All Things Medical Billing Academy
Practical, practitioner-to-practitioner how-to lessons for doing your own billing well — clean claims, eligibility workflows, denial & appeal playbooks, A/R workups, and credentialing steps, taught in plain English by a working biller who does this every day.
Built for people who already have their billing education — this is the practical side school doesn't teach.
No fluff, no theory-only lectures. Real workflows, real documents, real fixes — for health insurance, workers' comp, and personal injury.
Inside the Academy
- Clean-claim workflows
- Eligibility & benefits checks
- Denial & appeal playbooks
- A/R follow-up systems
- Prior authorization tracking
- Credentialing, step by step
Who this is for
You have the education. This gives you the day-to-day.
School taught you the terms and the rules. The Academy shows you what to actually click, call, document, and send — in the order a real billing office does it.
Office managers & practice staff
Run the front end so claims don't break on the back end: verify before the visit, track authorizations, calculate patient responsibility, and keep COB issues from becoming denials.
Practice owners running their own billing
Keep billing in-house with confidence — a full revenue-cycle view, A/R workups that actually move money, and credentialing steps for your own providers.
