1What Is the A586 OHIP Code?

What is A586?

The A586 billing code is assigned for repeat consultations within the field of pathology. This typically involves a pathologist reassessing a patient's existing problem upon receiving a new written referral after the patient has received interim care from another healthcare provider. Common scenarios include transfusion medicine or inherited metabolic disorders requiring a second opinion after a change in the patient's condition or care plan.

This code is particularly significant in laboratory medicine contexts where a patient's diagnosis may evolve, necessitating additional expert consultation to tailor ongoing treatment plans. It is essential to understand the specific criteria and documentation requirements to ensure proper billing and reimbursement.

3Eligibility Requirements

Eligibility for Billing A586

To bill A586, the following eligibility requirements must be met as per the OHIP Schedule of Benefits:

  • Written Request Requirement: A new written request from a referring physician, nurse practitioner, or dental surgeon is mandatory. This document must be kept in the consulting physician's medical records if the consultation does not occur in a hospital, long-term care institution, or multi-specialty clinic with a shared medical record system.
  • Frequency Limit Exclusion: Repeat consultations are not limited by the standard frequency limits, ensuring flexibility in receiving necessary repeat evaluations.
  • Virtual Delivery: While A586 can be delivered virtually, it is only eligible for billing if provided via video, not telephone, under comprehensive virtual care services.

Failure to meet these criteria may result in the consultation being downgraded to a lesser assessment fee.

4What Your Clinical Note Must Show

1Necessary Documentation for A586

Ensure the following documentation is accurate and complete to qualify for A586:

  • A copy of the written request for consultation signed by the referring provider.
  • Placement in the consulting physician's medical record, unless records are shared at the point of care.

5Weak vs. Strong Note Examples

The strong note succeeds by specifying the receipt of a new referral and detailing assessment changes based on recent patient history. The weak note lacks specificity and context.

Weak Note

Reviewed lab results for inherited metabolic disorder. Further analysis and recommendations provided.

Strong Note

Conducted comprehensive review following new referral.

Re-assessed patient's condition post-transfusion in compliance with repeat consultation requirements.

  • New referral included analysis of previous care interventions.
  • Recommendations updated based on latest results and patient response to interim treatments.

6Common Reasons This Code Is Missed

1
Lack of New Referral
Submitting a repeat consultation without a new written request from the referring physician is a common mistake leading to denied claims.
2
Incomplete Documentation
Failing to maintain a copy of the new referral in the medical record as per OHIP guidelines can result in reduced fees.
3
Incorrect Billing for Virtual Consultations
Billing a phone consultation as A586, despite its eligibility only for video, will cause claim rejection.
