The vendor versions of this article list virtues. This one is built from what burned buyers say they wish they had checked, which makes the uncomfortable items the important ones.
1. Live Client References
Ask for two current clients of your size and specialty, and treat reluctance as an answer.
2. Exactly Which Tasks Stay With Your Team
"Full-service" is doing heavy lifting in most pitches. Owners report discovering after signing that eligibility checks, claim corrections or patient calls quietly bounce back to their own front desk. Get the task split in writing: who verifies, who corrects rejections, who calls patients, who works credentialing paperwork.
3. Who Owns Credentialing and Enrollment, in Writing
Payer enrollment under the vendor's control is the single biggest switching cost buyers report. Practices that kept credentials under the provider describe vendor changes as painful but doable; practices that did not describe being stuck. Separately, credentialing handled badly costs real money in delayed and denied claims. Whoever does the work, ownership stays with you.
4. Every Fee Trigger Behind the Headline Price
The expensive surprises are rarely in the headline rate. They arrive later: per-encounter surcharges past a volume threshold, new charges appearing mid-contract, costs rising while support goes quiet. Ask for the complete fee schedule: what triggers extra charges, what the percentage applies to if there is one, and what changes the vendor can make unilaterally. Percentage arrangements also have a legal dimension: some states restrict fee-splitting for billing services, so check your state's rules.
5. What the Monthly Report Actually Shows
A one-page summary with a collections total is the first symptom of shallow follow-up. The report you want shows denial reasons, aging buckets, and small-balance behavior, monthly, in a form someone in your practice will actually read. Practices that stay happy with outsourced billing consistently describe themselves as still watching; oversight is a feature of every model that works.
6. Exit Terms and Data Access
Decide the divorce terms at the wedding. Where does your claims history and AR data live, in what format do you get it, and how long is access guaranteed after termination? The standard advice from billers who have unwound these relationships: audit and export your AR before the relationship ends, because access has a way of shrinking afterwards.
7. How Denials and Small Balances Get Worked
The most expensive failure in owner accounts is invisible: clean claims collected, denials and small patient balances left unworked, discovered as a quiet percentage of collections that never arrived. Ask specifically: who works the denial queue, on what cadence, and at what balance size does follow-up stop? Then verify it in the reporting. Our guide to the denial reasons that repeat shows what a worked queue looks like.
8. Benchmarks to Anchor the Conversation
Two category numbers buyers commonly anchor on: net collection rate in the mid-to-high 90s is the health check practices cite, and monthly reporting with denial and AR detail is the floor, not a premium feature. Any partner should be comfortable being measured against both.
How myMedCrew Answers the Same Checklist
Fair is fair: the eight checks, answered. References on request. The task split is explicit because the model is a named person: a pre-vetted billing specialist working inside your own PMS or billing system on the queue you assign, so the work is visible in your system rather than reported from outside it. Credentials and payer enrollment stay in your name. Rates are flat, hourly and published, billed on hours worked. Reporting reflects your own system's data because the work happens there. If you leave, your data was never anywhere else. Denials and balances are worked as assigned queues with write-offs approved by you.
The full model lives at medical billing services, and the wider decision has its own guide: in-house vs outsourced medical billing.
Frequently asked questions
How do I choose a medical billing company?+
Run eight checks before signing: live references, the exact task split, credentialing ownership, all fee triggers, reporting depth, exit and data terms, how denials and small balances are worked, and your state's rules for billing arrangements. Reluctance on any of them is information.
What questions should I ask a medical billing company?+
Who works my denial queue and how often, what does the monthly report show, what triggers charges beyond the headline rate, who owns payer enrollment, which tasks remain with my staff, and how do I get my data if we part ways.
What is a good net collection rate?+
Practices commonly anchor on a net collection rate in the mid-to-high 90s as the sign billing is being worked properly, alongside AR aging kept under control.
What are red flags when evaluating billing services?+
Reluctance to provide references, contracts silent on exit data access, pricing that only quotes a headline number, one-page monthly reports, and vagueness about which tasks bounce back to your team.
