Understand the Difference Between Cystectomy and Cyst Removal

In the world of medical procedures, terms can often be confusing, especially when they sound similar but have very different meanings. One such example is the distinction between the terms cystectomy and cyst removal. While both may suggest the removal of a cyst, in clinical terminology, they refer to distinct procedures involving different organs and techniques. Understanding this difference is crucial for accurate communication, documentation, and medical coding.

Was It Truly A "Cystectomy" If The Cyst Was Para-Ovarian, Not Ovarian?

The physician documented a "cystectomy" with excision and removal of the cyst in toto, referring to a large para-ovarian cyst found intraoperatively during an appendectomy. However, based on the operative note details, the terminology used might be somewhat misleading.

The findings clearly describe a para-ovarian cyst, not an ovarian cyst. The right ovary itself appeared normal aside from a small cyst, and the para-ovarian cyst was distinctly separate, lying adjacent to the ovary and stretching the fallopian tube. The operative technique involved the excision of the para-ovarian cyst from the right adnexa using LigaSure, with careful aspiration and removal via the end pouch.

Summary of Operative Findings

• A large paraovarian cyst measuring approximately 10 cm was identified on the right side.
• The right fallopian tube appeared tortuous and was stretched across the entire length of the cyst.
• The fallopian tube showed multiple areas of pressure-related atrophy.
• The right ovary was found to be grossly normal, except for a small incidental cyst.
• The uterus, left ovary, and left fallopian tube were all normal in appearance.

Procedure Description

• The patient was initially undergoing an appendectomy under general anesthesia.
• Upon discovering the cyst intraoperatively, a gynecologic consultation was requested.
• After obtaining informed consent, the para-ovarian cyst was:
  • Grasped laparoscopically
  • Excised using a blunt-tipped LigaSure device
  • Aspirated and placed in an endo pouch
  • Removed intact through the 12 mm port
• There was no spillage of cystic contents, and hemostasis was achieved.
• Cyst fluid was sent for cytology; the cyst wall was submitted as a specimen.

Cystectomy Refers To - Key Terminology Clarification

The term "cystectomy" typically refers to the removal of a cyst from the ovary or bladder, depending on context. Since the cyst was not arising from the ovary but relatively adjacent to it (para-ovarian), a more precise and accurate description of the procedure would be "para-ovarian cyst excision" rather than simply "cystectomy," which may imply an ovarian origin.

Thus, while the cyst was removed in toto without rupture, and the documentation supports that a cyst was indeed excised, the specific labeling of the procedure as a 'cystectomy' may not fully align with standard surgical terminology, considering the para-ovarian location.

Answer: Evaluation of the Term "Cystectomy" and Appropriate CPT Coding

First, a clarification on terminology: in standard medical usage, the term "cystectomy" refers to the surgical removal of the urinary bladder, either wholly or partially. Although some clinicians may use "cystectomy" informally to describe the removal of various types of cysts, this is not the correct or accepted usage in clinical documentation or medical coding.

Clinical Context and Nature of the Procedure

According to the operative note, a para-ovarian cyst was discovered during a laparoscopic appendectomy. A consulting surgeon was called in intraoperatively to assess and remove the cyst. The cyst was excised laparoscopically without rupture and later aspirated to facilitate removal through an existing port. It is essential to note that the aspiration step does not impact the procedure code selection, as coding guidelines instruct providers to report the most definitive aspect of the surgery, which in this case is the excision.

Why "Cystectomy" Is Inaccurate in This Context?

The cyst in question was para-ovarian, meaning it arose from tissue near the ovary or fallopian tube but not from within the ovary itself. Since "cystectomy" is generally reserved for bladder removal in medical terminology, and the CPT 51xxx series applies specifically to bladder procedures, the use of this term and any related codes would be incorrect in this scenario.

Correct Code Selection and Modifier Use

The appropriate CPT code for this procedure is 58662, which describes a laparoscopic surgical procedure involving excision or fulguration of lesions of the ovary, pelvic viscera, or peritoneal surface. Although the cyst was para-ovarian, it still qualifies under this code as part of the pelvic viscera and peritoneal region.

However, since the consulting surgeon was involved only in the intraoperative portion of the procedure and did not perform the initial port placement or the final closure, it is necessary to report the service with modifier 52 (Reduced Services). This accurately reflects the limited extent of the physician's participation.

Winding Up

While the term "cystectomy" was used in the operative report, it does not correctly represent the procedure performed. The cyst was not of bladder origin, and the surgery involved laparoscopic excision of a pelvic lesion. The correct reporting for this procedure is 58662 with modifier 52, indicating laparoscopic excision of a pelvic lesion with reduced services.

Ensure Accurate Surgical Coding with BillingFreedom’s Expert Support

Accurate medical coding is essential not only for compliance but also for ensuring timely and appropriate reimbursement. Surgical procedures, particularly those involving unexpected intraoperative findings such as para-ovarian cysts, can be challenging to document and code correctly. 

For instance, using the term “cystectomy” for the removal of a para-ovarian cyst may seem appropriate clinically, but is inaccurate in coding terms. In such cases, identifying the correct CPT code, like 58662 with modifier 52 for laparoscopic excision of pelvic lesions, is crucial for proper claim submission.
