Problem:
A substantive response to my classmate below:
The Organ or Disease /Oriented Panels subsection (80047-80081) are grouped to the laboratory work that was ordered by the physician for a diagnosis of or screening for diverse diseases or conditions. Categories of tests can be performed together using automated equipment depending on the situation or disease. A good example: A mother going for her first obstetric visit and the physician is acquiring that she needs to have laboratory tests performed to ensure that the appropriate ante partum care was provided. Code 80055 states that an obstetric panel would be performed during the patient first obstetric visit. Assigned panel codes, each test that is listed in the panel description has to be complete. All development of panels saves a facility from having to report them separately. Also, you can never assign modifier -52 with a panel. Example: If all of the tests were in a obstetric panel were completed except the syphilis test, you wouldn't be able to report 80055 with modifier -52.
