Operation Definition
Taking out or off a device from a body part
Procedure Overview
Removal in this family covers taking out a device that was previously placed in or on an endocrine structure - for example a drain left after adrenal or thyroid surgery, a radioactive seed or marker placed near a gland, or a monitoring lead. It applies specifically to hardware and implanted materials, not to the glandular tissue itself.
Patients encounter this procedure when a temporary device has served its purpose and needs to come out, when a device has failed or become infected, or when a permanent device is being planned for replacement. Because endocrine glands are usually not fitted with long-term mechanical implants the way joints or hearts are, Removal in this body system is generally tied to short-term post-surgical devices or localization aids used during treatment.
Anatomy & Axis Detail
Pituitary Gland
The pituitary gland sits within the sella turcica at the skull base and functions as the master regulator of the endocrine system, controlling hormone output from the thyroid, adrenal glands, and gonads through its anterior and posterior lobes. Removal of all or a portion of the gland is most often performed for functioning or nonfunctioning adenomas, Cushing disease, or other mass lesions causing local compression of the optic chiasm or hormonal dysregulation. The approach is typically transsphenoidal, passing through the nasal cavity and sphenoid sinus rather than through an open cranial incision, which affects how the procedure is coded with respect to approach value. Because the gland lies adjacent to the cavernous sinus, carotid arteries, and optic apparatus, documentation should clarify whether the excision is partial or total, as complete removal typically necessitates lifelong hormone replacement therapy.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
Device: Drainage Device
Drainage Device denotes a device such as a tube or catheter left in place to remove fluid, blood, or air from a body part or cavity following a procedure. It is distinguished from Monitoring Device, which senses and records physiologic data rather than evacuating substances from the body.
Coding & Documentation
A coder needs documentation identifying the specific device being taken out and confirming that no new device is being put in during the same operative step - if a device is removed and immediately replaced with a new one, Removal is coded together with an additional Insertion, Replacement, or the combined-value convention specified in the PCS tables. Notes should state the type of device and its original placement.
A common error is coding Removal when a device is actually being adjusted or repositioned rather than taken out entirely, which instead falls under Revision; another is failing to code the separate Insertion when a device is swapped rather than simply removed.
