In NextGen® Enterprise PM, the Units and Price for a behavioral health charge is calculated during charge posting as follows:
 
  - The total time in minutes is calculated from the start and stop times entered for the charge. 
Stop Time – Start Time = Total Time
 
  - The charge units (quantity) are then calculated by dividing the total time by the base minutes defined for the SIM code. Any additional minutes are rounded using the base minute rounding method configured for the payer. 
Total Time / Base Minutes = Units
   Note: The SIM code Base Minutes is either a ‘standard’ value (15, 30, 60, 240) or a ‘custom’ value. The payer Base Minute Rounding Method is either a ‘default’ method or a ‘custom’ method configured for the base minute value.
   
 
  - The charge price is then calculated by multiplying the units by the unit price defined for the SIM code. 
Units X Price = Extended Price
