I found this by accident trying to find a 1500 free medical form but wasn't looking forward to filling it out by hand. We are a dental office just starting to use medical coding for new procedures. Plus I'd like to put our new patient forms on our website for patients to fill in electronically! Thank you!

This program is easy to use, has the forms I needed. Easy fill, print and save. Great online program. Accomplished exactly what I needed to without having to search all over for the forms.

Simple, no BS Simple, fast, easy. No BS like so many other "free" pdf add-ons. No issues upload, editing, or resaving any of my content. No changes in the PDF while getting in or upload.

Payment issue dealt with swiftly After both my cards being declined to register my subscription, I went onto the online support chat. Kara was super helpful and quick to deal with my issue - very professional and friendly. Kara was very generous in giving me three free days and advised within that time to try my payment again after 24 hours. Thank you Kara for taking the stress away and resolving my issue fast. Morven

no problems so far no problems so far, only thing I don't like is that the forms you search for come from google and isn't always the same thing you are searching for.
