Is anyone familiar with United Healthcare denying a 99397 dx V70.0 routine medical exam as max met.. up against a service provided by a GYN office 99397 dx V72.31 routine gyn service??. I billed a 99397 with dx V70.0 and it is denying as max met due to a GYN exam that pt had at another office....and the GYN office billed it as 99397 dx V72.31. Thank you.
