Most ABA practices accept whatever rate a payer offers. They’re new. They need access. They don’t want to rock the boat.

That instinct costs money for years.

Payer contracts lock in your rates. Renegotiating is slow and usually only possible at specific windows. The rate you sign today is the rate you bill at for the next two to three years — sometimes longer.

Here’s how to approach contract negotiation whether you’re signing your first contract or entering a renegotiation cycle.

When You Can Negotiate

Not all contracts are negotiable on your timeline.

Commercial payers — Cigna, Aetna, UnitedHealthcare, regional BCBS plans — typically open rate discussions when:

  • You are a new provider being credentialed for the first time
  • You have completed an initial contract period (often 24 months)
  • You bring a patient volume the payer wants (50+ covered members, for example)
  • You are in a geography with limited or no in-network ABA access

Medicaid managed care organizations (MCOs) operate differently. Rates are often set at the state level through published fee schedules. Negotiation room is limited, though it varies by state and by plan. Some MCOs do negotiate rates with larger or higher-volume providers.

Start your effort where you have the most leverage: commercial carriers credentialing you for the first time. You have one shot to set baseline expectations. Don’t walk in without a proposal.

Build a Rate Proposal Before You Talk to Anyone

Letting the payer define the floor is the most common negotiating mistake small practices make.

A credible rate proposal includes four things:

1. Your cost basis. What does it actually cost to deliver one unit of 97153? Include direct labor (RBT wages plus supervision hours), overhead allocation, and billing costs. If you do not know your cost per unit, calculate it before doing anything else. You cannot negotiate a sustainable rate without this number.

2. A benchmark rate. Medicare does not cover ABA services directly, but the Medicare Physician Fee Schedule is a standard reference point that payers use for analogous behavioral health codes. Understanding where your requested rates land relative to Medicare gives payer reps a frame they recognize.

For ABA-specific rate data, mymetolius.com publishes a fee schedule tool with payer-level rate data by CPT code and geography. It is one of the few places you can see what commercial payers are actually paying — not just the offer letter in front of you. Use it to build your benchmarking case before you get on the phone.

3. Regional UCR data. “Usual, Customary, and Reasonable” rates are what payers define as typical charges for a service in a market. You can access UCR data through FAIR Health’s public tools or your state insurance commissioner’s published data. Use it to demonstrate that your requested rates are within market norms — not outliers.

4. Your quality case. Outcomes data, low cancellation rates, fast intake-to-treatment timelines, proximity to underserved zip codes — anything that makes you a more reliable network option than the next group. Payers want providers who show up consistently, stay credentialed, and don’t generate complaints.

The CPT Codes That Matter Most

Not every code carries equal weight. Focus your negotiation on:

  • 97153 (Adaptive behavior treatment by protocol, technician) — your highest-volume code by far
  • 97155 (Adaptive behavior treatment with protocol modification, BCBA) — your highest-margin code
  • 97156 / 97157 (Family adaptive behavior treatment guidance) — increasingly covered, frequently underpaid

A 5% rate increase on 97153 compounds fast across a caseload of 20 clients billing 25 hours per week. Run the math before you negotiate. Know what each percentage point is worth annually for each code. Walk in with those numbers.

Single-Case Agreements: The Underused Lever

If a payer will not credential you outright, ask about single-case agreements (SCAs).

An SCA lets you treat an individual covered member as an out-of-network provider at negotiated rates — without full panel credentialing. SCAs are typically available when:

  • A member has an existing treatment relationship with you and the family does not want to switch providers
  • The payer has no in-network ABA provider within a reasonable distance from the member’s home
  • The member or family is actively pushing the plan for access

SCAs are leverage. Once you are treating four or five members through SCAs with a carrier, you are in a much stronger position to request network inclusion — and to anchor the rate conversation based on what you have already been paid through the SCAs.

Track every SCA. Document the payer, the rate, the member zip code, and the dates of service. This is your evidence base when you push for full credentialing.

Get Your Billing Data Clean Before the Conversation

Payers track utilization patterns. A high denial rate or a clean claim rate below 90% signals billing problems — and billing problems translate to administrative burden for the payer.

Before entering any rate negotiation, make sure your claims data is not working against you. A payer rep who pulls up your history and sees a 22% denial rate is not going to offer a premium rate. Track the RCM metrics that payers care about before you sit down to negotiate.

Clean claims go in. Payments come out. Credible data supports a credible rate ask.

The Short Version

  1. Build a rate proposal with your cost basis, benchmark data, and UCR support — use mymetolius.com to see what payers in your market are actually paying
  2. Know your key CPT codes and what each 1% improvement on 97153 is worth annually
  3. Use single-case agreements to build a track record with carriers that won’t credential you yet
  4. Do not sign a contract rate you cannot sustain for two years

Payer contracts are not paperwork. They are the financial foundation of your practice. Treat them that way.
