    Would I use modifier 26 for nerve conduction studies? Modifier 51 for mulitiple tests?

    you can bill for each nerve tested. bill the appropriate code just change the unit amount
    99503 &99504 are modifier 51 exempt
    for bilateral
    you would report the code twice and use LT and RT
    if you would like some paper work/documentation on this stuff email me and i will attach it in an email for you
    hope this helps

    Dear sir\madam,
    I have question on 99503 and 99504 CPT codes. Who can perform this both codes on patient house- respiratory therapist or Registered skilled nurse?. If it can be done by Registered skilled nurse as per physician advice means any problem on using these both codes?. Kindly give me a exact hours or minimum hours of treatment for these both codes. Shall we use these 2 codes along with S9124 or T1030 or T1031? Kindly help me and clarify for this questions as soon as possible. If you have any legal coding documentation for these 99503 and 99504, please kindly forward to email id- bharani.physiotherapist@gmail.com. kindly give me a solution. Thanks a lot.
