The Quiet Exit From Private Insurance Contracts
Across the country, regional radiology billing groups are making a calculated decision: walking away from private pay contracts with major insurers. The exits are not loud or dramatic. There are no press releases, no earnings calls, no public statements. Groups simply notify insurers that they will not renew, and then they stop being in-network. Patients often find out only when the explanation of benefits arrives showing a balance due that their deductible and copay were never designed to cover.
This is not a fringe movement. The pattern is showing up in multiple regions simultaneously, from mid-sized metro markets to rural hospital systems that contract with independent radiology groups for reads and billing. The reasons behind the exits are layered, and the consequences for patients, hospitals, and the broader insurance market are only beginning to surface.
Why Radiology Groups Are Walking Away
The core problem is reimbursement math that no longer works. Private insurers typically reimburse radiology services at rates tied to a percentage of the Medicare fee schedule. Over the past several years, those rates have been renegotiated downward in many regional markets, while the operational costs of running a billing group – staffing, compliance, software, appeals processing – have moved in the opposite direction. When the spread between what it costs to process a claim and what the insurer actually pays becomes narrow enough, staying in-network stops making financial sense.
There is also the administrative burden to consider. Radiology billing is among the most complex in medicine. Each modality – MRI, CT, PET, fluoroscopy, interventional procedures – carries its own coding structure, prior authorization requirements, and documentation standards. Private insurers have added layers of pre-authorization requirements over time, and denials on first submission have increased for many groups. The cost of re-submitting, appealing, and following up on denied claims is real and labor-intensive, and insurers are not reimbursing for that overhead.
Some groups have also hit the ceiling on what they can negotiate. Large national radiology billing platforms and private equity-backed groups have more leverage at the negotiating table because they represent higher claim volume. A regional group covering two or three hospital systems in a secondary market does not have the same pull, and insurers know it. The take-it-or-leave-it dynamic has pushed some groups toward the door.
The No Surprises Act, which took effect in 2022, was supposed to protect patients from unexpected out-of-network charges in emergency and certain facility-based settings. And in those situations, it does provide a framework. But it also created an independent dispute resolution process that many smaller billing groups describe as expensive, slow, and frequently unfavorable to providers when the insurer is a large plan with in-house legal and arbitration resources. For regional groups that go out-of-network in non-emergency contexts, the dispute resolution process is less relevant – but the patient billing exposure is real and creates a different kind of reputational risk.
What This Means for Hospitals and Health Systems
Hospitals have a stake in this beyond the obvious. When a radiology billing group exits a private pay contract, patients who receive imaging at that hospital are technically receiving out-of-network professional services even if the facility itself is in-network. That creates confusion, complaints, and sometimes legal exposure for the hospital, which is often seen by patients as the responsible party regardless of which entity actually bills for the radiologist’s professional component. Some hospitals are responding by bringing radiology billing in-house or by requiring any contracted radiology group to maintain in-network status with the major payers in their market as a condition of the contract.
That requirement creates its own tension. If a hospital insists on in-network status but cannot guarantee a higher reimbursement rate from the insurer, the radiology group is being asked to absorb the financial loss as a cost of keeping the hospital contract. Some groups are starting to factor this into their hospital contract negotiations, pushing for facility subsidies or stipends to offset the difference between what insurers pay and what the group needs to remain solvent. That dynamic is quietly reshaping how radiology services are contracted across the country.
The Patient Exposure Problem
For patients, the immediate consequence is financial unpredictability. Someone who schedules an MRI at an in-network hospital, verifies their coverage in advance, and follows all the right steps can still receive a separate bill from the radiology group that their insurer pays at out-of-network rates. The gap between what the insurer pays and what the group charges can be substantial, particularly for complex imaging reads or interventional procedures.
This kind of billing experience erodes trust, and patients have little mechanism to anticipate it in advance. Most insurance member portals do not flag which professional groups billing from a facility are in or out of network at the time of scheduling. By the time the patient knows there is a problem, the procedure is already done. Some states have passed balance billing protections that extend beyond the federal No Surprises Act, but enforcement is uneven and many patients do not know what protections apply to them or how to invoke them.
The groups exiting contracts are not necessarily acting in bad faith. In many cases, they have run the numbers and concluded that operating at the rates on offer is not sustainable, and that out-of-network billing – even with the friction it creates – generates better revenue. That logic holds especially when a group has subspecialty expertise in areas like neuroradiology or musculoskeletal imaging, where the clinical need is high enough that patients and referring physicians have limited alternatives.
A Structural Problem Without an Easy Fix
The exits will not stop until the underlying reimbursement problem is addressed, and there is no indication that insurers are preparing to move rates upward in regional markets. The economics that are pushing regional groups out of contracts are the same economics driving consolidation elsewhere in the healthcare industry – the same pressure that has led regional testing labs to sell to national networks rather than try to survive as independents in an environment where scale determines margin.
Some groups will eventually sell to larger platforms rather than continue negotiating from a position of weakness. Others will hold out and manage a mixed payer model, taking some contracts and leaving others, depending on rates. A few will exit the market entirely, particularly in rural areas where patient volume is too low to sustain the overhead even at fair reimbursement rates.
The groups that remain independent and out-of-network in high-demand markets may actually find that their leverage increases over time, particularly if the scarcity of in-network radiology reads becomes visible enough to pressure insurers. Whether insurers respond with better rates or with narrower network requirements that push patients toward hospital-employed radiology services is the question that will define the next phase of this standoff.
