In the below example, the individual charge lines total 0.8 units at $80. Roll-up logic will bill 0.7 units at $70 on the claim. Therefore, during the billing process, a "variance" charge will deduct –0.1 unit at –$10 from the encounter. This ensures that the $70 expected reimbursement from insurance can be posted to a $70 balance in NextGen® Enterprise PM. Otherwise, a $70 reimbursement on an $80 balance would leave a balance.

   - Charge 1
    
     - CPT4 / Price: 90862 / $100.00 per unit
 
     - Base Minutes: 60
 
     - Start/Stop Times: 10:00 – 10:21 = 21 minutes
 
     - Quantity/Units: 0.4 unit
 
     - Charge Amount: 0.4 unit X $100.00 = $40.00
 
    
 
  
  
   - Charge 2
    
     - CPT4 / Price: 90862 / $100.00 per unit
 
     - Base Minutes: 60
 
     - Start/Stop Times: 11:00 – 11:21 = 21 minutes
 
     - Quantity/Units: 0.4 unit
 
     - Charge Amount: 0.4 unit X $100.00 = $40.00
 
    
 
  
  
   - Charge Totals: 90862; 0.8 unit; $80.00
 
   - Roll-up Totals: 21 minutes + 21 minutes = 42 minutes = 0.7 unit
 
   - Roll-up Claim: 90862; 0.7 unit; $70.00
 
   - Variance: –0.1 unit X $100.00 = –$10.00
