Normally kinesiotape is used in conjuction with Neuromuscular Re-education. IE. Tape prior to patellar tracking exercises and bill a 97112. I do not believe you can bill for taping a shoulder blade then having him walk out of your office.
I have been told by some chiros/therapists that there are "strapping codes" that can be used and they charge (get ready for this, are you sitting down) $100 for application of the tape and get reimbursed.
