I created a website for searching ICD-10 codes: https://fasticd10.com. I really think this is the best free search tool out there, for the following reasons:

1. It is clean, simple, and easy to use
2. It has predictive search (get results as you type)
3. It learns the codes that people choose and ranks them more highly (intelligent search)
4. It gives you the ability to copy and paste codes into your application.

Please let me know your feedback. If you like the website, please share the link with your colleagues!

I also created FastCPT.com for searching CPT codes.

Thanks!
