Hi guest!
Great question. I don't believe E1700 is an appropriate code for JVA, as JVA is more of a diagnostic system rather than a treatment/rehab.
I believe products such as the Therabite would be what is considered a Jaw motion rehabilitation system, here is a link to info on it:
http://www.craniorehab.com/therabite-jaw-motion-rehab-system.htmlAnd here is a medical policy from Aetna that covers Jaw motion rehabilitation systems:
http://www.aetna.com/cpb/medical/data/400_499/0412.htmlThe only indication listed that it would be covered/considered medically necessary for is "to treat mandibular hypomobility caused by radiation in persons with head and neck cancers."
TMD is listed as experimental & investigational
As for a code for the JVA, we are not aware of a specific medical code for it. Some offices have used 77077, however the description on that code is: Joint survey, single view, 2 or more joints (specify)
So, it may not be appropriate as the JVA is not an xray.
The closest code we have been able to locate is:
76536 - Diagnostic ultrasound exam of the head and neck area
But also, keep in mind that most insurers list JVA as "experimental & investigational" as well so no coverage is offered for it.
Hope this helps, have a great day!
