K005A: Primary Mental Health Care

Primary mental health care: individual assessment and treatment of mental or emotional problems by a family physician, billed per half-hour unit.

Not payable the same day as a consultation or other assessment by you to the same patient unless the two services have clearly different diagnoses (GP55, A21).
Units are ½ hour or major part: 1 unit = at least 20 minutes, 2 units = 46, 3 units = 76, 4 units = 106, then every 30 minutes more (GP55).
Count consecutive time in direct contact with the physician in person, excluding other separately billed services and chart work (GP54, GP55).
Record start and stop times in the chart, or the service is not eligible for payment (GP7).
Under 20 minutes is not this service; bill the assessment you actually provided (GP55).

AT3: Usually means it was billed as virtual care (K300A/K301A) and OHIP found no existing patient-physician relationship, such as an in-person visit with you in the past 24 months (AT3 guide; A66).
EH2: The health card version code doesn't match OHIP's record; get the current version code and resubmit (EH2 guide).
VJ7: The claim reached OHIP more than three months after the service date; resubmit as stale-dated only if it was first sent on time (VJ7 guide; GP9).
VH8: The date of birth doesn't match OHIP's record for the health number; correct it and resubmit (VH8 guide).
EQE: The physician isn't registered in the group whose number was on the claim for that date; check the group number (EQE guide).
