Free Tools for Medical Practices
Calculators and checkers built by the billing team and the lab at CCL Billing. They run in your browser: nothing you enter is stored or sent anywhere, and there is nothing to sign up for.
The Tools
Medical Billing Calculators
Denial rate, clean claim rate, first-pass resolution, net collection rate, days in A/R, A/R over 90 days, cost to collect, timely filing deadlines and no-show cost. Each result is set against the benchmark practices are measured by.
Medical Website Accessibility Checker
Automated WCAG 2.1 AA checks for any page of a practice website: missing text alternatives, low contrast, unlabeled form fields and more, each mapped to the success criterion it fails.
Using and Citing the Tools
The tools are free for any practice, consultant or student to use. If you write about them or link to them, please cite the page and the date you used it, for example: CCL Billing, Inc., “Free Medical Billing Calculators,” cclbilling.com/medical-billing-calculators.html, accessed November 2026.
The benchmarks behind each calculator, and how each metric is defined, are set out in our guide to medical billing metrics and KPIs. The accessibility checker tests against the W3C Web Content Accessibility Guidelines 2.1; what the federal rule requires of practice websites is in our Section 504 guide.
Medical societies, practice-management associations and consultants are welcome to share either tool with their members. If you would like a version on your own site with a credit link, ask us.
Want Someone to Read the Numbers With You?
A baseline review puts your own claims next to the benchmarks, and an accessibility scan puts your own website next to the standard. Both come back in writing.
