Primary Care Coding Alert

Question: How should we bill Medicare for obtaining a diagnostic Pap smear? The patient has postmenopausal bleeding and is not in a high-risk category. I'm concerned that Q0091 is not appropriate because the code definition explicitly says "screening."

Answer: You are correct. Q0091 (screening Papanicolaou smear; obtaining, preparing and conveyance of cervical or vaginal smear to laboratory) is assigned only for a screening study. In this instance, you would report only the office visit code that reflects the level of E/M service provided, i.e., 99201-99205, office or other outpatient visit, new patient; and 99211-99215, office or other outpatient, established patient.
 
CPT provides a code for diagnostic Pap smears, 88150 (cytopathology, slides, cervical or vaginal; manual screening under physician supervision), which coders might be tempted to assign. This code should not be used, because  it includes cytopathological examination of the smear, a service usually provided by a pathologist, not the family physician.
