Updated: Ontario Prenatal Care Codes and Antenatal Forms

An updated guide on the use of Prenatal Care OHIP Billing Codes P003, P004 and P005. 

We often find there is some confusion among our physicians with the different types of OHIP billing codes for prenatal care visits. We have updated our quick reference guide to provide some clarity in order to help you bill more effectively. Below are the latest updates on prenatal care codes for billing: 

  • At the initial prenatal visit with your patient (i.e. major visit such as a physical assessment), you should bill with a P003 code. 
  • The following prenatal visits of these patients (i.e. minor visits) should be billed using a P004 code. 
  • The P005 code is billed when the antenatal preventative care assessment is completed. We recommend you complete the antenatal preventative care assessment during either the major visit (P003) or minor visit (P004) as you can bill it along with either of these two codes.

Reminders: Antenatal Forms  

The codes P003, P004, P005 and P008 are to be filled in the Ontario Perinatal Record (OPR) – previously known as the Antenatal Form. The form is effective July 1, 2017, and includes the following major updates: 

  • Expanded from 2 to 3 pages 
    The original two-page record has been expanded to three pages to allow for more thorough documentation of medical, genetic, and psychosocial  issues (this is the requirement for billing P005). 
  • Now a total of 5 pages 
    It now includes a page of mental health screening resources and a standardized postnatal visit record (for a postnatal visit, you bill P008). 

Updated sections & consolidations 

  • Updated genetic history and investigations 
  • Updated language respectful of gender identity and the multiple ways in which individuals may identify themselves as a parent 
  • Updated demographics to reflect newer methods of contact, planned place of birth, newborn care provider 
  • All lab and ultrasound tests are now on page 2 

Working with the Ontario Perinatal Record (OPR) 

The OPR contains:

  • A comprehensive section on immunizations
  • Prompts for special circumstances requiring time sensitive interventions 
  • Inclusion of mental health screening questions and tools 
  • Grouped and expanded discussion topics by trimester
