Operation Definition
Taking or letting out fluids and/or gases from a body part
Procedure Overview
Drainage procedures remove fluid or gas from a body part in the female reproductive system, most commonly to relieve pressure or infection from a collection such as a pelvic abscess, an infected fallopian tube, or a fluid-filled ovarian cyst. The fluid may be withdrawn with a needle and syringe, through a small incision that is then left open or packed, or via a catheter placed to allow continued drainage over time.
This type of procedure is typically performed when a collection of pus, blood, or cystic fluid is causing pain, fever, or pressure on nearby structures and needs to be evacuated for the patient to improve. Culdocentesis, in which fluid is aspirated from the pouch behind the uterus to evaluate for internal bleeding or infection, and percutaneous or laparoscopic drainage of a tubo-ovarian abscess are typical examples, and the approach can range from a simple office aspiration to a more involved procedure requiring imaging guidance or surgical access.
Anatomy & Axis Detail
Ovary, Left
Drainage of the left ovary addresses fluid, pus, or blood collections within or around this gonad, most commonly a hemorrhagic or infected ovarian cyst, an abscess, or a hematoma following torsion or rupture. The procedure can be accomplished percutaneously under ultrasound guidance, laparoscopically, or through an open approach, with the choice influenced by the collection's size, the patient's stability, and whether concurrent pelvic pathology needs evaluation. Since the left ovary lies near the sigmoid colon and left ureter, image-guided aspiration is favored when feasible to reduce injury risk. Coders should verify the operative note identifies the ovary as the source of drained fluid rather than an adjacent structure, and note whether a drainage device remained in place after the procedure.
Approach: Percutaneous
Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.
Coding & Documentation
Supporting documentation should describe fluid or gas being taken or let out of a specific body part, along with the method of access - needle aspiration, incision and drainage, or catheter placement - and whether the drainage device was left in place afterward. If a drainage catheter remains after the procedure, the encounter is typically coded with the qualifier indicating a device was left in, and coders need to check the note carefully for that detail since it changes the code selection even though the root operation stays Drainage. A common mistake is coding Drainage when the procedure actually involved removing an entire fluid-filled structure, such as a cyst, along with its wall, which should instead be coded as Excision or Resection of the cyst.
