1What Is the C675 OHIP Code?

Understanding the C675 OHIP Code

The C675 code is used by cardiologists to bill for limited consultations concerning hospital in-patients. This service is often required when there's a need to address a specific cardiac concern, such as evaluating pre-operative risk or deciding on treatment for an arrhythmia prior to discharge. Unlike comprehensive consultations, this code is intended for situations where a full cardiovascular assessment is not necessary, focusing instead on targeted clinical questions.

This code might be overlooked due to misconceptions about the requirements for a consultation or a lack of awareness that focused cardiac inquiries can be billed separately. Proper documentation of the clinical question and rationale for the consultation is essential to ensure compliance and appropriate reimbursement.

3Eligibility Requirements

Eligibility Requirements for C675

  1. Consultation Setting: This code is applicable for limited cardiology consultations while a patient is in a hospital setting as an in-patient.

  2. Virtual Delivery: C675 may be rendered as a virtual service via video, billed as C675A. Telephone consultations do not qualify as a Comprehensive Virtual Care Service under this code.

  3. Frequency Restrictions:

    • One service is allowed per two consecutive 12-month periods for the same patient, physician, and diagnosis.
    • One service every 12 months for a different, clearly defined, unrelated diagnosis.
  4. Submission Instructions:

    • Use diagnostic code 428 when submitting claims.
    • For emergency or out-patient scenarios where the physician is not on duty in an emergency department, refer to the General Listings.

4What Your Clinical Note Must Show

1Documentation for C675 Billing

Comprehensive clinical records must detail the focus of the consultation.

  • Specific cardiac question prompting the consultation.
  • Assessment and recommendations made during the consultation.
  • Explicit documentation if the consultation is conducted via virtual video.

5Weak vs. Strong Note Examples

The strong note succeeds by clearly defining the specific cardiac issue, the assessment made, and actionable recommendations, while the weak note lacks specificity and context.

Weak Note

Patient seen for cardiac evaluation. Discussed treatment options.

Strong Note

Patient admitted for hip surgery; consultation requested to assess cardiac risk.

Pre-operative evaluation focused on recently diagnosed atrial fibrillation.

Recommendations included anticoagulation evaluation and rhythm monitoring before proceeding with surgery.

  • Specific inquiry focus
  • Clear assessment results
  • Recommendations for further management

6Common Reasons This Code Is Missed

1
Incomplete Documentation
Failure to document the precise cardiac question or recommendations could result in claim denial.
2
Misunderstanding Frequency Limits
Billing more frequently than allowed under the code's frequency limitations leads to rejections.
3
Incorrect Setting or Submission
Not differentiating between hospital in-patient and out-patient settings, or using incorrect diagnostic codes, may result in claim issues.
4
Overlooking Virtual Care Restrictions
Attempting to bill a phone consultation under this code, which does not meet virtual care eligibility, can lead to rejection.
