1What Is the A680 OHIP Code?

The A680 OHIP billing code is used for the initial assessment of substance abuse disorders in family medicine. It typically covers a comprehensive evaluation of a patient's substance history, risk of withdrawal, comorbid mental health conditions, and the development of a treatment plan, including the potential initiation of opioid agonist therapy. This service is crucial for creating an effective treatment strategy tailored to the patient's needs.

Misunderstanding or overlooking the eligibility requirements can lead to missed billing opportunities. A680 is limited to one claim per patient per physician or practice group unless a period of 12 months has passed since the physician last provided an insured service to the patient. Additionally, it cannot be billed for smoking cessation assessments, for which other codes like A957, K039, or E079 should be used.

3Eligibility Requirements

Eligibility for A680

  • Frequency: A680 can be billed once per patient per physician or practice group, unless 12 months have elapsed since the last insured service was rendered to the patient by the same physician.
  • Exclusions: A680 is not eligible for smoking cessation assessments; codes A957, K039, or E079 should be utilized instead.
  • Practice Group Definition: A practice group includes any physicians within the same billing group or those who share access to the patient's records and are co-located.
  • Service Details: The calculation of service time for A680 excludes any time devoted to other services or procedures for which separate payment is made and non-patient-facing activities like reviewing charts or documentation.

4What Your Clinical Note Must Show

1Documentation Requirements for A680

Ensure that the following details are clearly documented in the patient's medical record:

  • Complete substance use history including types of substances used and duration.
  • Assessment of withdrawal risks and any comorbid mental health issues.
  • Detailed treatment plan, potentially including initiation of opioid agonist therapy.
  • Confirmation that this assessment is the first in 12 months by the physician or practice group.

5Weak vs. Strong Note Examples

The strong note succeeds because it details specific aspects of the patient's condition and the service provided, crucial for effective documentation and accurate billing, whereas the weak note lacks specificity and thoroughness.

Weak Note

Patient seen for substance issues. Discussed treatment. No further details.

Strong Note

Completed a comprehensive assessment for substance abuse. Reviewed patient's history of alcohol and opioid use over the past 2 years, noted potential withdrawal symptoms, and discussed related anxiety disorder. Initiated a treatment plan with possible opioid agonist therapy.

  • Substance use history with specific substances and usage duration.
  • Assessment of mental health status and withdrawal risk.
  • Developed a detailed, patient-specific treatment plan.
