Use the following CPTs to handle billing for time spent with a group / family of patient members. CPT code 90846 This can be used if your provider is performing Family Psychotherapy without the patient being present. However, your documentation has to really be able to support the fact that this family therapy session was not to treat issues the family might be facing due to the patient's issues. This is to be used specifically (and documented) when your patient will clearly benefit from their family undergoing this session. CPT code 90847 Unlike 90846, use this when the patient is present. You won’t get as many push backs or denials as the patient is present (e.g. couples therapy) CPT code 90849 Use this only if your therapist is using this strategy to modify the family behaviors in relation to the patient. Again, the documentation/treatment plan has to support the fact that this is medically necessary for the patient.  This Multiple-Family Group Psychotherapy code is covered by most insurance plans but has to be abetted by good documentation. CPT code 90853 This CPT code is to be used for Group Psychotherapy. Note that this is not the same as a Multiple-Family Group (90849). When your provider is holding a session with a group (whatever the size might be, reasonably so) and is in the process of examining the issue(s) of each individual in the group, this code can be used. However, the code cannot be used for general therapy sessions. The group has to be put together for the treatment plan of the patient members. If you ever were to bill for this, you can use 90853 to report per-session services. This is applicable for each group member.
