Choosing a billing company is a bigger decision than most software purchases: the right partner lifts collections for years, and the wrong one costs you revenue you'll never see itemized. This comparison covers the 10 best medical billing companies in 2026, organized by what each is genuinely best at. Full disclosure: this guide is published by Astral Medical Billing, and we've included ourselves where we believe we honestly fit. The rest of the list is who we'd actually shortlist if we were you.

1. Astral Medical Billing: Best for Small Practices
We built our service around the practices the big RCM firms treat as small accounts: solo practitioners and 1-5 provider groups. That means billing inside your existing EHR (you keep your data and logins), a named team instead of a ticket queue, credentialing included in the relationship, and monthly reporting against the benchmarks that matter: 95%+ clean claims and days in AR under 40. Specialty depth in mental health, physical therapy, chiropractic, urgent care, and laboratory billing. Start with a free billing checkup.
2. BellMedEx: Best for Pricing Transparency
One of the few companies that publishes its rates, which makes them the easiest to budget against. Strong small-practice focus, wide specialty page coverage, and solid review volume. If published pricing is your top criterion, start here and compare quotes against it.
3. CureMD: Best One-Vendor EHR + Billing Combo
A long-established EHR and practice management company whose billing service is tightly integrated with its own software. If you want one vendor for the whole stack and are open to using CureMD's EHR, the integration is genuinely convenient. If you want to keep your current EHR, weigh that coupling carefully.
4. Medical Billers and Coders: Best Breadth of Coverage
Operating since 1999 with one of the widest footprints in the industry across specialties and states. A network model: your work is matched to billers with your specialty background. Good fit if your specialty is unusual and you want someone who has seen it before.
5. MedCare MSO: Best for Labs and Multi-State Groups
Strong laboratory and imaging billing practice alongside standard physician RCM, with state-by-state operational coverage. Publishes a starting rate, which helps comparison shopping.
6. Plutus Health: Best for Behavioral Health and ABA
Deep sub-specialty focus in behavioral health, ABA therapy, and ambulatory surgical centers, with heavy investment in automation. Suits mid-size behavioral organizations more than solo therapists.
7. Tebra (formerly Kareo): Best If You're Already on Tebra
Tebra's billing network pairs its practice management software with independent billing companies. If your practice already runs on Tebra software, using a billing partner from its ecosystem keeps everything in one workflow.
8. AdvancedMD RCM: Best Software-Integrated RCM
Similar logic to CureMD and Tebra: if you run AdvancedMD, its in-house RCM service works inside the system your staff already knows. The integration is the value; switching EHRs just to get it rarely makes sense.
9. Coronis Health: Best for Larger Multi-Specialty Groups
A roll-up of established billing companies with dedicated divisions for anesthesia, emergency medicine, labs, and facility billing. Built for organizations with volume; small practices are not the sweet spot.
10. R1 RCM: Best for Hospitals and Health Systems
Enterprise revenue cycle at hospital scale, including full department outsourcing. If you're an independent practice, this isn't your tier, but if you're evaluating for a hospital or large health system, R1 belongs on the list.
How to Actually Choose
- Match to your size. A 2-provider practice at an enterprise firm gets an enterprise firm's smallest team. Pick a company whose core client looks like you.
- Keep your EHR. Companies that bill inside your system leave you in control of your data; companies that move you into theirs create switching costs you'll feel for years.
- Demand the numbers. Ask every candidate: what clean claim rate and days in AR do you hold clients to, and what monthly reports will I get? Benchmarks are 95%+ and under 40 days (check your current numbers with our clean claim and AR days calculators).
- Understand the fee. Percentage of what: gross charges or actual collections? What's included, and what costs extra? Our pricing guide covers the models and the traps.
- Ask who works your denials. Claims submission is table stakes. Denial follow-up and AR work is where billing companies actually differ.
FAQs
What does a medical billing company cost?
Typically 3-8% of monthly collections, depending on specialty, volume, and scope. See the full breakdown in our medical billing cost guide.
Which billing company is best for a small practice?
One whose core clients are small practices, that works inside your existing EHR, and that includes credentialing and denial work in the base fee. That's the model we built at Astral, and BellMedEx is a fair comparison point.
Should I choose my EHR vendor's billing service?
If you love the software, integration is a real advantage. The risk is coupling: leaving the billing service later can mean leaving the EHR too. Independent billing companies that work inside any EHR avoid that lock-in.
How long does switching billing companies take?
30 to 60 days for most practices, run in parallel with your current process so cash flow doesn't pause.
What questions should I ask on a sales call?
Who exactly works my account? What clean claim rate and AR days will you commit to? Is the percentage on collections or charges? What happens to my data if I leave? Is there a termination fee?
