
Their medical policies say the published studies are not strong enough to show a clear benefit. That wording makes it an exclusion rather than a medical necessity question.
Does Medicare cover cold laser therapy?
No. S8948 is not a valid Medicare code, and low level laser is not a Medicare benefit. A chiropractor cannot bill Medicare for it at all, so the patient pays cash and most offices get a notice signed anyway.
Does any plan pay for it?
A few commercial plans keep the code on a fee schedule, and auto or work injury claims sometimes pay. It is always worth checking and never safe to assume.
Can I use an HSA or FSA?
Usually yes, since it is a medical expense even without plan coverage. Keep the itemized receipt with the code on it and confirm with the account administrator.
What should the office quote me?
A written price per session or per package, and a clear statement that insurance is not expected to pay. Anything vaguer turns into a billing dispute later.
