OKLAHOMA BILLING FACTS · NURSE CASE MANAGERS SUPPORTED TODAY

Oklahoma workers’ comp case management billing —
§45(E), and what happens the rest of the time.

§45(E) lets a judge order vocational rehabilitation on an Oklahoma claim, which makes it episodic rather than a practice. CompSource Mutual and the private carriers pay nurse case managers steadily, and that is the work with a rhythm you can plan around.

One check, four claimants, one short-pay caught at $16.14, $674.07 still owed. Invented names, real workflow — and the same screen whether you invoice a TPA in Oklahoma or an MCO in Ohio.

Every one of those rows is typed once, as it happens. The daily log writes itself as you go, the weekly narrative log builds in your own Word template, the invoice fills with the right units and the right payer block, and the receivable exists the moment the bill leaves. The whole chain →

Ordered work is episodic work

You cannot staff a practice around a judge’s discretion.

Under §45(E) vocational rehabilitation happens when a judge orders it. Those referrals are real and they are also unpredictable, which is a difficult foundation for a practice.

CompSource Mutual and the carriers pay for case management continuously. That is the work we can help with in Oklahoma today, and it needs no state pack.

The payer directory

Who pays you in Oklahoma.

CompSource Mutual is the largest local name, with the national carriers and TPAs behind it. Vocational referrals come from the bench; case-management referrals come from adjusters.

  • CompSource Mutual
  • Private carriers

  • Travelers

  • AmTrust
  • Zurich
  • Chubb

One check, many claimants. Whichever of these names is on the envelope, the check covers a dozen files at once. You record it once, tick the bills it pays, and anything short is flagged with the exact gap and the original form attached, ready to rebill. How that screen works.

Payer fax numbers and billing addresses go stale faster than any page can keep up, so we publish them only where we keep them current — today that is Ohio’s nine MCOs. Your Oklahoma payers, their submission addresses and their quirks get set up during onboarding, from your own files.

What is genuinely for sale here today

Case files, adjusters, mileage, invoices.

Nurse case management billing works in Oklahoma today: activity grid, itemised invoice, mileage and wait time on their own lines, and aging by payer.

The activity grid

Field visit, telephonic call, wait time at the appointment, the miles there and back — logged once, with the claim number, the adjuster and the referral source attached as you type.

The itemised invoice

In the format the payer asks for, from the same entries, with the activity log behind it. No CMS-1500 unless your payer wants one — and some do.

Aging by payer

CompSource Mutual, the carriers and the TPAs, each with billed, paid and still-owed, and an aging list that names who is sitting on your money.

It is the same week Dana works in Ohio with different nouns: case files instead of claimants, adjusters instead of MCO coordinators, billable hours and mileage instead of W-codes. The nurse case manager page has the whole workflow.
