Z731 – Initial investigation of abnormal cervical cancer screening test or lesion of the lower genital tract
OHIP Psychiatric Code — FEMALE GENITAL SURGICAL PROCEDURES · Schedule of Benefits
Initial investigation of abnormal cervical cancer screening test or lesion of the lower genital tract, including vulva under colposcopic technique with or without biopsy(ies). The fee for Z731 is inclusive of the collection of cervical cancer screening specimen(s) for cytology, endocervical curetting, and HPV testing for cervical cancer screening related indications, if performed.
When to Use
- Use Z731 for the initial colposcopic evaluation of a patient referred due to an abnormal cervical cancer screening result (e.g., ASC-H, HSIL, or persistent LSIL).
- Use Z731 when performing an initial colposcopy for a visible lesion of the lower genital tract, including the vulva, regardless of whether a biopsy is ultimately taken.
Common Pitfalls
- Do not bill an office visit code (e.g., A007) on the same day as Z731, as the colposcopy fee is inclusive of the assessment.
- Avoid billing Z731 in conjunction with Z787 or Z730, as these are mutually exclusive codes for colposcopic procedures.
- Do not bill separately for the collection of cervical cytology, endocervical curettage, or HPV testing, as these are explicitly included in the Z731 fee.
Billing Tips
- Ensure the procedure note clearly documents the colposcopic findings and any biopsies performed to support the Z731 claim during potential audits.
- If the procedure is performed after hours or on weekends, apply the appropriate E409 or E410 premium to the Z731 fee to maximize reimbursement for non-elective cases.
