AOP analysis


Outpatientization – evaluating opportunities and risks

Check for context factors and specification of GOP digits to be billed (EBM)

Functions of the AOP Analysis

The AOP analysis checks for the presence of procedures according to the AOP catalogue as well as hard and soft context factors on the basis of the § 21 data records. Justification texts are output for cases that were admitted as inpatients for medical or social reasons to ensure the success of the treatment. If AOP measures are available, GOP numbers incl. surcharges and supplements are shown, which can be billed in the case of outpatient service provision. This information is supplemented by the presentation of costs and revenues incurred by outpatient service provision in the inpatient setting.

These tool is usable free of charge for hospitals – incl. export!
