Clinical Context
A 34-year-old woman presents with persistent pelvic pain and a suspected deep vaginal or pelvic mass on pelvic ultrasonography. After failure of conservative management and inconclusive imaging for adnexal pathology, the gynecologic surgeon schedules a transvaginal exploratory incision to assess the vaginal wall and pelvic cavity. In the operating room under general anesthesia, the provider performs a direct incision of the vaginal wall, inspects the pelvic cavity, obtains visual assessment of adnexa and pelvic organs, and performs targeted sampling or minor procedures (biopsy, drainage of an abscess) as indicated. The clinical workflow includes preoperative consent, perioperative antibiotics as appropriate, sterile vaginal preparation, incision and exploration, intraoperative documentation of findings, specimen labeling for pathology if taken, hemostasis, and postoperative recovery with discharge instructions and pathology follow-up if applicable.
Coding Specifications
| Modifier | Description | When to Use |
|---|
22 | Increased procedural services | Use when the work, time, or intensity substantially exceeds typical for the procedure due to extensive exploration or difficult dissection. |
| 23 | Unusual anesthesia | Use when general anesthesia is required for a procedure usually performed under local/regional anesthesia.
| 26 | Professional component | Use when only the physician professional component is billed separate from technical services (rare for this surgical procedure).
| 50 | Bilateral procedure | Use when exploration/incision is performed bilaterally and payer requires bilateral reporting.
| 52 | Reduced services | Use when the procedure is partially reduced or not completed as planned.
| 53 | Discontinued procedure | Use when the procedure is started but terminated for patient-related or clinical reasons prior to completion.
| 59 | Distinct procedural service | Use to indicate a separate and distinct procedural service when another procedure is performed on the same day that may be bundled.
| 62 | Two surgeons | Use when two surgeons from different specialties perform distinct surgical portions of the procedure.
| 63 | Procedure performed on infants less than 4 kg | Not commonly applicable; include only for applicable neonatal cases.
| 78 | Return to operating room for a related procedure following initial procedure during the postoperative period | Use when reoperation is required for complications related to the initial exploration.
| 80 | Assistant surgeon | Use when a surgical assistant is billed in addition to the primary surgeon.
| 81 | Minimum assistant surgeon | Use when a minimal level assistant is provided per payer rules.
| 82 | Assistant surgeon (when qualified resident not available) | Use when an assistant surgeon is required and no qualified resident is present.
