K010 – Group psychotherapy - additional units
OHIP Consultation & Visit Premium Codes Code — CONSULTATIONS AND VISITS · Schedule of Benefits
This code is for additional units of group psychotherapy provided to 2 to 12 people. It is billed per member for each additional unit of service after the initial units (covered by codes such as K019, K020, etc.) have been billed. A maximum of 6 units of K010 may be claimed per patient, per day. A unit is defined as a half-hour or major part thereof, subject to the time-keeping requirements specified in the Schedule of Benefits (see ).
When to Use
- Use K010 to bill for each 30-minute block of group therapy beyond the initial units covered by K019 or K020.
- Apply this code when the total duration of the group session exceeds the base time allotted by the primary psychotherapy code, provided the session involves 2 to 12 participants.
Common Pitfalls
- Billing K010 without first billing the base code (K019 or K020) will result in a rejection, as K010 is strictly an 'additional unit' code.
- Exceeding the daily maximum of 6 units of K010 per patient will trigger automatic claim rejections.
- Failing to document exact start and end times in the chart is a common audit failure that leads to full recovery of the K010 fee.
Billing Tips
- Ensure the total time billed across K019/K020 and K010 reflects the actual duration of the group session, keeping in mind that a unit is defined as a half-hour or major part thereof (at least 16 minutes).
