Cutting out or off, without replacement, all of a body part
Procedure Overview
Resection in the endocrine system means the complete surgical removal of a gland such as the thyroid, a parathyroid gland, an adrenal gland, or the pituitary, without any replacement structure put in its place. It is one of the most frequently performed procedures in endocrine surgery because so many endocrine conditions, from cancer to hormone-secreting tumors to autoimmune overactivity, are best treated by taking the entire gland out.
Common reasons include thyroid cancer or a large multinodular goiter, Graves' disease that has not responded to medication, a parathyroid adenoma causing hyperparathyroidism, an adrenal tumor such as a pheochromocytoma, or a pituitary tumor removed through the skull base. Because these glands regulate metabolism, blood pressure, calcium balance, and stress hormones, patients undergoing resection typically need lifelong hormone replacement or monitoring afterward, which their care team discusses well before surgery.
Anatomy & Axis Detail
Carotid Body, Right
The right carotid body lies at the bifurcation of the right common carotid artery, functioning as a chemoreceptor that monitors arterial oxygen and carbon dioxide levels to help drive ventilation. It is resected primarily to remove a carotid body tumor or paraganglioma, a typically slow-growing but highly vascular mass that can splay the carotid bifurcation and encase branches of the cranial nerves as it enlarges. Surgical planning often includes cross-sectional imaging or angiography to grade tumor size relative to the skull base, since larger Shamblin class lesions carry higher risk of vascular or nerve injury during dissection. The operation proceeds in a subadventitial plane to free the tumor from the carotid vessels while preserving arterial continuity, and documentation of complete gland and tumor removal supports coding as Resection.
Approach: Percutaneous Endoscopic
Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.
Coding & Documentation
The operative report must confirm the entire gland was removed, not a lobe, nodule, or partial gland, since a partial removal is coded as excision instead. When a total thyroidectomy is performed in stages or as completion surgery after a prior partial removal, coders need to check whether any residual tissue remained from the earlier operation and code accordingly. A common mistake is coding bilateral adrenalectomy or parathyroidectomy as a single procedure when each gland is a separate body part value requiring its own code. Coders should also watch for cases where a resection is combined with a separate reconstructive or reconstructive-adjacent step, such as autotransplantation of a parathyroid gland fragment, which requires an additional code.
