Ask any biller who’s worked both commercial and workers compensation claims, and they’ll tell you the same thing: the CPT codes might look identical, but everything else is different.
A visit that is paid with a commercial plan can remain undervalued for two months under workers’ comp, not because of a mistake, but because of some different assumptions in the system.
Most practices are losing money on that mismatch. They follow the same corporate billing process as they would when making a claim make a claim, waiting for the EOB, and appealing if the claim is denied, but they are doing it to a process that was never designed that way. Workers’ comp is not a slow type commercial. It’s just another process, and treating it as such is a sure way to kill collections.
The Payer Isn’t Just an Insurer — It’s an Investigator
The “payer” in commercial insurance is responsible for confirming the insurance and handling the claim. The carrier’s adjuster is also considering whether the injury is valid, work-related, and whether the treatment matches the authorized treatment. That’s another layer of review that commercial claims do not have.
This means a claim can be medically sound and still get held up because:
- The adjuster is requesting clarification on the cause of the injury (did the job cause the injury)
- Treatment not yet approved by Utilization Review (UR)
- A dispute notice and/or delay notice has been filed by the employer.
- The diagnosis that the treatment is being administered does not match the accepted body parts on file.
This is not reflected as a denial code. It appears as a quiet, and silence is more difficult to sell. If the claim is denied, you have something to work with: a reason code, an appeal path. An unanswered workers’ comp claim not only means you’re missing, but also you don’t have anything to act on until someone in your organization recognizes it and makes the calls.
Authorization Comes Before Treatment, Not After
In commercial billing, prior authorization is often a formality associated with a few high-cost procedures. Authorization is the key in workers’ comp. If treated before UR approval, the treatment is one that the carrier will NOT have to pay for, even if determined to be medically necessary.
This reverses the typical billing order. As opposed to treating first, bill second, workers’ comp works according to the rule of confirm first, treat second, document third, and that’s one of the most frequently overlooked steps that leads to claims languishing in appeal limbo.
It’s also one of the most difficult habits that will be hard for clinical staff to shed. A doctor who knows how to treat a patient based on his needs and what he needs, not what a carrier approves, will often provide care even before authorization is received, especially if the treatment involves pain management or physical therapy, where it feels as though it is “the wrong thing to do” to wait for authorization. The issue is that this is a good instinct, but it leaves a billable deficit that can’t be filled after the fact with clean documentation.
Fee Schedules Are Set by the State, Not the Payer
Commercial insurance is on a contracted rate basis, where the practice and the payer negotiate the rate. State determines the fee schedules for workers’ compensation, and they are different depending on specialty, jurisdiction, and, in some cases, year. It is the equivalent of three different practice rules and three different reimbursement policies for the same CPT code.
Miss an update to one state’s schedule, and the claim is automatically underpaid or will be flagged for manual review, adding weeks to a normal payment. Some states also have different schedules for surgical care and non-surgical care, or even for the rates for surgical care to change each year according to a formula related to Medicare’s conversion factor.
If the billing team is not diligently monitoring these changes on a state-by-state basis, then they can be sure to submit a claim with an incorrect rate, and this is exactly what leads to the manual review that slows down everything.
Documentation Has to Prove a Different Thing
Medical necessity is supported by commercial billing documentation: Was this treatment warranted for this diagnosis? Workers’ comp documentation must take a step further and establish causation – that is, does this treatment directly relate to the accepted work-related injury?
If this is a note that states “patient reports ongoing shoulder pain” and this doesn’t connect back to the original incident and to the body part designated on the claim, it means nothing to an adjuster. If that connection is not there, the adjuster has a reason to slow down the payments, but not to refuse to pay.
Why Practices Keep Getting Caught Off Guard
The pattern continues: a practice that has a streamlined commercial billing process expects workers’ comp to work similarly, albeit at a slower pace. It doesn’t. It’s based on authorization sequencing, causation-specific documentation, and state-by-state fee logic that commercial claims never interact with.
This is the core issue behind stalled workers compensation billing. It isn’t a slower version of commercial insurance; it’s a structurally different process, and practices that don’t separate the two end up chasing claims that were never going to move under a commercial-style workflow.
What Practices Can Do Differently?
- Ensure that authorization for treatment is confirmed for UR prior to treatment, not after treatment; record the date of authorization.
- Use the term causation in every note and name the accepted body part and link it to the treatment offered.
- Monitor each state’s fee schedule independently, and check for changes every 4 months, not 1 year;
- Make a note before 30 days if there is no movement from the adjuster.
- Make sure one person is responsible for each claim for adjuster communications to be consistent
The Bottom Line
Workers’ comp isn’t commercial insurance with extra paperwork; it’s a separate system with its own logic for authorization, documentation, and payment. Practices that keep applying commercial workflows to workers’ comp claims will keep watching them stall for reasons that never show up on a denial report. The ones that treat it as its own process, with its own rules, are the ones who actually get paid on time. Learn more: www.doctormgt.com
