1What Is the A353 OHIP Code?

What is A353?

A353 is a billing code used by urologists in Ontario for specific assessments. It involves a detailed history and examination that focuses on the presenting urological complaint, such as haematuria, a scrotal mass, or obstructive urinary symptoms. These assessments are crucial in diagnosing and planning treatment pathways.

This billing entry is not commonly missed but can be overlooked when the specific history and examination requirements are not fully met or properly documented. A clear understanding of the clinical criteria ensures compliance and appropriate compensation for the time and expertise provided.

3Eligibility Requirements

Eligibility for A353

Requirements for Specific Assessment (A353):

  • Location: Must be rendered in a place other than the patient’s home.
  • Components: Requires a comprehensive history of the presenting complaint and a detailed examination of the affected part(s). This could involve diagnosing conditions, excluding diseases, or assessing function.
  • Frequency Limit: This billing code is limited to one assessment per patient per physician within a 12-month period. However, you may bill it twice if:
    1. The second visit is for a clearly different diagnosis unrelated to the first, or
    2. It is a hospital admission assessment and at least 90 days have passed since the initial assessment.
  • Documentation: Time of service must be recorded, noting when the service started and ended to ensure payment.
  • Virtual Delivery: The assessment can be conducted virtually if needed, billed under A353A.

4What Your Clinical Note Must Show

1Documentation Requirements

To ensure proper billing and avoid remittance issues, ensure the following documentation is captured:

  • Full patient history related to presenting urological issue.
  • Detailed examination findings of the affected urological part(s) or system(s).
  • Time records indicating start and end of the service.

5Weak vs. Strong Note Examples

The strong note succeeds by detailing the patient’s symptoms, specific examination findings, and considerations for further diagnostics. The weak note lacks detail and fails to justify billing at the specific assessment level.

Weak Note

Patient presented with urinary symptoms. Performed assessment.

Strong Note

Patient presented with visible haematuria for two days. A complete history of urinary patterns was gathered. Examined the abdomen and pelvis, noting tenderness in the right pelvic area without palpable masses.

  • Reviewed medical history for kidney stones.
  • Discussed potential need for further diagnostics, including ultrasound.
