The Reality of Single Case Agreements in 2026: What's Working and What's Not
Single case agreements (SCAs) have become increasingly difficult to secure across major payers, with Georgia providers reporting particular challenges with regional MCOs. While SCAs remain a viable pathway for select high-value cases, the administrative burden and declining approval rates are forcing most operators to prioritize network participation over case-by-case negotiations.

The Situation
Single case agreements — the mechanism allowing out-of-network providers to deliver services at negotiated in-network rates for specific clients — are facing heightened scrutiny from managed care organizations nationwide. In Georgia, two major Medicaid managed care plans dominate the conversation: one regional MCO which covers approximately 25% of the state's Medicaid population, and another regional MCO which has been gaining market share as other plans exit the state.
Both payers have tightened SCA approval criteria significantly over the past 12 months, with approval rates dropping from historical norms of 60-70% to current levels closer to 30-40%. The shift coincides with broader industry consolidation, as one regional MCO recently announced 20% rate cuts for in-network ABA providers, signaling increased cost containment pressure across all payment mechanisms.
Why It Matters
The Near-Term Impact
Providers are spending 40-60% more administrative time per SCA application with lower success rates, creating negative ROI on pursuit efforts for all but the highest-value cases. This forces immediate decisions about which families to serve and whether to invest in lengthy credentialing processes with plans that may not offer sustainable long-term rates.
The Broader Context
The SCA squeeze reflects payers' broader strategy to control network composition and utilization patterns rather than simply negotiate individual cases. As state Medicaid programs face budget pressure and managed care organizations consolidate, the path of least resistance is eliminating exceptions rather than managing them case-by-case — a trend we're seeing replicated in Texas, Florida, and North Carolina markets.
What We're Seeing in the Field
Multiple operators are reporting similar patterns across the Southeast region. One Georgia provider noted:
"We used to get SCAs approved pretty routinely with both regional MCOs. Now we're seeing denials on cases that would have been automatic approvals 18 months ago — even when there's clear network inadequacy in the area."
The documentation requirements have also intensified significantly. As another operator explained:
"They're asking for treatment plans, outcome data, and network adequacy justifications that go way beyond what we used to submit. It's like they're looking for reasons to deny rather than approve."
Several providers are questioning whether the administrative investment makes financial sense. A multi-state operator observed that they're tracking about 8-10 hours of admin time per SCA application — between the initial submission, follow-ups, and appeals. At typical billing rates, that requires at least 15-20 hours of approved service delivery just to break even on the admin cost.
Our Point of View
The SCA market is bifurcating into high-value exceptions and administrative waste. Payers are using procedural complexity as a de facto rationing mechanism, knowing that most providers will abandon pursuit rather than invest in lengthy appeals processes.
This isn't necessarily bad policy — it forces providers to make strategic choices about network participation rather than operating permanently on the margins. Smart operators should treat SCAs as a last resort for truly exceptional cases rather than a substitute for network development.
What Smart Operators Are Doing
Establishing clear SCA pursuit criteria
Only pursuing cases with minimum 6-month duration and 15+ weekly hours, with documented network inadequacy in the specific geographic area.
Outsourcing SCA administration
Contracting with specialized third-party authorization services to handle documentation and follow-up, converting fixed admin costs to variable per-approval fees.
Front-loading network participation
Prioritizing credentialing with dominant regional plans rather than relying on case-by-case negotiations, even when initial rates appear suboptimal.
Building referral source partnerships
Working directly with pediatrician offices and diagnostic providers to identify high-probability SCA cases before investing in applications.
Creating template documentation packages
Standardizing clinical justifications, network adequacy letters, and outcome measurement protocols to reduce per-case preparation time.
What to Watch
Rate announcements in Georgia, Texas, and Florida will signal whether payers view SCAs as temporary bridges or permanent exceptions.
Watch for expansion beyond Georgia's current 25% Medicaid share, particularly if Peach State or other plans exit additional regions.
