The question asked, verbatim: best medical billing services for medical clinics

Brands named, in the order the engine gave

1. Tebra mentioned
   Tebra (the old Kareo + PatientPop) - best fit for small independent and solo practices, 1-10 providers.
2. AdvancedMD mentioned
   The honest weakness: Tebra doesn't publish a first-pass claim rate the way athenahealth, AdvancedMD, or CareCloud do, and the outsourced billing is a partner, not Tebra itself - so you're really vetting that partner.
3. CareCloud mentioned
   The honest weakness: Tebra doesn't publish a first-pass claim rate the way athenahealth, AdvancedMD, or CareCloud do, and the outsourced billing is a partner, not Tebra itself - so you're really vetting that partner.
4. AdvancedMD RCM mentioned
   AdvancedMD RCM - the pick if you're a mid-size or multi-provider group that wants deep, configurable workflows and reporting.

The answer, as recorded

A caveat worth stating up front: most "top 10 medical billing companies" pages that come up in search are published by billing companies ranking themselves. So I'm weighting toward vendors with real scale, published performance numbers, and contracts you can actually verify - and I'd treat the rest as leads to audit, not recommendations. ## What I'd actually recommend, in order **1. athenahealth (athenaOne / athenaCollector)** - my default pick for most clinics. It's the one where the billing service and the EHR/practice management are genuinely the same system, and they publish hard numbers (98.4% first-pass acceptance, a rules engine of ~29,000+ payer rules maintained across their whole network). That network effect is the real product: payer rule changes get caught once and applied to everyone. Pricing is percentage-of-collections, roughly 4-8% of monthly net collections, negotiated - small groups under 3 providers land closer to 5-7%. Downsides: no public pricing, and the percentage model means you pay more as you grow. **2. Tebra (the old Kareo + PatientPop)** - best fit for small independent and solo practices, 1-10 providers. Built specifically for that segment rather than scaled down from enterprise. You can run billing in-house on their tools, or have Tebra match you to a partner billing company. The honest weakness: Tebra doesn't publish a first-pass claim rate the way athenahealth, AdvancedMD, or CareCloud do, and the outsourced billing is a partner, not Tebra itself - so you're really vetting that partner. **3. AdvancedMD RCM** - the pick if you're a mid-size or multi-provider group that wants deep, configurable workflows and reporting. Documented ~95% first-pass acceptance. Makes most sense if you're already on (or willing to move to) the AdvancedMD PM/EHR stack; standalone it's less compelling. **4. CareCloud** - worth a quote alongside AdvancedMD for the same mid-size segment. Publishes performance metrics, and they run their own offshore delivery, which usually shows up as lower quoted percentages. Get references from practices in your specialty. **5. A specialty-focused regional billing company** - genuinely often the right answer, and I'd rather you shortlist one than skip the category. If you're behavioral health, ortho, anesthesia, or oncology, a firm that only does your specialty will beat a generalist on modifier handling and payer appeals. AnnexMed (50+ specialties, 20+ years) and Medical Billers and Coders are the most commonly cited; treat them as starting points and make them prove it with references. **Skip:** the long tail of firms whose main visible asset is a blog post ranking themselves #1. ## Pricing reality check - Percentage of collections is the dominant model: **4-9%, with 5-7% typical**. Complex specialties (oncology with biologics, surgical coding with heavy modifier use) push 6-8%. - 1,000+ claims/month gives you real leverage to negotiate into the 4-7% band. - Flat per-claim runs roughly **$3-$10+**. Better if your average reimbursement per claim is high - you keep the upside. - In-house billing typically costs **8-12%** of collections all-in once you count salary, benefits, software, and turnover. That's the number to beat. ## Before you sign Ask every finalist for: **clean claim rate** (want >97%), **average days in A/R** (want <35), **first-pass acceptance rate**, and net collection rate. Get a free billing audit, references from two practices in your specialty and your size, and - the one people forget - confirm **who owns your data and what happens to open A/R if you terminate**. Also check whether the percentage applies to gross or net collections, and whether patient payments and capitation are in the base.
