    HEY PATRICIA--Check this out...maybe this is what he is talking about??

    Computer-assisted surgery (CAS) is an adjunct process used in conjunction with certain orthopedic procedures. CAS encompasses both image-guided and imageless forms. Utilizing such tools as imaging, markers, reference frames, intraoperative sensing, and computer workstations, computer-assisted navigational procedures increase visualization of the surgical field and aid in precise navigation with minimally invasive approaches. CAS may involve guidance based on intraoperative images obtained by such means as fluoroscopy or ultrasound. It may also involve preoperative images or imageless navigation utilizing angles and measurements (kinematics) for anatomy determination. The key components of CAS include planning, registration, and navigation. Planning typically includes preoperative and/or intraoperative images taken by computed tomography, magnetic resonance, and/or fluoroscopy, and involves the creation of three-dimensional graphic models of the patient's anatomy. The patient-specific surgical plan and images are then used during surgery to guide the surgeon by combining these with intraoperative navigation capabilities. Optical targets, or trackers, such as digitizing or LED-equipped probes, are attached to points on the bone anatomy or to surgical tools. An optical camera tracks the position of these for accurate navigation and measurement in relation to any bone or instrument movement as the surgery is performed. The software in these navigational systems matches or "registers" the position of the patient on the operating table to the geometric description of the bony surface derived from the images already used to plan the surgery. Multiple images are simultaneously displayed on the monitor. The "virtual" tool trajectory that corresponds to the tracked tool movements is displayed over the previously saved views in real-time as the surgeon operates. Report 20985 for imageless CAS, 20986 for CAS with image guidance based on images obtained intraoperatively, and 20987 for those obtained preoperatively.~ ~~. ~~

    Mary - I knew I could count on you!!!
    My doc has yet to respond actually - I do have a meeting with him today and will pick his brain while I am there! - I would definately place a bet that you are correct though! - Makes sense... he's our Hip and Knee specialist who does mostly THR's / TKR's and resurfacing procedures. Considering the patient in question has end stage osteoarthritis - he may be using this preoperatively (pre-THR... forget the TKR momentarily) to measure amount of joint space loss / bone loss. I keep you updated!!!

    I use this code alot for my docs. Do you have Encoder Pro or access to see the primary codes? Since this is an "add on" code, there is about a three page list of primary procedures that these codes can be billed with. If you dont have Encoder, send me your fax # via private message and I'll fax this to you.

    Have a great hump day!!

    Hey Mary...
    Well - long story short - YES - YOU ARE TOTALLY CORRECT!! - But he didn't need this auth'd with the TKR. lol- (Not a clue where they got that from...)
    He does this preoperatively in some cases to measure bone loss. Thanks again!!
