Patient is regularly seen for migraines by one provider and receives Botox injections for migraines by separate provider, same office same specialty. It appears a follow up appointment had been scheduled at patient's previous E/M encounter. Between the completed visit and the upcoming visit patient was scheduled for the Botox injection, looks like it was cancelled and rescheduled, twice. The Botox appointment was 4/27 and the pre-scheduled follow up was 5/4. In the follow up note it is documented that there was improvement with the pain from Botox but not at goal and increased oral rx by half current dose. Provider feels they should be able to bill the follow up because it was a follow up for migraine medication and not the Botox injection. If the Botox is part of the treatment is it still not considered related, regardless of the management of oral medication?
