Best Prior Authorization Companies for Medical Practices in 2026 (Compared) 

Key takeaways 

• Outsourced prior authorization support can cover requirement checks, documentation, submission, payer follow-up, and appeals. 

• Providers may charge per authorization, by staff capacity, or as part of a broader billing or revenue cycle contract. Published pricing is limited. 

• CMS decision-time rules and future API requirements apply to certain payers; they don’t guarantee approval. 

• Ask for written service levels, reporting examples, security terms, and a clear process for denials. 

When a service needs approval before care can proceed, a slow or incomplete request can disrupt scheduling and create avoidable billing problems.  

According to a 2025 American Medical Association study, doctors must handle about 40 authorization requests every week. This takes doctors and staff about 13 hours. This guide only compares prior authorization companies that help providers do their jobs. It does not compare companies that decide if a payer’s members are eligible for coverage. The AMA talks about the reported workload. 

If a practice wants to use prior authorization services, it should look at how each provider handles paperwork, follow-up, and authorization-status reporting, as well as payer-specific needs. 

Three Kinds of Prior Authorization Companies 

Prior authorization companies can refer to three different things: medical practices that hire outside teams to do work, health plans that hire utilization management companies to do work, or software that helps move requests online.  

Category	What it does	Examples
Outsourced service providers	Outsourced service providers assess practices’ needs, write and send requests, stay in touch, and keep records of decisions.	The providers compared below
Payer-side utilization management firms	Help health plans with utilization review and other related tasks.	EviCore, Carelon and Optum
ePA software and networks	Help companies send or handle requests online with ePA software and networks.	CoverMyMeds and Availity

An ePA tool may work well with an outside team, but it’s not always a replacement. Find out if the vendor will use the payer portals and EHR that you already have, connect to electronic workflows that are supported, or give you its own platform. 

What Prior Authorization Services Include? 

A prior authorization service typically handles the steps between the order and the payer’s decision. This includes checking benefits and authorization requirements, gathering clinical paperwork, submitting the request, and tracking it through to a response.  

A complete workflow may include: 

• Check eligibility and benefits. Confirm insurance eligibility verification to ensure they are covered under their plan. 

• Check whether authorization is required. Identify the service, place, plan, and CPT or HCPCS numbers that go with the payer’s rules. Medical coding services that are accurate can help the team identify the right set of codes to check. 

• Gather clinical support. Gather the notes, test results, treatment history, or referrals that the payer requests so you can determine whether the care is medically necessary. 

• Submit the request. Use the method the payer prefers, such as a portal, fax, or online process. 

• Track and follow up. Track submission dates, reference numbers, any remaining information needed, and payer responses. Send urgent requests to the practice. 

• Log the decision and its limits. Write down the authorization number, the dates of the approved service, and any visit or unit limits so that the billing team can match the approval to the claim. 

• Address denials and next steps. Support may include a peer-to-peer review, an appeal, or denial management services, depending on the agreement. 

Workflow: Order received; eligibility and benefit checks done; authorization requirements looked up; clinical paperwork gathered; request sent; follow-up with payer; decision recorded; claim checked against authorization. 

Best Prior Authorization Companies for Medical Practices 

On their websites, these service providers talk about prior authorization support. Different companies sell different things. Some offer a separate process for authorization, while others include the work in virtual hiring or a bigger RCM contract. Before you sign a proposal, make sure you understand the exact duties, specializations, staffing model, and reporting structure. 

Credex Healthcare

Best for: Practices looking to coordinate prior authorization with eligibility checks and broader revenue cycle work 

Credex Healthcare offers a prior authorization service for medical practices that covers the entire process. The written process includes identifying required authorizations, submitting requests, tracking decisions, and helping with challenges. The company’s website says it has a 99% first-time approval rate and that it takes an average of two hours from receipt to submission. These are vendor-reported numbers, so make sure you understand how each metric is defined and if it applies to your specialty and payer mix. Credex Healthcare’s prior authorization page details its stated services and metrics. 

MyOutDesk

MyOutDesk talks about medical billing virtual assistants who can ask for permission for procedures, imaging, and specialty referrals, keep track of the status, follow up with payers, and escalate cases that need to be dealt with quickly. The plan depends on staffing: determine whether the person you’ve been assigned will focus on prior authorization or split their time between billing and administrative tasks. 

P3 Healthcare Solutions

P3 Healthcare Solutions sells medical billing and other healthcare services, but the provider-side prior authorization service wasn’t made clear in the company’s papers that this piece looked at. We have not treated P3 as a proven authorization seller because the brief says that companies must be checked out on their own websites. Practices that want to use its billing services should find out if authorization work is available, who does it, and what needs to be written down. 

Revele (Formerly GroupOne Health Source)

A Revele (Formerly GroupOne Health Source) RCM presentation lists authorization as a front-end workflow activity, along with verifying eligibility, making referrals, and doing other billing tasks. This information is older, though, and it doesn’t prove that the hired service still covers what it claims it will. Before you decide if GroupOne is a good fit, ask for a current service description and an example of an authorization report. 

Integra Global Solutions 

Integra Global Solutions’ RCM service description lists insurance verification and pre-authorization, along with coding, claims, denial management, and accounts receivable follow-up. The provider shows authorization as part of a bigger process. Find out how requests are sent, tracked, and returned to your team.  

Hamly Business Solutions 

Hamly Business Solutions supports a program called “prior authorization,” which offers faster routes and keeps track of re-authorizations. Its website also describes additional RCM services. Because of the performance claims on the marketing page, get definitions, sample reports, and field-relevant references before you trust them.  

Transcure

Transcure talks about outsourced prior authorization that includes specialist help, tracking status, follow-up with payers, appeals, peer-to-peer coordination, and workflows that are aided by technology. The business also posts numbers about success and returns on its website. These are claims from the vendor. You should ask how they came up with them, what they cover, and if they apply to your service mix. Transcure’s prior authorization page explains how it works. 

BillingParadise

BillingParadise covers EHR integration, case tracking, payment follow-ups, appeal management, and checks to confirm authorization requirements are met. Its website also talks about customized support and a mix of technology and human review.  

MedKloud Billing 

The information we had for this comparison didn’t make it clear whether MedKloud Billing currently provides provider-side prior authorization. Ask the company to describe its current services, including whether it checks the needs of payers, sends requests, keeps track of choices, and follows up. Practices shouldn’t think of it as an authorization outsourcing choice until that scope is proven directly. Instead, they should look at it as a billing source. 

AMBSI Inc. 

As part of its medical billing and RCM business, AMBSI offers prior authorization as a service. It also says that tracking authorizations is part of this. Its website highlights its experience with pain management, anesthesia, ASC billing, and pricing for group practices. Ask if its team oversees sending in all requests and following up with payers, or if they mostly just keep track of authorizations for billing work.  

TaskUs

TaskUs offers a list of services as a provider. These include insurance verification, claims and billing, data entry, and records management. It also talks about services for payers, so practices should make it clear that the suggested scope is working on the provider’s side to authorize claims. On its healthcare page, the company is trying to reach groups that want more than just a small-practice authorization package.

How Much Does Prior Authorization Outsourcing Cost? 

Before authorizing someone to do something, the price will rely on what the seller does, how many requests your practice sends, how many staff members you need, and whether the service includes billing. 

To compare the price to work that you do in-house, look at the number of approvals, staff time, resubmissions, meetings that are late, and claims that haven’t been paid because approvals were missing or expired. The cost of a request can increase after the first submission if it needs follow-up or an appeal. Practices reviewing unpaid balances may also want to assess aging AR cleanup and the true cost of medical billing services. 

Prior Authorization Rules Changing in 2026 

In CMS-0057-F, decision deadlines and transparency requirements were put in place for some payers. Later, API requirements will follow. In general, the most time that can be spent on requests for Medicare Advantage, Medicaid, and CHIP programs that are affected is 72 hours for accelerated requests and seven calendar days for regular requests. These are the deadlines by which payers must make decisions. They do not promise that a practice will be approved or that a submission will be complete on the first day. CMS explains the timelines and affect programs. 

The API timetable is different. Starting January 1, 2027, some affected payers will have to use Prior Authorization APIs. The exact dates depend on the type of payer. CMS says the APIs are meant to support electronic workflows by handling tasks like determining what paperwork is needed and sending and receiving data. CMS summarizes the electronic prior authorization implementation. 

How To Choose A Prior Authorization Company 

If you hire the right company, they can handle the repetitive administrative work, but you still need to see which requests are open and hand them off clearly when clinical judgment is needed.  

Use these questions when talking to vendors: 

• What types of procedures, specialties, and payers do you support today? 

• Who checks to see if permission is needed, and how often do payer rules get looked at? 

• What portals, EHRs, and ePA do your employees use? 

• What do you need from our clinicians, and how do you handle missing records? 

• How do you report submission time, payer turnaround time, and cases that are still open? 

• Who monitors the end dates, visit limits, and units of authorization? 

• What happens after an authorization is denied? What are the options for appeals and peer reviews? 

• How much does it cost, what are the terms of the contract, and will you sign a HIPAA business associate agreement (BAA)? 

Prior Authorization by Specialty 

Authorization needs vary from service to service, payer to payer, plan to plan, and clinical record to clinical record. A vendor’s knowledge should match your practice’s work. Imaging, heart, cancer, orthopedics, pain management, mental health, and physical therapy may all have different needs when it comes to paperwork and follow-up.  

For specialty fit, review the company’s experience with cardiology billing, pain management billing, mental health billing, family practice billing, or prostheses, as relevant. Physical therapy practices can also compare physical therapy billing outsourcing and mental health billing companies. 

Prior authorization can be bought as a separate service, along with medical billing, or as part of full RCM. The best scope depends on where your workflow delays and turns down to start. It might be enough to have a focused team if permission is the main problem. If the issues keep happening with coding, submitting claims, making payments, and following up, a bigger billing or RCM job might make the process more linked. 

Compare a focused vendor with medical billing services and revenue cycle management services. Practices can also review the top revenue cycle management companies and best medical billing companies in the USA when considering a broader partner. Choose based on the work you need done, the reporting you will receive, and how responsibilities will be shared with your staff. 

FAQs 

What are the top companies for prior authorization?

Credex Healthcare, MyOutDesk, Integra Global Solutions, Hamly Business Solutions, Transcure, BillingParadise, AMBSI, and TaskUs are some choices for medical offices that want to hire outside help and offer publicly stated authorization services. Some providers offer authorization along with more general RCM or staffing. Before making a choice, look at the written prices, service scope, specialty fit, and reporting.

What do prior authorization services include?

As part of the service, you may be asked to check your status and make sure you meet the requirements of your insurance company, collect clinical papers, send in requests, follow up through payment websites or other channels, write down information about your approval, and keep an eye on ending dates or visit limits. Peer-to-peer reviews and complaints are also accepted by some businesses. Make sure you know what tasks are included and which ones your clinical team will still be doing.

How much does it cost to outsource prior authorization?

Prices can be set per authorization, based on the number of dedicated or shared staff members, or included with billing or RCM. A lot of businesses don’t put prices online. Get a written price based on your usage and workload, and make sure it covers follow-up, appeal support, setup fees, minimums, and overage charges.

How long does prior authorization take?

Timing depends on the payer, plan, service, how quickly you submit the request, and how complete it is. According to CMS-0057-F, some payers have up to 72 hours to make a standard request and seven calendar days to make an expedited request. Those dates are payment decisions; they don’t mean the request will be approved or that the provider has time to submit it.

What’s the difference between a prior authorization company and EviCore or CoverMyMeds?

A medical practice hires an outside service to help it submit, track, or manage requests. EviCore manages utilization on the payer side. Electronic prior authorization for medicines is linked to CoverMyMeds. When you search, the names may appear together, but they serve different functions.

Can a prior authorization company also handle denials and billing?

In addition to authorization support, some providers offer appeals, denial management, billing, or RCM. Others are more focused on processes for staffing or authorization. Check to see if the suggested contract includes work like following up on authorization denials, peer-to-peer coordination, claim repair, and appeals. Also, make sure you know who owns each task after a payer makes a decision.

Choose Support that Fits Your Workflow 

Before you compare prior authorization companies, you need to know where the work gets stuck: requirement checks, paperwork, submission, payer follow-up, or appeals. Make sure the provider’s services fit your specialty and the types of payers you work with. Then, get written confirmation of pricing, reporting, security, and handoffs.
