What we do
Every step of the revenue cycle.
We run every stage of the revenue cycle ourselves, so a problem gets caught where it starts instead of bouncing between vendors.
- 01
Benefits, Eligibility & Patient Intake
Verify coverage and set patients up correctly before the first claim is ever built.
- 02
Authorization & Utilization Review
Auth and UR workflows managed end-to-end — preparation, scheduling, documentation, deadlines and peer-to-peer coordination.
- 03
Claim Build, Submission & Follow-Up
Claims reviewed through defined clean-claim controls before submission, with active follow-up worked through to resolution.
- 04
Payment Posting & Reconciliation
Payments posted and reconciled line-by-line against contracted rates to catch what's short.
- 05
Denials, Appeals & Aged AR
Root-cause denial resolution, appeals and recovery of stalled aged-AR — worked in priority order.
- 06
Reporting, Underpayments & Payer Intelligence
Structured reporting plus underpayment detection and the payer intelligence behind every decision.
Behind every claim
A person in treatment is counting on it.
The numbers we chase are sessions, beds and programs that stay open. We run the billing so the people doing the clinical work never have to choose between care and cash flow.
When billing works, treatment continues.
Our approach
How we actually get you paid.
Axis IRG combines behavioral-health billing expertise with payer intelligence to solve the root causes of claim denials and revenue leakage before they compound.
/01
We only do behavioral health
Detox, RTC, PHP and IOP billing is all we work, not one service line among many.
/02
We find why it denied
Before another claim goes back out, we figure out what actually caused the denial.
/03
We catch it early
Problems get spotted upstream, before they cost you a month of cash flow.
/04
You get a real team
A named team that knows your census and answers when you call.
