Medical Billing Cost Summary

Outsourced medical billing typically costs 4–7% of net collections for small-to-medium practices using percentage-of-collections pricing — the most common model. A practice collecting $80,000/month pays $3,200–$5,600/month for billing services. This is almost always cheaper than an in-house billing staff member when total employment costs, technology, and turnover risk are factored in. The ROI of outsourcing is driven by three sources: lower cost-to-collect, faster payment (shorter Days in AR), and higher net collection rate from denial management expertise.

The 3 Medical Billing Pricing Models Explained

Percentage of Collections

Most Common Model

Typical Rate: 4–7% of net collections (range: 2.5–9%)

The billing company charges a percentage of what is actually collected — not what is billed. This model aligns incentives perfectly: the billing company earns more when they collect more. It is the most transparent model because cost scales with revenue performance.

Example: Practice collecting $100,000/month at 5%

Monthly billing cost: $5,000 | Annual: $60,000

Best for: Most practices, any specialty. Preferred when you want aligned incentives and transparent cost relative to performance.

Flat Monthly Fee

Typical Rate: $500–$3,000/month per provider

A fixed monthly fee regardless of collections volume. Provides cost predictability but removes the performance incentive from the billing company — they earn the same whether collections are high or low.

Best for: Predictable-volume practices that want fixed overhead. Watch for contracts with minimum billing volumes that effectively create a percentage model anyway.

Per-Claim Pricing

Typical Rate: $3–$7 per claim submitted

Charges per claim submitted rather than per dollar collected. This model favors low-complexity, high-volume practices (primary care, urgent care). For specialists with complex claims and more denial management, per-claim pricing often underestimates cost and incentivizes submitting more claims rather than collecting more revenue.

Best for: High-volume, low-complexity practices where claim volume is predictable and denial rates are low.

Average Medical Billing Rates by Specialty

Specialty Typical Range Key Cost Driver
Primary Care / Family Medicine 3–5% High volume, lower complexity E&M coding
Internal Medicine 4–6% Medicare complexity, CCM/AWV coding
Orthopedic Surgery 5–7% Global periods, implant billing, prior auth
Behavioral Health 5–8% Parity compliance, session billing complexity
Interventional Pain 5–8% PA volume, LCD compliance, procedure coding complexity
Dental 4–6% CDT vs. CPT complexity, annual maximum tracking
DME Suppliers 6–9% PDAC documentation, prior auth, competitive bidding

In-House Billing vs. Outsourced Billing: True Cost Comparison

Cost Component In-House Billing Outsourced Billing
Staff Cost (1 biller, 2-provider practice) $55,000–$75,000/yr salary + benefits $0 direct staff cost
Benefits & Payroll Taxes (~28%) $15,400–$21,000/yr $0
Practice Management Software $3,000–$6,000/yr Usually included
Clearinghouse Fees $1,200–$3,000/yr Usually included
Turnover & Training Cost $10,000–$25,000 per turnover event $0 (absorbed by company)
Service Fee (practice at $80K/mo, 5%) $0 $48,000/yr
Estimated Annual Total $84,600–$130,000+ $48,000–$55,000

Note: Outsourced billing often also delivers 10–20% higher net collections through denial management and AR follow-up — a revenue benefit not reflected in the cost comparison above.

Medical Billing Cost FAQ

Medical billing costs vary by pricing model and practice size. Percentage of collections is the most common model — rates typically range from 2.5% to 8% of net collections, with most practices paying 4–6%. A practice collecting $80,000/month pays $3,200–$4,800/month for outsourced billing. Flat-fee models range $500–$3,000/month per provider. Per-claim pricing ranges $3–$7 per claim. The right model depends on your specialty complexity and billing volume.
A fair percentage for medical billing depends on specialty and complexity: 3–5% for high-volume primary care; 5–7% for surgical specialties or complex billing environments (interventional pain, behavioral health, DME). Rates above 8% are above market for ongoing billing — though higher rates may be justified for old AR recovery projects. Rates below 3% should be evaluated carefully, as very low rates often indicate minimal denial management or AR follow-up included in scope.
For most practices with fewer than 10 physicians, yes — significantly cheaper. A full-time biller costs $55,000–$75,000 in salary plus benefits ($15,000–$21,000), software ($3,000–$6,000), clearinghouse fees ($1,200–$3,000), and carries turnover risk ($10,000–$25,000 per turnover event). Total in-house cost for a 2-physician practice: $85,000–$130,000/year. Outsourced billing at 5% for a practice collecting $80K/month: $48,000/year — with better performance and no turnover risk.
Standard medical billing services typically include: claim preparation, scrubbing, and electronic submission; ERA/EOB processing and payment posting; denial management and appeals; AR follow-up by payer and age bucket; patient statement generation; and monthly reporting. Services that often cost extra: provider credentialing and enrollment; prior authorization services; old AR recovery (pre-transition AR); and specialty-specific coding consultation. Always confirm the full scope in writing before signing a contract.
