A clearinghouse sits between a practice and every payer it bills. Claims go out through it, rejections and remittances come back through it, and eligibility checks often run through it as well. Because it touches every dollar of revenue, a poor clearinghouse choice shows up as slow cash, avoidable rejections, and staff time spent working around problems. Yet many practices inherit their clearinghouse from their practice management vendor without ever evaluating it. This guide explains how to compare clearinghouses on the criteria that matter.
What a clearinghouse does
At its core, a clearinghouse receives claims from a practice in the HIPAA standard 837 format, checks them for formatting and basic content errors, translates them to each payer's specific requirements, and transmits them. It then returns acknowledgments, rejections, and, when the practice is enrolled, electronic remittance advice in the 835 format. Most clearinghouses also offer real-time eligibility verification using the 270 and 271 transactions, claim status inquiry, and electronic attachments. Some add patient statement printing, payment processing, and analytics.
The value a clearinghouse adds is in the middle steps: the quality of its claim scrubbing, the breadth of its payer connections, and the clarity of the feedback it gives staff when something is wrong.
Do you choose it, or does your vendor?
Three arrangements are common. Some practice management systems include a built-in clearinghouse owned by the same company; the practice has little choice but often gets tight integration. Some systems partner with one or more independent clearinghouses and let the practice pick from a list. Some systems can send to any clearinghouse through a standard file interface, which gives the practice full choice at the cost of more setup. Before comparing clearinghouses, confirm which arrangement your practice management system supports and what it costs to use a clearinghouse other than the default.
If the clearinghouse is bundled with your practice management system, you are still entitled to evaluate it. Rejection rates, ERA coverage, and support quality are measurable, and a poor result is a legitimate reason to negotiate or to weigh the bundled option against an independent one.
Comparison criteria
| Criterion | What to check | Why it matters |
|---|---|---|
| Payer connectivity | Direct electronic connections for your top twenty payers; whether any are routed through a second clearinghouse or dropped to paper | Indirect routing adds days and failure points |
| Claim scrubbing | Edits beyond format checks: payer-specific rules, coding edits, medical necessity checks; whether edits are updated when payers change rules | The difference between a rejection caught in seconds and a denial discovered in thirty days |
| ERA and EFT enrollment | Whether the clearinghouse manages payer enrollment for you and how long it typically takes | Enrollment delays are the most common cause of a slow start |
| Eligibility | Real-time and batch eligibility, payer coverage, and how responses display to front-desk staff | Front-end verification prevents back-end denials |
| Rejection workflow | How rejections are presented, whether they can be corrected and resubmitted in the clearinghouse or must go back to the practice management system | Determines how much staff time each rejection consumes |
| Reporting | First-pass acceptance rate, rejection reasons by payer, days to payment, aging of unacknowledged claims | You cannot manage what the clearinghouse does not report |
| Integration | Certified or supported integration with your practice management system; automatic posting of 835 files | Manual file handling is where errors and delays creep in |
| Support | Hours, channels, response times, and whether support staff can see your actual claims | Claim problems are time-sensitive |
Ask each candidate for its payer list and check it against your own top payers by volume, not by name recognition. A clearinghouse that connects directly to national payers but routes your largest regional plan through a partner may perform worse for you than one with fewer total connections.
Pricing models
Clearinghouses price in several ways, and the models produce very different totals depending on practice volume:
- Per-claim: a fee for each claim transmitted, sometimes with separate fees for ERA, eligibility, and attachments. Predictable per transaction; expensive at high volume.
- Per-provider per month: a flat fee for each rendering provider, usually with unlimited claims. Simple; can be costly for part-time providers.
- Tiered or bundled: a monthly fee for a block of transactions with overage charges. Good for stable volume; watch the overage rate.
- Percentage of collections: more common when the clearinghouse is part of a billing service. Aligns incentives but is usually the most expensive at scale.
Model the total annual cost under each candidate's pricing using your actual claim, eligibility, and ERA counts from the past year, and include setup fees, enrollment fees, paper claim fees, and any charge for statements or attachments. A quote that looks cheaper per claim can be more expensive once eligibility and ERA fees are added.
Security, compliance, and continuity
A clearinghouse handles protected health information for every patient the practice bills, so it is a business associate and must sign a business associate agreement. Beyond the agreement, ask about the clearinghouse's security program: independent audit reports, encryption of data in transit and at rest, access controls for its own staff, and its incident response process. Ask specifically about its recovery plan and how the practice would submit claims if the clearinghouse were unavailable for an extended period; recent large-scale outages in the industry have shown that a clearinghouse disruption can halt a practice's cash flow for weeks.
Clearinghouses conducting HIPAA standard transactions must also comply with the transaction standards and operating rules adopted under the administrative simplification provisions. A clearinghouse that keeps current with those standards protects the practice from transaction-level compliance issues.
A selection process that fits a small practice
- Pull a year of claim, ERA, and eligibility volume by payer from the practice management system.
- Confirm which clearinghouses your practice management system supports and the cost of each option.
- Request payer lists, pricing, sample reports, and a business associate agreement from two or three candidates.
- Check references with practices of similar size and specialty, asking specifically about enrollment time, rejection handling, and support responsiveness.
- Model total annual cost for each candidate using your actual volumes.
- Score the candidates on connectivity, scrubbing, workflow, reporting, integration, support, security, and cost, weighting the criteria by their effect on your revenue cycle.
- Plan the transition around payer re-enrollment, which is the step that determines whether the switch is smooth.
The best clearinghouse for a practice is the one that gets its specific claims to its specific payers with the fewest touches. Measuring that against your own data is the whole point of the exercise.
Common questions
Is a clearinghouse required to submit claims?
No. Practices can submit directly to payers that offer a direct submission portal or connection, and some payers accept paper. In practice, a clearinghouse is the only way to submit to many payers electronically from one place, and the HIPAA transaction standards apply to electronic claims regardless of the path.
How long does it take to switch clearinghouses?
The transmission setup is usually quick; the time-consuming step is re-enrolling for electronic remittance advice, electronic funds transfer, and in some cases claim submission with each payer. Enrollment timelines range from days to several weeks per payer, so a switch typically takes one to three months to complete fully.
What is a good first-pass acceptance rate?
Many practices target a clearinghouse-level first-pass acceptance rate above 95 percent, meaning fewer than five percent of claims are rejected before reaching the payer. The more useful number is the payer-level clean claim rate, which reflects both clearinghouse scrubbing and the practice's own data quality.
Does the clearinghouse need to sign a business associate agreement?
Yes. A clearinghouse creates, receives, maintains, and transmits protected health information on the practice's behalf, which makes it a business associate under HIPAA. Health care clearinghouses are also themselves covered entities under the rule when performing certain functions.
