Key Takeaways
- Ask every vendor 15 specific questions covering performance, operations, and business terms. Write down the answers and compare side by side.
- Demand KPI benchmarks in your SLA: 95%+ first-pass clean claim rate, under 5% denial rate, under 40 days in AR, 95%+ net collection rate.
- Red flags that mean walk away: guaranteed results before reviewing your data, pricing below 3% with no explanation, no dedicated account manager, long lock-in contracts with no performance clauses.
- Specialty fit matters more than any feature list. A generalist billing company will underperform in cardiology, behavioral health, or any specialty with distinct coding and payer rules.
- Protect your exit before you need it: 30 to 90 day termination notice, data return within 30 days, and 60 days of transition assistance in writing.
Most guides on choosing a medical billing company read like they were written by someone selling billing services. Lists of “features to look for” – experienced team, advanced technology, transparent reporting. Every vendor claims all of them. None of it helps you tell a good partner from an expensive mistake.
This guide takes the opposite approach. Instead of what to look for, it focuses on what to verify, what to demand in writing, and when to walk away. If you work through it before signing, you will know more about your prospective vendor than most of their current clients do.
The 15-Question Diligence Checklist
Ask every vendor these questions. Write down the answers. Compare them side by side. The vendors worth hiring will answer directly; the ones to avoid will deflect.
Performance questions
- What is your average first-pass clean claim rate across all clients? Demand 95% or higher.
- What is your average client denial rate? Demand under 5%.
- What is your average days in accounts receivable? Demand under 40 days.
- What is your net collection rate – the percentage of collectible revenue you actually collect? Demand 95% or higher.
- Can you show me anonymized reporting samples from a client in my specialty?
Operations questions
- Who is my day-to-day contact, and what is their response time commitment?
- How many clients does each account manager handle?
- What is your average time from contract signing to first clean claim submission? Under 30 days is standard; over 45 is a red flag.
- Which EHR and practice management systems do you work in, and will you work inside mine or require a migration?
- Who works my denials – a dedicated specialist or whoever is available – and what is your appeal success rate?
Business questions
- What exactly is included in your fee, and what costs extra? Get the full schedule in writing: setup fees, statement fees, appeal fees, credentialing fees.
- What are your contract terms – length, renewal, termination notice, and performance clauses?
- Do you provide a signed Business Associate Agreement before handling any patient data?
- Who owns my data, payer contracts, and credentialing records if we part ways?
- Can I speak with two current clients in my specialty?
Question 15 is the single most revealing. A vendor with happy specialty clients will connect you within days. A vendor that stalls, offers only “testimonials,” or provides references outside your specialty is telling you something.
Red Flags in the Sales Process
Watch for these during evaluation. Any one of them is grounds for serious concern; two or more means walk away.
Guaranteed results without reviewing your data. No vendor can promise collection increases before analyzing your claims, payer mix, and denial patterns. Guarantees before diligence are sales tactics, not commitments.
Pricing below 3% with no explanation. At that price, the math only works with offshore-only staffing, selective billing of easy claims while denials pile up, or hidden fees surfacing later. Ask what is excluded. Our outsourcing cost guide breaks down what realistic pricing looks like by model.
No dedicated account manager. If your claims go into a general queue and escalations take days, you do not have a partner – you have a vendor. Demand a named contact with a response-time commitment.
Vague denial management process. “We handle denials” is not a process. Ask who works them, what the appeal turnaround time is, and what percentage of appeals succeed. If the answers are vague, denials will fall through the cracks.
Long lock-in contracts with no performance clauses. A 24-month auto-renewing contract with steep exit penalties and no performance guarantees protects the vendor, not you. A confident company offers termination with reasonable notice and ties continuation to results.
“We work with every specialty.” Deep specialty expertise matters – cardiology coding, behavioral health payer rules, and DME documentation requirements are genuinely different disciplines. A vendor claiming equal mastery of all of them has shallow expertise in most.
No reporting samples. Any established vendor can show anonymized dashboards or benchmark data. Refusal to share them means either they do not track performance or the numbers are bad.
Pressure to sign quickly. Artificial urgency on a contract that governs your revenue cycle is a negotiating tactic. A vendor worth hiring will give you time for diligence.
The KPI Benchmarks to Demand in Your SLA
Do not accept verbal promises about performance. The benchmarks below should appear in your Service Level Agreement with defined remedies if the vendor misses them.
| KPI | Benchmark to demand | Why it matters |
|---|---|---|
| First-pass clean claim rate | 95% or higher | Claims accepted without rework; the single best predictor of cash flow health |
| Denial rate | Under 5% | The percentage of claims denied on first submission |
| Days in AR | Under 40 days | How fast earned revenue becomes collected revenue |
| Net collection rate | 95% or higher | Percentage of collectible revenue actually collected |
| Charge entry turnaround | 24-48 hours | How fast charges become submitted claims |
| Payment posting turnaround | 24-72 hours | How fast received payments hit your books |
| Appeal turnaround | 5-10 business days | How fast denied claims get worked, not just noted |
| Inquiry response time | Same business day | How fast your account manager responds |
Ask the vendor to commit to these in writing with a cure period and termination right if they consistently miss. Vendors who perform will agree; vendors who will not commit are telling you their numbers do not hold up.
Specialty Fit: Why Generalists Bleed Specialty Revenue
A billing company that handles family practice, cardiology, orthopedics, and behavioral health with the same team and the same workflows will underperform in all four. Specialty billing is not generic claim submission with different letterhead.
Cardiology requires mastery of catheterization coding, modifier 25/59/57 judgment calls, and payer-specific medical necessity rules. Behavioral health lives and dies on session documentation, authorization management, and payer carve-outs. DME billing has entirely different documentation and delivery-confirmation requirements. Physical therapy runs on the 8-minute rule and unit calculations that generalists routinely get wrong.
When evaluating vendors, ask:
- How many current clients do you serve in my specialty?
- What specialty-specific certifications does the team hold?
- Can you describe the top three denial reasons for my specialty and how you prevent them?
- Will the people working my claims specialize in my specialty, or rotate across all clients?
If the answers are generic, your specialty revenue will subsidize their learning curve.
Contract Terms That Protect You
The contract is where buyer protection becomes real. These are the clauses to negotiate before signing.
Term and termination. Favor 12-month initial terms with 30 to 90 day termination notice. Avoid auto-renewal beyond 12 months without written consent. Most important: include termination for cause tied to the KPI benchmarks above – if the vendor misses agreed targets for two consecutive quarters, you can exit without penalty.
Fee transparency. The contract must itemize every fee: the base percentage or flat rate, plus setup fees, statement fees, appeal fees, credentialing fees, and any per-claim charges. Our outsourcing cost guide details the fee structures to expect and the hidden charges to watch for.
Data ownership and return. Your patient data, payer contracts, credentialing records, and claims history belong to you. The contract should require the vendor to return all data in usable electronic format within 30 days of termination, at no charge.
Business Associate Agreement. Required under HIPAA before any patient data changes hands. It must cover breach notification procedures and data return or destruction obligations.
Transition assistance. Require the vendor to cooperate with your successor for at least 60 days after termination – transferring open AR, sharing denial worklists, and briefing the incoming team. Without this clause, switching vendors means starting from zero on every open claim.
Liability for errors. Clarify who bears the cost of billing errors – particularly upcoding or compliance violations the vendor introduces. The vendor should carry errors and omissions coverage.

The weighting reflects what actually drives results: specialty expertise and committed KPIs matter triple because they determine whether the vendor can perform; everything else supports that foundation.
The Bottom Line
Choosing a billing company is a revenue decision disguised as a vendor decision. The vendor you pick will touch every dollar your practice earns. Evaluate accordingly: verify performance claims against benchmarks, demand commitments in writing, check specialty references, and protect your exit before you need it.
