Single Base Unit Anesthesia Charge per Encounter

The Single base unit Anes. charge per encounter option in Practice Preferences > Charge Entry controls whether base units are saved on all anesthesia charge lines, or on the first charge line only.

When this check box is selected, the base units are saved only on the first anesthesia charge line entered on the Charge Posting window for the encounter.

The total anesthesia units for a charge are calculated as follows: [Base Units + Time Units + Modifier Units = Total Units]

Base Units are defined for the SIM code in the Service Items library.

Time Units are calculated based on the Anesthesia Minutes Per Unit and Anesthesia Rounding Method defined for the payer in the Payers master file.

Modifier Units are defined in the Claim Modifiers library.

Using the above example setup where both anesthesia charges are entered on an encounter, and the total time entered on each charge is 60 minutes, the base units for each charge is determined by the Single base unit Anes. charge per encounter setting.
