Every state runs workers’ comp its own way.
Yours has a name for everything.
W-codes and nine MCOs in Ohio. MARFS Chapter 25 units for L&I in Washington. QRC hourly invoices and R-forms through Campus in Minnesota. Board Rule 200.2 time bills in Georgia. Pick your state and read what we found — who you bill, on what form, through what channel, on what fee basis, under what clock.
Fifty-one front doors.
Workers’ compensation is the most state-fragmented corner of American insurance: four monopolistic state funds, roughly eighteen competitive state funds, private carriers and TPAs everywhere, and a different vocational-rehabilitation statute in every legislature. That is not an inconvenience to be smoothed over — it is the reason generic billing software has never fitted this job. Nobody builds a product for a market that is fifty different markets with a few thousand people spread across them. So the job got done in Excel, and it has been getting done in Excel for twenty years.
Six states where the whole chain is set up.
Registered or certified private vocational-rehabilitation markets that work the way Ohio’s does: a defined professional role, a payer set we can name, and a fee basis or invoice convention we have verified. Ohio is the flagship — the software was built inside a working Ohio voc-rehab practice.
Nineteen states with real vocational work and their own procedures.
A statutory benefit, a certification, or an active insurer-retained market — smaller than the six above, or procedurally particular. Your codes, forms, payers and templates are configured in your first week, included in every plan. We have not claimed a customer in any of them, and you will not find one claimed on their pages.
Twenty-six jurisdictions where the vocational benefit was repealed, is state-delivered, or was never funded.
California repealed it in 2004; Colorado in 1987. Idaho’s Industrial Commission does it itself, free. Connecticut and Rhode Island run their own programs. Mississippi’s statutory allowance is $25 a week. These pages say so plainly, and then sell the thing that is real everywhere: invoice-based nurse case management billing, which needs no state setup and works in all fifty states today.
Where the money comes from, and how the bill has to travel.
The four monopolistic funds
In four jurisdictions employers must insure through the state, so there is one payer and one set of rules:
- Ohio BWC (billed through its nine MCOs)
- Washington L&I
- North Dakota WSI (myWSI)
- Wyoming Workers' Compensation
Ohio is the odd one out: it routes every bill through one of nine employer-selected MCOs rather than to the fund itself.
Electronic billing, honestly
Providers must bill electronically in TX, MN, NC, TN, VA, NY, CO. Payers must accept electronic bills in CA, IL, LA, OR. Everywhere else fax, paper and portals remain first-class.
We do not submit electronically. Med Claims Pro builds the bill, the documentation and the receivable and files proof of what you sent; direct e-billing is on our roadmap and no page on this site describes it as shipped.
Current as of July 2026 — verify with your state agency.
What we will say about your state, and what we will not.
Facts, sourced and dated
Every statute, rate, form and payer on a state page is transcribed from the agency or the statute named, and every rate table carries the month it was verified. Where a fact is not confirmed, the page says so instead of filling the gap.
No customers we do not have
There is exactly one customer practice behind this software, in Ohio, and it is anonymized. You will not find “trusted by” anywhere on a state page, because it would not be true. This profession talks to itself and one burned buyer costs more than a lost one.
Configured, not generic
Your templates, folder tree, file naming, payers, rates and forms are set up during onboarding in your first week — included in every plan. That is how the software fits a state we have not shipped a pack for, and it is also how it fits Ohio.
The codes change. The week does not.
Vocational rehab professionals
VRC, VRCM, QRC, rehabilitation supplier, rehabilitation practitioner, vocational counselor, vocational expert. Different letterhead, same week: coded, timed activities that become a daily log, a weekly narrative, a claim form or invoice, and a receivable.
Nurse case managers
Field or telephonic, in every state, billing carriers and TPAs by the hour with mileage and wait time. Invoice-based case-management billing is state-agnostic, which is why it works everywhere today — including the twenty-six jurisdictions above.
Not sure which page to read first? Call and say your state: (302) 202-3172. Somebody answers, and if the honest answer is that your state is thin, you will get that instead of a demo.
Questions, answered.
Why does workers’ comp need fifty-one different pages?
Because it is fifty-one different systems. The professional’s statutory title, the payer, the form, the submission channel, the fee basis and the filing clock all change at the state line. A QRC in Minnesota invoices a carrier by the hour and files R-forms through Work Comp Campus; a VRCM in Ohio faxes a CMS-1500 in W-codes to one of nine MCOs. Software that speaks one of those does not speak the other.
Can I use Med Claims Pro in a state you have not built yet?
Yes. The workflow — type each activity once, and the daily log, the narrative logs, the claim form or invoice and the receivable build themselves — is the same everywhere. Your state’s codes, forms, payers and rates are configured during onboarding in your first week, included in every plan. Invoice-based nurse case management billing needs no state setup at all.
What do the three tiers actually mean?
Tier 1 means the whole chain for that state is set up and we will show it to you on a demo. Tier 2 means there is real vocational work in that state and we configure your codes, forms and payers during onboarding — we are not claiming customers or portal integrations there. Tier 3 means the vocational benefit is repealed, state-delivered or never funded, so the page tells you that and sells the nurse case management workflow, which is genuinely available today.
Do you do electronic billing in the mandate states?
Not today. Providers must bill electronically in Texas, Minnesota, North Carolina, Tennessee, Virginia, New York and Colorado, and we do not submit for you in any of them. Med Claims Pro builds the bill, the packet and the receivable and files proof of what was sent. Direct e-billing is on our roadmap, and if that is your deciding feature, ask us on the call where it actually is.
How current are these rates and rules?
Everything was verified in July 2026 against the state agencies’ own publications, and every rate table on the site carries that date and the agency to verify it with. Fee schedules move — Ohio republishes in October, Washington in July, Minnesota indexes annually — and rate changes ship to customers as data updates, with historical entries keeping the rates they were billed under.
I work claims in more than one state.
Then the jurisdiction has to belong to the claim rather than to your memory, which is how it works: pick the claimant and their state’s forms, payers and rates come with them. Professional includes one state setup and adds more at $49 a month; Practice includes them all. Pricing.
My state page has a fact wrong. Will you fix it?
Yes, and quickly — call (302) 202-3172 or email admin@onservice.us. These pages are a reference we maintain, not marketing collateral we forget about, and a wrong rule number does us more damage than it does you.
See your own week run itself.
We load your state’s codes before the call, so you are looking at a caseload like yours inside the first two minutes — not a slide deck.
