This service is for a culdotomy, involving an incision into the cul-de-sac for drainage or needle puncture. As indicated by the # prefix, when this procedure is performed in a hospital or Integrated Community Health Services Centre (ICHSC), the costs for premises, equipment, supplies, and personnel are covered by the facility's budget and not billed separately to the patient ().

When to Use

Use S712 for the surgical drainage of a pelvic abscess via the posterior vaginal fornix (culdotomy).
Use S712 for diagnostic needle aspiration of the cul-de-sac when performed as a distinct surgical procedure rather than as part of a larger pelvic surgery.

Common Pitfalls

Do not bill S712 in addition to a more comprehensive procedure like a hysterectomy or oophorectomy, as it is considered an integral component of the primary surgical approach.
Avoid billing S712 as an office procedure; the '#' prefix mandates that it must be performed in a hospital or ICHSC setting to be eligible for the professional fee.
Do not attempt to bill for a surgical assistant (S712B) without prior authorization, as this code is not on the pre-approved list for assistant eligibility.

Billing Tips

If you require a surgical assistant for a complex case, you must submit a letter to a medical consultant justifying the necessity to obtain authorization for the S712B claim.
Ensure the procedure start time is accurately recorded to support the application of after-hours premiums (E409/E410) if the drainage is performed on an urgent, non-elective basis.
