An adrenalectomy is the surgical removal of one (unilateral) or both (bilateral) adrenal glands, either partially or completely. It is most commonly performed to treat adrenal tumors (benign or malignant), hormone-secreting tumors causing Cushing’s syndrome or Conn’s syndrome, pheochromocytoma, or metastatic disease to the adrenal gland. From a medical-coding perspective, adrenalectomy documentation must clarify: Extent (partial vs. complete) Laterality (right, left, bilateral) Approach (open transabdominal, laparoscopic, retroperitoneoscopic, robotic) Indication (tumor type, hormone excess, malignancy, metastasis) Concurrent procedures (nephrectomy, lymphadenectomy)
These distinctions directly affect CPT and ICD-10 code selection. Adrenalectomy is also abbreviated as ADX when referring to the procedure or resulting state. The term derives from Latin ad (near/at) + renalis (relating to the kidneys) + Greek -ektomia (a cutting out).
-ectomy → Greek ektomē, meaning “cutting out” or “excision”
adrenalectomy literally means “cutting out [the gland] near the kidney.”
Note: The Greek equivalent is epinephridio (from epi, “upon,” + nephros, “kidney”), reflecting the same anatomical relationship from a Greek perspective.
Unilateral adrenalectomy: Removal of one adrenal gland; most common; patient typically does not require lifelong steroid replacement
Bilateral adrenalectomy: Removal of both adrenal glands; requires lifelong corticosteroid and mineralocorticoid replacement
Partial adrenalectomy (cortex-sparing): Removes only the tumor while preserving functional adrenal tissue; preferred in bilateral or hereditary disease (e.g., MEN2, VHL)
Surgical Approaches
Open transabdominal: Large incision; used for large or malignant tumors; higher morbidity
Open lumbar or dorsal: Flank or posterior approach; less common
“Bilateral adrenalectomy” (flags need for steroid replacement documentation)
“Specimen to pathology” (confirms tissue removal, not just exploration/biopsy)
“Exploration of adrenal gland with biopsy” (may still be coded 60540/60650 per CPT descriptor)
These help determine approach, extent, laterality, and bundling vs. separate procedure rules.
Coder’s Notes
Approach determines CPT: Open = 60540 or 60545; Laparoscopic = 60650
60540 and 60650 are “separate procedure” codes per CPT — do not bill separately when adrenalectomy is bundled into a more comprehensive procedure (e.g., radical nephrectomy 50545)
CCI bundling: Medicare’s NCCI bundles both 60540 and 60650 with all nephrectomy codes — adrenalectomy is considered inclusive when performed with nephrectomy
If surgeon performs significant additional work (e.g., excising a retroperitoneal mass), append modifier -22 to represent increased procedural service
Laterality modifiers: Use modifier -LT (left side) or -RT (right side) when required by payer; some payers reject modifier -50 for bilateral and require the code billed twice with -LT and -RT
Bilateral adrenalectomy: If both glands removed in same session, check payer rules — use modifier -50 or bill twice with -LT/-RT
For robotic-assisted approach, report 60650 — there is no separate robotic modifier required by most payers, but documentation must describe the robotic technique
Postprocedural adrenocortical hypofunction following bilateral adrenalectomy should be coded as E89.6
