1What Is the A205 OHIP Code?

What is the A205 Code?

The A205 code is used for billing consultations in the field of obstetrics and gynaecology under the Ontario Health Insurance Plan (OHIP). OBGyn consultations typically involve addressing issues such as abnormal uterine bleeding, suspected endometriosis with chronic pelvic pain, or postmenopausal bleeding which might require an endometrial assessment.

Referrals for these consultations come from primary care physicians, who seek specialized evaluations that may also include advice on fertility or contraceptive counseling or follow-up for abnormal cervical cancer screening results. These nuanced cases often necessitate the skilled assessment of an OBGyn, making accurate billing under A205 crucial for appropriate compensation. However, this billing code might be missed if the consultation inadvertently falls under a general or repeat consultation without proper documentation to justify the comprehensive nature of service warranted by a referral.

  • Virtual Consultations:

    • A205 is eligible for virtual delivery and identified as A205A, strictly via video.

4What Your Clinical Note Must Show

1Documentation for A205 Billing

Ensure thorough documentation for billing A205, including:

  • Written referral note from the primary care physician or referring specialist.
  • Detailed notes of the consultation discussing the specific reason, history, assessments done, and any planned management or treatment.
  • Documentation of any cervical cancer screening specimen collection when performed.

5Weak vs. Strong Note Examples

The strong note clearly outlines the referral process, patient history, examination performed, and the outlined plan, meeting A205 requirements. The weak note lacks detail and context which could lead to misinterpretation or possible claim denial.

Weak Note

Patient referred by GP. Discussed symptoms of bleeding.

Strong Note

Patient referred by Dr. Smith for evaluation of abnormal uterine bleeding. Reviewed history of symptoms, including onset, duration, and prior interventions. Conducted a comprehensive pelvic exam and collected cervical screening specimen. Planned follow-up includes potential biopsy if bleeding persists.

  • Comprehensive history and clinical findings.
  • Documentation of the referral details with specifics.
  • Clarity on the plan going forward, tailored to the patient's findings.
