Our local Medicaid has a policy on this. It requires a minimum of 30 minutes...
Countable Services
The following activities are countable services toward the 30-minute minimum requirement for CPO:
-Review of charts, reports, treatment plans, or lab or study results, except for the initial interpretation or review of lab or study results that were ordered during or associated with a face-to-face encounter.
-Telephone calls with other health care professionals (not employed in the same practice) involved in the care of the patient.
-Team conferences (time spent per individual patient must be documented).
-Telephone or face-to-face discussions with a pharmacist about pharmaceutical therapies.
