15 Questions to Ask a Medical Billing Company Before You Sign

Signing with a medical billing company is one of the highest-stakes vendor decisions a practice makes — the right partner lifts collections and shrinks denials, while the wrong one locks you into a long contract while your AR quietly ages. The questions to ask a medical billing company before you sign are your best protection: they turn sales promises into verifiable numbers you can compare across vendors. This guide gives you 15 questions organized into four groups — performance, scope, compliance, and contract — with benchmarks for what good answers actually sound like and the red-flag answers that should end a sales call early. If you’d rather skip the vetting process, our medical billing services are built to stand up to every question on this list.

Why the Cheapest Percentage Fee Usually Costs More

Most billing companies charge a percentage of collections, not charges. That single fact makes the fee percentage the least informative number in any proposal — because what matters is what gets collected, not what percentage of it the vendor keeps. Do the math on a practice collecting $60,000 a month. Vendor A charges 4% but collects 85% of net collectible revenue: you keep $48,960 a month. Vendor B charges 6% but collects 97%: you keep $54,480 a month. The “cheap” vendor costs you $5,520 a month — over $66,000 a year — in revenue that never reaches your bank account. The 15 questions below are designed to surface exactly that gap: what each vendor actually delivers per dollar of fee, and whether their numbers survive scrutiny.

5 Performance Questions That Reveal True Billing Quality

Performance questions separate operators from order-takers. Every answer should come with a number, a timeframe, and a method — adjectives don’t collect revenue.

1. What is your first-pass claim acceptance rate?

The first-pass acceptance rate — the share of claims accepted on first submission — is the clearest single indicator of billing quality. Look for 95% or higher, with top performers at 98%+. Ask how the vendor measures it (across their full client base, not a hand-picked sample) and whether they’ll show you the report. If they can’t produce a number, they aren’t tracking it — which means nobody is accountable for it on your account either.

2. What is your average days in AR?

Days in accounts receivable measures how long it takes a practice to get paid. Well-run practices target under 35–40 days; anything drifting past 50 signals weak follow-up. Ask for the vendor’s average across clients and what share of their clients’ AR sits in the 90+ day bucket — that’s where revenue goes to die. A vendor with a decent average but a fat 90+ bucket is cherry-picking easy claims and ignoring the hard ones.

3. What is your monthly denial rate, and how quickly do you work denials?

Two numbers, one answer. The denial rate should sit in the single digits — for reference, more than 40% of US providers report denial rates of 10% or higher, so a partner operating well below that is earning their fee. And denials should be worked within 48 hours of receipt, not stacked for a monthly “denial day.” Ask whether they categorize denials by root cause and fix the upstream problem so the denial stops recurring — re-billing the same error is not denial management.

4. How — and how often — do you report on my practice’s performance?

You should see what was billed, collected, adjusted, and denied every month, in numbers you can understand without a decoder ring. Ask for a sample report before you sign. Good answers: weekly AR snapshots plus a monthly collections report, with access to a client dashboard you can check anytime. Red flags: quarterly reports, reports that bury adjustments, or dashboards that only show gross charges.

5. What is your net collection rate?

The net collection rate — collections as a percentage of net collectible revenue (after contractual adjustments, before bad debt) — is the number that determines your income. Strong billing companies collect 95–96% or more of what payers contractually owe. Ask precisely how they define it: vendors who define it loosely or refuse to commit to a number are telling you everything you need to know.

4 Scope Questions: What Are You Actually Paying For?

A percentage fee is meaningless without a defined scope. These questions pin down exactly what the fee covers — and what will show up as a surprise invoice later.

6. Exactly which services are included in my fee, and what costs extra?

Get the full scope in writing before you sign. The usual carve-outs that ambush practices later: credentialing and payer enrollment, eligibility verification, old-AR cleanup, clearinghouse fees, patient statements and collections, and postage. Neither model is inherently wrong — an itemized scope is. Ask for a line-item list of inclusions and exclusions attached to the contract.

7. Who actually works my claims — employees, subcontractors, or offshore staff?

Ask who touches your revenue cycle day to day: are they the company’s own trained employees, subcontractors, or an offshore team? Offshore billing isn’t automatically disqualifying, but it must be disclosed — and the vendor should be able to tell you who is accountable for your account, what certifications their coders hold (CPC or equivalent), and how quality is audited. “We have a team” is not an answer.

8. Do you handle credentialing and payer enrollment?

Credentialing is where new revenue quietly bleeds: commercial enrollment typically takes 90–120 days and Medicare 60–90, and every week of delay is unbillable. Ask whether credentialing and payer enrollment services are included in the fee or billed separately, who on their team owns the process, and how applications are tracked. A billing company that shrugs at credentialing will cost you months of unrecoverable revenue.

9. How do you handle old and aging AR?

Claims past 90 days need a different workflow than fresh claims — triage by filing deadline, batch payer calls, appeal escalation. Ask whether aging-AR recovery is part of the standard service or a separate engagement, and what their process is for claims approaching timely filing limits. If your practice already has old AR, ask specifically how they’d attack it in the first 90 days — and get the plan in writing.

3 Compliance and Data-Security Questions

Your billing company touches every patient’s protected health information. Compliance questions aren’t box-checking — vague answers here are a hard stop.

10. How do you protect my patients’ PHI?

Ask for their HIPAA policies, business associate agreement terms, and specifics on access controls: encrypted storage and transmission, role-based access, audit logging, and breach notification procedures. If any work is done offshore, ask how access is controlled across borders. The vendor should explain all of this in plain language. Evasive or “we’re fully compliant, don’t worry” answers mean they aren’t.

11. If we part ways, how do I get my data back — and who owns it?

Your billing data is your asset. Ask: in what format will you deliver my complete AR, claim history, and payer credentials if we terminate? How quickly? Is there a fee? Put the answer in the contract. Vendors that are vague about data handoff are usually planning to use it as leverage — a confident operator hands it over cleanly because their retention comes from performance, not hostage data.

12. How do you stay current with payer rules and code changes?

Payer policies, LCDs, and code sets change constantly — 2026 brought hundreds of CPT and ICD-10 changes alone. Ask how the team learns about changes, how quickly updates reach your claims, and who is responsible for charge-master updates. A serious vendor has a documented update process; a casual one finds out about rule changes from your denials.

3 Contract Questions Before You Sign Anything

Read the termination clause before the pricing page. Contract questions reveal whether the vendor earns your business monthly or locks it in legally.

13. How does your pricing work, and when does it change?

Get the pricing model spelled out: percentage of collections, per-claim flat fee, or per-FTE — and exactly what triggers a rate change. Does the percentage apply to gross or net collections? Are there minimum monthly fees that quietly raise your effective rate? Do add-on services have published prices? Compare any quote against 2026 norms in our medical billing outsourcing cost breakdown, and ask any vendor quoting well below market what’s been carved out of the scope.

14. What are the contract length, termination terms, and transition assistance?

Reasonable terms: 30–90 day termination for convenience, a defined transition process (AR data, payer credentials, documentation handoff), and no termination fee beyond a final month of service. Also ask about the onboarding timeline — a well-run transition takes 30–60 days, including a parallel run on new claims. Be wary of anyone promising a one-week switch, or anyone who can’t describe their transition process step by step.

15. Can you provide references from practices like mine?

Ask for two or three references in your specialty and size range — and actually call them. Ask the references about collections trends, denial rates, responsiveness, and how the vendor handled problems, not just whether they’re “satisfied.” A vendor with a strong book of business produces references eagerly. Stalling, cherry-picked mega-clients, or “our clients prefer privacy” is a signal.

Good Answers vs. Red Flags: A Quick Comparison

Use this table as a scorecard on sales calls. One red flag is a question; two or three is a pattern.

What you asked about	Good answer	Red flag
First-pass acceptance rate	95–98%, measured across the full client base, with the report to prove it	“Very high” with no number, or a rate quoted from a single best client
Days in AR	Under 35–40 days average, with a small 90+ day bucket	Can’t quote an average, or a ballooning 90+ bucket they wave away
Denial management	Single-digit denial rate; denials worked within 48 hours; root-cause fixes upstream	“We re-bill everything” — re-billing a coded error just gets denied again
Reporting	Weekly AR snapshots, monthly collections report, live dashboard access	Quarterly PDFs that show gross charges but bury adjustments
Scope	Itemized inclusions and exclusions attached to the contract	“Full-service billing” with credentialing, old AR, and eligibility quietly extra
Staffing	Named account team; certified coders; offshore disclosed with controls explained	Can’t say who works your account; offshore never mentioned until you ask
Data ownership	Full export in standard formats on termination, spelled out in the contract	Vague handoff terms or a fee to retrieve your own data
Contract terms	30–90 day termination for convenience; defined transition; no lock-in	12-month auto-renew with a 90-day notice window and steep termination fees
References	Two or three same-specialty references, offered before you ask twice	Stalling, mismatched mega-clients, or “our clients prefer privacy”

Frequently Asked Questions

What is the most important question to ask a medical billing company?

Ask for their first-pass claim acceptance rate and net collection rate with documentation. Those two numbers summarize everything: billing accuracy upstream and actual dollars recovered downstream. A vendor that documents 95%+ acceptance and 95–96%+ net collections has a quality operation; one that dodges the numbers is asking you to buy on faith.

What percentage should a medical billing company charge in 2026?

Most small-to-mid practices pay 3–8% of collections, with per-claim models running $4–$8 per claim. But the percentage alone tells you little: a 4% fee collecting 85% of your revenue costs you far more than a 6% fee collecting 97%. Compare the effective economics — fee plus collection rate — not the headline number.

How long does it take to switch billing companies?

A well-run transition takes 30–60 days: data and payer-access handoff, EHR integration, eligibility and charge-capture setup, and a parallel run on new claims while the old vendor winds down AR. Be wary of anyone promising a one-week switch — or anyone who can’t describe their transition process step by step.

Should I worry if a billing company uses offshore staff?

Not automatically — but it must be disclosed, and the vendor should explain their HIPAA controls, access restrictions, and quality audits in plain language. Offshore teams that are hidden until you ask, or covered by hand-waving about compliance, are the problem — not the geography itself.

What contract terms should I avoid with a billing company?

Avoid 12-month lock-ins with no performance-based exit, termination fees beyond a final month of service, auto-renewal clauses with narrow cancellation windows, and any ambiguity about who owns your billing data. Fair contracts let a vendor earn your business monthly — 30–90 day termination for convenience with defined transition assistance.
