Finding the correct code for gait analysis can be difficult. The one point I want to make is if you are going to bill and code for gait analysis, make sure to document. Listen, you may know how to do it but I suggest you have some sort of reference or use a computer, because if you do not then there is a good chance you have to pay it back. This is a good book with details on how to do gait analysis.
Now if you are going a visual gait analysis with video: 97750
Now if you are using computerized gait analysis the code is 96000-96004
Again remember document document document
