Understanding Billing Cost Models
Most medical practices have no idea what they actually spend on billing. The costs are spread across staff salaries, benefits, software subscriptions, clearinghouse fees, statement printing, and the hidden cost of denied and uncollected claims. When you add it all up, many practices are spending 10 to 15 percent of collections on billing — while believing they are spending far less.
The medical billing cost percentage matters because it directly impacts your take-home revenue. A practice collecting $100,000 per month that spends 12 percent on billing keeps $88,000. That same practice switching to a 4 percent outsourced model keeps $96,000 — an extra $96,000 per year without seeing a single additional patient.
The first step toward controlling billing costs is understanding exactly what you are paying today. The calculator below will help you see the numbers clearly, but first, let us break down the two primary billing cost models and what drives the difference between them.
Percentage-Based vs Flat Fee
Percentage-based billing charges a fixed percentage of what the practice actually collects. This model aligns the billing company's incentives with the practice's revenue — the more the practice collects, the more the billing company earns. Typical percentages range from 3 to 7 percent of collections depending on specialty, volume, and payer mix.
Flat fee billing charges a fixed amount per claim submitted, regardless of whether the claim is paid. Per-claim fees typically range from $4 to $10 per claim. While this sounds cheaper on paper, it creates a perverse incentive — the billing company gets paid for submitting claims, not for collecting on them. A flat fee model rewards volume of submissions, not quality of collections.
There is also the in-house model, where the practice employs its own billing staff. This is the most expensive option for most practices once you account for salary, benefits, training, software, office space, and management overhead. A single full-time medical biller costs $45,000 to $65,000 in total compensation, and most practices need more than one person to cover the full billing cycle.

What 3-7% Actually Includes
When a reputable revenue cycle management company quotes 3 to 7 percent of collections, that percentage should cover the entire billing lifecycle. This means charge entry, claim scrubbing, electronic submission, payment posting, denial management, patient statement generation, and accounts receivable follow-up. If any of these functions are excluded or billed separately, the advertised percentage is misleading.
The percentage varies based on several factors. High-volume primary care practices with clean commercial payer mixes typically fall at the lower end — 3 to 4 percent. Surgical specialties, multi-provider groups, and practices with significant out-of-network volume fall at the higher end due to the additional complexity of coding, authorization management, and payer negotiation.
What matters more than the exact percentage is the net collection rate the billing company achieves. A company charging 5 percent that collects 98 percent of allowed amounts delivers far more revenue than a company charging 3 percent that only collects 88 percent. Always evaluate billing cost in the context of collection performance — the cheapest option is almost never the most profitable.
Hidden Costs Most Practices Miss
The biggest hidden cost in medical billing is not a line item on any invoice — it is uncollected revenue. A billing operation that fails to follow up on denied claims, does not appeal underpayments, or lets accounts receivable age beyond 90 days is costing the practice far more in lost collections than it saves in billing fees. The difference between a 90 percent and a 97 percent net collection rate on $1.2 million in annual charges is $84,000.
For in-house billing operations, the hidden costs are even larger. Employee turnover is a constant drain — replacing a medical biller costs $5,000 to $10,000 in recruiting, hiring, and training. Software licenses, clearinghouse fees, and electronic remittance subscriptions add another $500 to $1,500 per month. Paid time off, sick days, and benefits add 25 to 35 percent on top of base salary.
There is also the opportunity cost of management attention. Every hour a practice owner spends managing billing staff, resolving billing issues, or reviewing aging reports is an hour not spent on patient care or practice growth. For physician-owned practices, this management burden translates directly into reduced clinical productivity and lower overall revenue.
REL1EF's Pricing Model
REL1EF uses a percentage-of-collections model with no setup fees, no monthly minimums, and no long-term contracts. The percentage is based on the practice's specialty, volume, and complexity — and it covers the entire revenue cycle from charge capture through final payment posting. There are no hidden fees for clearinghouse transactions, statement mailing, or credentialing support.
What makes REL1EF's model different from other percentage-based billing companies is the OON recovery layer. For practices with out-of-network claims, REL1EF operates a dedicated negotiation and appeals process that recovers revenue most billing companies write off. This OON upside is not reflected in the calculator above — it represents additional revenue above and beyond what the practice is currently collecting.
The fastest way to see the actual financial impact is through REL1EF's free A/R recovery trial. REL1EF works your existing aged receivables at no upfront cost, recovers money that is currently sitting uncollected, and the practice keeps everything above the fee. The trial results give you a concrete, dollar-figure answer to the question of what better billing is worth to your practice.
