Operation Definition

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, Left

The left carotid body is a small chemoreceptor organ nestled at the bifurcation of the left common carotid artery, sensing blood oxygen, carbon dioxide, and pH to regulate respiratory drive. Resection is performed chiefly for carotid body tumors, or paragangliomas, which are usually benign but can compress or invade adjacent vascular and cranial nerve structures as they enlarge within the carotid sheath. Because the tumor is intimately associated with the internal and external carotid arteries and the vagus and hypoglossal nerves, dissection requires meticulous subadventitial technique to avoid vascular injury or cranial nerve palsy, and preoperative embolization may be used for larger, hypervascular lesions. Complete excision of the chemoreceptor tissue, not just partial debulking, is what qualifies the procedure as Resection under this body part value.

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.

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.

Commonly Confused With

ExcisionExcision is the closest neighbor and is easy to mix up with resection; excision applies when only part of the gland, such as a single lobe or nodule, is taken out, while resection requires the entire gland.
ExtirpationExtirpation, used for removing an abnormal substance like a stone or clot rather than gland tissue itself, is occasionally confused with resection in adrenal or pancreatic procedures.
DestructionDestruction, which eliminates tissue in place with energy such as radiofrequency ablation rather than cutting it out, is also sometimes conflated with resection when a gland is destroyed rather than physically removed.
