As
@Orthocoderpgu states above, you can never code and bill for something not documented.
IF there is documentation, there are several requirements to using -62.
1) CPT code must allow co-surgeons
2) Each physician provides their own op note specifying which portions they performed. The op notes should specify the other physician was co-surgeon
3) The 2 physicians are different specialties
4) Both surgeons must bill with -62
5) Each surgeon is primary for part of a procedure that is correctly described by one code
Based on the limited information you provided, it does sound more like your physician assisted. Or perhaps they were co-surgeons, but only for a specific procedure.
Here's an example from my world of gynecologic oncology.
Let's say a patient is scheduled for a vulvar biopsy and total hysterectomy with removal of tubes and ovaries.
Ob/gyn does the vulvar biopsy. Then removes an ovary with attached cyst and sends for frozen section while starting to remove the other tube/ovary and uterus/cervix. The frozen section comes back with a malignancy and the ob/gyn calls my doctor in. My doctor completes the hysterectomy and then also does pelvic and para-aortic lymphadenectomy. 58210 is for the radical hysterectomy with tubes and ovaries and lymphadenectomy.
Each physician dictates which portion they performed as primary. The ob/gyn would bill 58210-62 and 56605 for the vulvar biopsy.
Gynonc would bill 58210-62.
Even if the 56605 allowed -62 (it doesn't), it would be wrong for gynonc to bill that since they did not participate in it.
Now, there are plenty of times the ob/gyn might open a patient, then realized there is a high suspicion for malignancy and immediately call in gynonc. In those situations, the gynonc bills primary and the ob/gyn as assist.
