Physician billing services are outside companies that handle some or all of a practice’s revenue cycle: charge entry, coding, claim submission, payment posting, denial follow-up, and patient billing. The right vendor can cut days in A/R and recover denials your team never had time to work. The wrong one hides problems behind a monthly summary until the cash stops coming in.

What Do Physician Billing Services Actually Cover?
Scope varies a lot between vendors, so get it in writing. A full-service arrangement usually includes:
- Eligibility and benefits checks before visits
- Coding or coding review
- Claim scrubbing and submission
- Payment posting from ERAs and paper EOBs
- Denial management and appeals
- A/R follow-up on unpaid claims
- Patient statements and patient balance calls
- Credentialing, sometimes as a separate service
Many problems later on come from something both sides assumed the other was doing. Patient statements and credentialing are the usual gaps.
Questions to Ask Before You Sign
- How is the fee calculated? Percentage of collections, per claim, or flat monthly. If it’s a percentage, confirm exactly which collections count. Does it include patient payments, refunds, or payments from claims billed before the vendor started?
- Who works your account? A named team that knows your specialty, or a general queue?
- What happens to denials? Ask what percentage they appeal, how fast, and whether low-dollar denials are written off without asking you.
- What reports do you get, and how often? At a minimum: days in A/R, A/R aging by payer, denial rate by reason, and net collection rate.
- Who owns the data? If you leave, do you get a full export of claims, payments, and notes?
- How do they handle compliance? Ask about coding audits, HIPAA safeguards, and whether they sign a business associate agreement.
- What’s the exit clause? Notice period, and whether they keep working the claims they submitted after the contract ends.
Red Flags in Billing Contracts
- Long auto-renewing terms with steep early termination fees.
- Fees on money the vendor didn’t work, such as patient copays collected at your front desk.
- No minimum reporting commitments in the contract.
- Vague offshore arrangements without clear HIPAA controls.
- “Guaranteed” collection increases without a baseline measured from your own data.
In-House vs. Outsourced: Run the Real Numbers
Before comparing vendors, compare outsourcing to your current setup with the full cost, not just a biller’s salary. Our in-house vs. outsourced RCM cost comparison walks through the categories. Whatever you decide, the metrics in our days in A/R benchmarks give you a baseline to hold any vendor to.
Frequently Asked Questions About Physician Billing Services
How do physician billing services charge?
Usually as a percentage of collections, a per-claim fee, or a flat monthly fee. Contracts differ on which collections count toward a percentage fee, so read that definition closely.
What reports should a billing company provide?
At a minimum: days in A/R, A/R aging by payer, denial rate by reason, and net collection rate, delivered monthly and broken out by provider and payer.
Should a billing company sign a business associate agreement?
Yes. A billing vendor handles protected health information on the practice’s behalf, so a HIPAA business associate agreement is standard.
What happens to my claims if I leave a billing company?
It depends on the contract. Check whether the vendor keeps working claims it submitted, for how long, and whether you get a full data export.
