What Are The Actual Costs of Prior Authorization
%20(1).jpg)
Quick Learnings
Everyone who works in clinics knows that prior authorizations are hard, time-consuming, and frustrating. Yet, most haven’t actually added it all up.
You need to take staff time, denial rework, and interrupted care into the equation. As a result, prior authorization is likely costing your practice more per month than any other single administrative workflow, with almost none of it visible as a line item.
The monthly cost: where it comes from
Prior authorization costs show up in three places that most clinics don't track separately.
Staff time
A single prior authorization request, if submitted correctly, followed up on, and documented, takes anywhere from 20 to 45 minutes. This includes hold time, portal navigation, and EMR entry. Based on AMA data, practices complete an average of 39 prior authorization requests per physician per week, with staff spending around 13 hours on it weekly. Spread over multiple days and factoring in follow-ups and denials, internal calculations suggest this results in roughly 15–30 active requests at any time for clinics seeing 80–150 patients per week.
Assuming that the average front desk wage is $18–$22/hour, that adds up to $1,500–$3,000 in monthly labor just for authorization management, before accounting for follow-up calls, resubmissions, or appeals.
Denied and delayed claims
Authorization-related delays and claim denials remain one of the leading causes of revenue cycle disruption for specialty practices.
Each denied claim costs between $25 and $181 to rework, depending on practice size, so for a clinic submitting 200–400 claims per month, even a 5–8% authorization-related denial rate generates $2,500–$14,000 in monthly rework costs and delayed cash flow, based on straightforward calculations.
Interrupted care and lost revenue
This is the cost no one puts in a spreadsheet. When an authorization lapses mid-episode, your front desk scrambles, your therapist stops treatment, and your patient starts questioning whether to continue, and some don't return. That is uncollected revenue, which was already in your schedule.
What a "typical" month looks like
Based on the figures above (20–45 minutes per request at $18–$22/hour for staff time, plus denial rework costs of $25–$181 per claim at a 5–8% denial rate, and active authorization number estimates derived from AMA survey data and typical clinic workflows), the monthly costs break down as follows:
- Single-site or small group practice (1–3 locations):
These clinics typically handle 40–80 active authorization requests per month, translating to roughly 13–60 staff hours. Combined with denial rework, this results in $500–$7,000 per month in administrative costs, depending on staff efficiency and claim complexity. - Regional group (5–15 locations):
With 200–400 active authorization requests, total monthly costs scale to roughly $20,000–$50,000, including both staff time and rework. - Large group (25+ locations):
For clinics with 25 or more locations, active requests can reach 800–1,500+, leading to estimated monthly costs of $80,000–$180,000+. Most of this burden is invisible in standard profit-and-loss statements.
Why manual tracking breaks down at scale
Most clinics manage prior authorization through a mix of staff memory, spreadsheets, and portal logins that vary by location and staff member. For a single site, this works until someone leaves, gets sick, or has a particularly heavy week.
The real problem is structural: authorization management is inherently dynamic, payors update rules, visit limits reset, and approval windows expire on schedules that don't align with anyone's workload. So, a process that depends on staff staying on top of all of that will eventually miss something.
For multi-site groups, the problem compounds. Each location tends to develop its own documentation habits and its own threshold for "we'll deal with it when it gets denied," which makes it nearly impossible to identify where the breakdowns are happening or standardize quality across sites. Practices with standardized, auditable authorization processes consistently outperform ad hoc workflows on both denial rate and time-to-reimbursement. This gap only widens as a group scales according to HFMA's research on denials management.
How does automation solve the problem?
Lucy, a Voice AI agent by Health Ops by Spike, handles the full prior authorization workflow. It checks the authorization requirements by payor and service type, contacts carriers directly, and documents results into your EMR, without your staff initiating anything. When an appointment is scheduled, the process starts automatically, meaning your team isn't chasing authorization status or manually cross-referencing portals; instead, they can stay focused on in-clinic patient experience and edge cases that require special care.
When Lucy encounters a discrepancy that requires review, a specialist on our end steps in to reconcile the data before anything reaches your EMR. That human-in-the-loop layer is what produces a full audit trail and consistent documentation across every location, rather than a system that occasionally surfaces surprises at the worst possible time.
Does automation work for complex payors?
Health Ops by Spike works with 1,000+ payors across 45+ states, including the high-complexity plans that create the most friction in PT, OT, and SLP billing.
Through Spike RCM Intelligence, the system learns payor-specific behavior, memorizing which payors require multiple contacts, which update their authorization rules seasonally, and what documentation each plan needs, so that institutional knowledge accumulates in the platform rather than walking out the door when a staff member leaves.
The bigger picture
The clinics feeling the most pressure right now aren't necessarily the ones with the highest authorization volume; instead, they're the ones still treating it as a person-dependent process in an environment that's increasingly unforgiving of inconsistency and human error.
If prior authorization is consuming hours your team doesn't have, it's worth seeing how automation handles it in practice. Lucy manages the full verification and authorization discovery workflow, from the first carrier contact to the final EMR entry, so your staff can focus on patient experience, instead of being on hold with payors.

FAQs
Insurance verification confirms that a patient is covered and identifies their benefits, such as deductibles, copays, and visit limits. Prior authorization is a separate step where the payor grants approval for specific services before treatment begins. Many PT, OT, and SLP services require both, and each has its own payor-specific rules and timelines.
The time savings and denial reduction apply regardless of clinic size. Single-site and small-group practices often achieve the highest per-location ROI because they absorb the full labor cost with limited headcount.
With manual tracking, a lapsed auth is typically discovered when a claim gets denied, often weeks after the service was delivered. Automated systems flag auth windows before they expire and initiate reverification proactively, so your team knows about coverage issues before they interrupt care or create a billing problem.
Processing times vary by payor, but most authorizations take between two and seven business days when submitted correctly. Delays happen when documentation is incomplete, the wrong CPT codes are used, or the submission goes to the wrong portal.
Yes. Lucy by Health Ops by Spike checks the authorization requirements by payor and service type, contacts carriers directly, and documents results into your EMR automatically when an appointment is scheduled. For complex or ambiguous cases, a human specialist steps in to resolve the issue before it reaches your workflow. The result is faster turnaround, fewer missed auths, and a full audit trail, without adding to your front desk's workload.
