Getting Prior Authorization Right in Your Practice
By Brianna Hall, Director of Development, Medical Billing Center
The front desk in a PT clinic carries more responsibility than most people give it credit for. In a single day, that team is managing the schedule, verifying insurance, collecting payments, handling intake paperwork, tracking plans of care, and somewhere in the middle of all of that, securing prior authorization before a patient arrives for treatment. Each of those tasks matters, but prior authorization is the one that tends to create the most expensive problems when it gets missed, because by the time anyone realizes the authorization was not in place, the care has already been delivered.
The average PT practice spends roughly thirteen hours per week managing prior authorization requirements, and according to the 2025 AMA Prior Authorization Physician Survey, 83 percent of providers say authorization delays have caused patients to abandon treatment altogether. That is not just a billing problem, it is a patient care problem that starts at the front desk.
The Cost of Getting It Wrong
When a service requires prior authorization and it is not secured before treatment begins, the claim is typically denied, and the practice is left choosing between writing off the cost entirely or, where the contract allows, billing the patient for care they assumed was covered by their insurance. Neither outcome is good for the practice or the patient relationship, and both are almost entirely avoidable with the right process in place.
The financial stakes are real and industry data puts the average PT claim denial rate at approximately eleven percent in 2026, and missing or expired prior authorizations are consistently among the top contributing causes. Every authorization-related denial represents a clinical session that was already delivered, a billing team that now has to spend time investigating and attempting to appeal, and in many cases a write-off that could have been prevented at the scheduling stage. The earlier in the process these gaps get caught, the lower the cost of addressing them.
Where Requests Most Often Break Down
Most prior authorization request denials can be traced back to a small number of recurring problems, and what makes this worth understanding is that the majority of them happen before the request is ever submitted, which means they are preventable.
Eligibility issues are among the most common, where a patient’s coverage was not active or was not confirmed close enough to the date of service before the request went in. Incomplete or mismatched documentation is another frequent cause, where information is missing from the submission or the diagnosis code on the referral does not match what was included in the request. Coding errors, including the wrong CPT or ICD-10 code or a simple clerical mistake, get flagged before the payer ever evaluates the clinical merit of the request. Insufficient medical necessity documentation, where there is not enough clinical detail to justify the service, is one of the harder ones to catch internally because it requires understanding what each payer’s standard actually looks like for that service. And requests that come in after the approved visit count has already been reached are an authorization management problem, not a submission problem, which means the fix lives further upstream in how your team tracks remaining visits.
The pattern across all of these is consistent. Most prior authorization request failures are operational, not clinical, and they are addressable with the right systems in place before the patient ever arrives.
What Is Changing in 2027
There is a meaningful shift coming to how prior authorization works for a significant portion of payers, and PT clinic owners with Medicare Advantage, Medicaid, CHIP, or federally facilitated exchange patients should be aware of it now rather than in January.
Under CMS Final Rule CMS-0057-F, Medicare Advantage organizations, Medicaid managed care plans, CHIP managed care entities, and qualified health plan issuers on the federal exchange are required to have electronic prior authorization systems live by January 1, 2027. These systems, built on standardized FHIR-based technology, will allow practices to submit prior authorization requests and check their status electronically rather than relying on phone calls, faxes, and separate payer portals. The rule also requires these payers to decide standard requests within seven calendar days and expedited requests within 72 hours, and to provide a specific reason for every denial.
A few important things to understand about what this rule does and does not do. Practices are not required to use the electronic systems, and most commercial payers that are not on the impacted payer list are not covered by the rule. The change is on the payer side, not the provider side. But as more payers build out these capabilities, the process of submitting and tracking authorizations should become faster and more transparent over time, which has the potential to reduce the administrative burden that currently falls heavily on front desk teams.
What does not change is the fundamental responsibility to get authorization before providing care. The technology will evolve, but the requirement stays, and the practices that have strong workflows in place now will have an easier time adapting to whatever the landscape looks like next year and beyond.
MBC Helps You Stay Ahead of It
At MBC, prior authorization tracking is not an afterthought. It is a core part of how we support every clinic we work with, because we understand that authorization-related denials are some of the most preventable revenue losses in physical therapy billing. We keep track of what each payer requires, monitor remaining visit counts, and flag re-authorization needs before they become a problem rather than after a denial arrives.
We are led by physical therapists who understand this industry from the inside, and we are here to help your practice build the processes that protect your revenue before care is ever delivered.
