1What Is the A595 OHIP Code?

The A595 billing code, specific to rheumatology, is used for limited consultations that require less time and focus on a specific issue. It typically involves tasks such as interpreting a single autoantibody result or determining if a joint issue is inflammatory.

Limited consultations are less time-intensive than full consultations, making them suitable for straightforward cases that don’t need a comprehensive assessment.

Physicians often overlook A595 when the consultation, while direct, still requires a defined level of expertise. Ensuring that a referral genuinely meets the criteria for a limited consultation is crucial.

3Eligibility Requirements

To bill for the A595 code, the consultation must follow a written request from a referring physician, nurse practitioner, or certain dental surgeons in connection with specific conditions. It should focus on a singular issue rather than a comprehensive assessment. A595 can also be rendered virtually through video, not telephone.

Consultations are limited to one per two consecutive 12-month periods for the same patient, physician, and diagnosis, with exceptions for clearly unrelated diagnoses. Incorrectly meeting these requirements leads to a reduced assessment fee.

4What Your Clinical Note Must Show

1Referral Requirements

The limited consultation must follow a written referral.

  • Referring physician or nurse practitioner must file the referral.
  • In the case of dental-related consultations, a dental surgeon's referral is needed.
2Consultation Limits and Context

Ensure eligibility for billing under A595 for limited services.

  • One service per two consecutive 12-month periods for the same diagnosis and patient.
  • Service must be rendered by a consultant physician due to the complexity or uniqueness of the case.

5Weak vs. Strong Note Examples

The strong note clearly outlines the referral details and specific focus of the consultation, whereas the weak note lacks detail and specificity.

Strong Note

Patient referred by Dr. Smith for an interpretation of ANA results.

Review and confirmation of non-inflammatory pathology.

  • Specific referral details from Dr. Smith included.
