Operation Definition
Cutting out or off, without replacement, a portion of a body part
Procedure Overview
Excision procedures in the female reproductive system involve cutting out a portion of an organ or structure - such as a wedge of ovarian tissue, part of a fallopian tube, a myomectomy removing a fibroid from the uterine wall, or a partial vulvectomy - while leaving the remainder of that body part in place. These procedures are used both to treat disease and to obtain tissue for diagnosis, so the same root operation covers everything from a small cervical biopsy to removal of an ectopic pregnancy mass confined to a tube.
Patients encounter excision most often for suspicious lesions that need pathological evaluation, benign growths like fibroids or ovarian cysts that are causing pain or bleeding, or endometriosis implants that need to be removed without sacrificing the organ they're attached to. Because only part of the structure is taken, the remaining organ typically continues to function, which distinguishes the intent behind excision from operations that remove an entire body part.
The surgical approach varies widely - some excisions are done through a hysteroscope or laparoscope with small ports, others through an open abdominal incision - but the defining feature is always partial removal without replacing the tissue taken out.
Anatomy & Axis Detail
Ovaries, Bilateral
Bilateral removal of the ovaries eliminates the primary source of estrogen, progesterone, and oocyte production in the body, and is performed for conditions such as bilateral malignancy, extensive endometriosis, or as a risk-reducing measure in patients carrying BRCA or other hereditary mutations that markedly elevate ovarian cancer risk. Because both adnexal structures are addressed in a single operative episode, this procedure induces surgical menopause immediately if performed on a premenopausal patient, prompting discussion of hormone replacement therapy and its associated cardiovascular and bone health implications. The bilateral approach is frequently paired with salpingectomy given evidence that many high-grade serous cancers originate in the fallopian tube fimbriae, and surgeons must carefully dissect the infundibulopelvic ligaments on both sides while protecting the ureters, which course close to this vascular pedicle bilaterally.
Approach: Via Natural or Artificial Opening
Via Natural or Artificial Opening means the instrument reaches the target site by passing through an existing body orifice, such as the mouth or urethra, or a surgically created opening like a stoma, without additional incision or scope guidance. It is distinguished from the Endoscopic variant by the absence of a visualizing scope, and from External by actually traversing into the body through that opening.
Coding & Documentation
A coder should look for operative language describing removal of "a portion," "a segment," or a discrete lesion, mass, or margin of tissue, with the rest of the organ left intact. Pathology reports confirming a specimen of a specific size or the surgeon's note describing wedge resection, partial salpingectomy, or myomectomy all support Excision. The approach value (open, percutaneous endoscopic, or via natural orifice) should match the documented technique precisely, since laparoscopic and open myomectomies carry different codes despite the same root operation.
The most common assignment error is confusing Excision with Resection when an entire organ, tube, or ovary is actually removed - documentation stating "total" or "complete" removal points to Resection instead. Coders also sometimes default to Excision for biopsies without confirming the qualifier value that identifies a diagnostic procedure, and miss cases where multiple structures were excised in the same operative session, each requiring a separate code.
