1What Is the A236 OHIP Code?

The A236 billing code is utilized by ophthalmologists for repeat consultations under the Ontario Health Insurance Plan (OHIP). This code applies when a patient is referred back to the ophthalmologist due to the same presenting problem after interim care was provided by another physician. For example, a patient whose glaucoma or retinal condition necessitates further specialist input after management by their general practitioner or another specialist may be eligible for this service.

This repeat consultation must be based on a new written referral, ensuring that each consultation is justified and medically necessary. Given the critical nature of eye health and potential changes in the patient's condition, ophthalmologists find this code particularly valuable for continuous and informed patient care.

Despite its importance, the A236 code is often missed due to inadequate documentation of the new referral or misunderstanding of the repeat consultation criteria. A thorough understanding of the code's requirements ensures accurate billing and optimized patient care.

3Eligibility Requirements

To bill for a repeat consultation using the A236 code, several eligibility criteria must be met:

  • New Written Request: Each repeat consultation requires a new written request from a referring physician, nurse practitioner, or dental surgeon, which must be kept in the medical record of the consulting ophthalmologist. This documentation is crucial unless the service is provided in settings with common medical records such as hospitals or multi-specialty clinics.
  • Same Presenting Problem: The repeat consultation must address the same presenting problem for which the initial consultation was performed.
  • Interim Care: The patient must have received care from another physician between the initial and repeat consultations.
  • Virtual Care: This service can be delivered via video under the code A236A; telephone consultations are not eligible.

Failure to adhere to these requirements could lead to a reduction of the payable amount to that of a general or specific assessment fee.

4What Your Clinical Note Must Show

1Documentation Requirements for A236

Ensure all necessary documentation is recorded and maintained to support billing for a repeat consultation.

  • Keep a copy of the new written request from the referring provider in the patient's medical record.
  • Document that the consultation is addressing the same problem as before.
  • Note the interim care provided by another physician prior to the repeat consultation.
  • Ensure all virtual consultations are conducted via video, as telephone consultations are ineligible.

5Weak vs. Strong Note Examples

The strong note succeeds by providing detailed clinical context and documenting the specifics of the referral and prior management, which is critical for justifying the repeat consultation.

Weak Note

Repeat consultation performed. Patient followed up after seeing another doctor. Referral in chart.

Strong Note

Conducted repeat consultation for evaluation of patient's glaucoma. Patient referred back after receiving management from general physician for interim pressure checks. New referral received from Dr. Smith, including changes in patient's visual field status, necessitating further specialist intervention.

  • Documented all relevant historical and current clinical details.
  • Included specifics of the interval management provided by the referring physician.

6Common Reasons This Code Is Missed

2
Misunderstanding of Repeat Consultation Criteria
Confusion over what constitutes a repeat consultation leads to improper billing.
3
Failure to Use Video for Virtual Consults
Billing for telephone consultations under this code is not permitted.
4
Lack of Interim Care Details
Not documenting the interim care received by the patient from another provider can result in claim downgrades.
5
