Say goodbye to your confusion over screening guidelines. To code a well-woman exam correctly, you've got to know two key concepts: how Medicare and private payers' guidelines differ, and when you should separately code breast/pelvic exams and Pap smears. Best bet: 1. Break Out Services for Medicare If the ob-gyn provides a complete well-woman exam for a Medicare patient, you should report G0101 (Cervical or vaginal cancer screening; pelvic and clinical breast examination) for the breast and pelvic exams, and bill the patient for the noncovered part of the exam using 99387 (Initial comprehensive preventive medicine evaluation and management of an individual including an age- and gender-appropriate history, examination, counseling/anticipatory guidance/risk factor reduction interventions, and the ordering of appropriate immunization(s), laboratory/diagnostic procedures, new patient; 65 years or older) or 99397 (Periodic comprehensive preventive medicine re-evaluation and management of an individual including an age- and gender-appropriate history, examination...established patient; 65 years or older). When the physician also obtains a Pap smear, use Q0091 (Screening Papanicolaou smear; obtaining, preparing and conveyance of cervical or vaginal smear to laboratory), says Carol Pohlig, BSN, RN, CPC, senior coding and education specialist at the University of Pennsylvania department of medicine in Philadelphia. Remember that you can also report a new or established patient E/M code (99201-99215) in addition to G0101 and Q0091 if the physician addresses significant problems at the time of the well-woman visit, Pohlig says. But the physician must have documented a separate and distinct E/M service, and you must attach modifier 25 (Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure or other service) to the E/M code. For example, the physician performs the well-woman exam but also evaluates and manages the patient's ongoing dysfunctional uterine bleeding. Important: ICD-10: Avoid High-Risk Coding If the patient is high-risk, you can bill the Pap smears annually. To classify a patient as high-risk, you will have to use V15.89 (Other specified personal history presenting hazards to health; other) for medical justification of a screening Pap smear, Larabee says. "Medicare has specific requirements that have to be met for a patient to be considered high-risk," Larabee adds. For this reason, your physician should supply secondary diagnoses to explain why the patient is high-risk. These diagnoses include: ICD-10: 2. Rely on CPT Codes for Private Insurers Although most commercial payers follow Medicare's lead when setting coding policies, many accept neither G0101 nor Q0091 for well-woman visits. This is because the Medicare codes only include a physical examination but do not cover history or counseling. In those cases, you may report one of CPT's preventive-medicine codes (99381- 99397), depending on your payer's policies, Pohlig says. Coding tip: If the patient is established, you should report one of these codes: In some cases, private payers will reimburse for handling the Pap specimen. If so, you can also report 99000 (Handling and/or conveyance of specimen for transfer from the physician's office to a laboratory). Typically, you'll link ICD-9 code V72.31 to 99000. Important: Note:
