1What Is the H104 OHIP Code?

The H104 billing code applies to re-assessments conducted by family medicine practitioners within emergency departments or Hospital Urgent Care Clinics. This code is relevant for reassessments that occur at least two hours after an initial assessment, indicating further care or investigation is necessary.

During an emergency department visit, family physicians frequently need to reassess patients after treatment or upon receiving new test results. The H104 code ensures that these crucial follow-ups are appropriately compensated. Missing or incorrect usage of this code can result in lost revenue for services that deserve reimbursement.

3Eligibility Requirements

Eligibility for billing the H104 code is based on specific criteria as outlined in the OHIP Schedule of Benefits:

  • The service must occur at least two hours after the original assessment or a prior re-assessment and must be necessary due to an indicated need for further care.
  • It should not be billed for discharge assessments, upon the patient's admission by the emergency physician, or if the reassessment leads directly to a referral for consultation.
  • The re-assessment service under H104 is limited to three occurrences per patient per day and two per physician per patient per day. Services exceeding these limitations are ineligible for payment.

Additionally, proper time recording is essential, including the start and end times of the service on the patient's medical record. Failure to include these details will render the service unpayable.

4What Your Clinical Note Must Show

1Service Time Documentation

Ensure that the medical record contains the following:

  • Start time of the re-assessment service
  • End time of the re-assessment service

5Weak vs. Strong Note Examples

The strong note succeeds because it provides a detailed account of the clinical reasoning behind the reassessment, specific improvements or actions taken, and accurately records the time, maximizing eligibility for remuneration. The weak note falls short by lacking specific details and time documentation.

Weak Note

Reviewed patient. Pt stable. Reassessed.

Strong Note

Reassessed the patient two hours post-initial assessment owing to persistent symptoms. Necessary adjustments in care plan based on test results indicating elevated markers. Documented time of reassessment as follows:

  • Start: 15:00
  • End: 15:30

6Common Reasons This Code Is Missed

1
Failure to Document Time
The absence of documented start and end times in the medical record leads to non-payment.
2
Assuming Discharge Assessments are Covered
Misinterpreting re-assessment as including discharge assessments can result in claims being denied.
3
Exceeding Allowed Number of Re-assessments
Billing more than two per physician per patient per day or more than three per patient can result in denied claims.
4
Lack of Medical Necessity Documentation
Failing to document the medical necessity for the reassessment.
