Whenever you generate billing in the Manage Billing section, TherapyPM generally batches the sessions that fall within the selected date range. Each line item contains multiple sessions.
However, you can still review the included sessions included in the system. 
- Click on the Claim Number (or) select the checkbox next to the preferred claim.
- Choose Show Details from the dropdown below the table.
You can now view all the sessions associated with that batch.
