Wiki 90853 (Group psychotherapy)

[soprano]

Does anyone know how many minutes one unit of this code is equal to? I don't see a time base in the CPT book. Do I bill one hour of 90853 at one unit or is this a thirty minute code and I should bill two units to equal one hour of group psychotherapy.

There is no time units associated with this code. It is billed as one unit without reguard to time/lenght of the session. Each member in the group may be billed separately at one unit.

Thank you, thank you

2 hour 90853 Group

We run 2 and 3 hour substance abuse groups. Does anyone know how to bill this to BCBS. If we use 90853 it is a unit of service, so we do not get paid for 2 hours or 3 hours.
HELP!!!
