🫁 CPT 60540 — Adrenalectomy, Partial or Complete, or Exploration of Adrenal Gland With or Without Biopsy, Transabdominal, Lumbar or Dorsal (Separate Procedure)
Quick Reference
wRVU: 20.28 | Global Period: 090 | Assistant Payable: Yes | Bilateral Indicator: 2 The bilateral indicator of 2 means that if the procedure is reported for both sides (bilateral adrenalectomy), you report the code twice — once with modifier -LT and once with modifier -RT — or once with modifier -50 depending on payer policy. Do NOT assume automatic 150% payment; payers vary in their bilateral payment methodology. The 90-day global period includes all related E/M visits, follow-up care, and minor procedures within that window. An assistant surgeon is payable (indicator 2 confirms this) when clearly documented as medically necessary given the complexity of retroperitoneal dissection.
📋 Clinical Description
CPT 60540 describes an open surgical procedure involving partial or complete removal of one or both adrenal glands, or surgical exploration of the adrenal gland with or without obtaining a biopsy specimen, performed via a transabdominal, lumbar, or dorsal open approach.1 This code is specifically designated as a “separate procedure,” meaning it is bundled into more comprehensive procedures when performed as part of a larger operation — most notably, it is included within all radical and simple nephrectomy codes per NCCI edits and should not be billed separately when an adrenalectomy is performed concurrently with nephrectomy.2
The adrenal glands sit atop both kidneys in the retroperitoneum, making surgical access technically demanding regardless of approach.1 The transabdominal approach offers the widest exposure and is most commonly used for large tumors or malignancies, while the lumbar or dorsal retroperitoneal approach is preferred when a more targeted posterior exposure is appropriate.1 This code explicitly covers open techniques only — laparoscopic adrenalectomy is reported with 60650, and when an open adrenalectomy is combined with excision of an adjacent retroperitoneal tumor, the more specific code 60545 should be used instead.2
This procedure may be performed in the following clinical contexts:
- Adrenal cortical adenoma causing Cushing syndrome — The patient presents with hypercortisolism, and imaging confirms a cortical mass; open adrenalectomy is pursued when the lesion is large (>6 cm), has radiologic features suspicious for malignancy, or when laparoscopic approach is contraindicated.
- Adrenal pheochromocytoma — A catecholamine-secreting tumor of the adrenal medulla requiring careful periods operative alpha-blockade; open approach is commonly chosen for large, locally invasive, or bilateral pheochromocytomas where laparoscopy poses unacceptable hemodynamic risk.
- Primary hyperaldosteronism (Conn syndrome) — Lateralization confirmed by adrenal venous sampling leading to open unilateral adrenalectomy when laparoscopic approach is not feasible.
- Adrenocortical carcinoma (ACC) — A rare but aggressive malignancy requiring wide surgical margins; open approach is strongly preferred to prevent tumor spillage and achieve R0 resection.
- Diagnostic exploration with biopsy — When imaging is inconclusive and tissue diagnosis is required to differentiate between metastatic disease, primary adrenal malignancy, or benign adenoma, open exploration with biopsy under CPT 60540 is appropriate.
🔬 Anatomical & Procedural Considerations
| Variant | Mechanism | Key Notes |
|---|---|---|
| Transabdominal Approach | The abdomen is entered via midline or subcostal incision, providing wide bilateral exposure and visualization of both adrenal glands, surrounding vasculature, and lymph nodes. The adrenal gland is mobilized by ligating adrenal veins — the right adrenal vein drains directly into the IVC, making it a critical point of hemorrhage risk. This approach is standard for large tumors, bilateral disease, suspected malignancy, or when combined with resection of adjacent structures. | The right adrenal vein is extremely short and fragile, requiring meticulous dissection; inadvertent avulsion can result in catastrophic IVC bleeding. Documentation must clearly state the approach to support code selection. If an adjacent retroperitoneal tumor is also excised, upgrade to 60545. |
| Lumbar Retroperitoneal Approach | A flank incision provides direct retroperitoneal access without entering the peritoneal cavity, reducing bowel manipulation and potentially decreasing postoperative ileus. This approach is typically used for unilateral disease with tumors generally under 6 cm, avoiding the morbidity of a transabdominal laparotomy. | This approach is less commonly used since the widespread adoption of laparoscopic techniques but remains valid for open surgery when the retroperitoneum is the preferred access corridor. Code 60540 covers all three approach variants (transabdominal, lumbar, dorsal) under one descriptor, so approach documentation affects clinical coding notes but does not change the CPT code itself. |
| Dorsal (Posterior) Approach | The patient is placed prone and a paravertebral posterior incision provides access to the adrenal gland from behind, offering limited but direct exposure particularly suited to smaller lesions or reoperative cases. This approach avoids the peritoneum entirely and is associated with less blood loss in carefully selected patients. | Exposure is significantly more limited than the transabdominal approach, making it unsuitable for large or malignant tumors. As with all variants, the procedure is captured by the same CPT 60540 descriptor regardless of posterior vs. flank vs. abdominal entry. Always verify laterality is documented to support modifier application. |
Clinical Pearl
The “separate procedure” designation in the 60540 descriptor is your biggest audit exposure flag. Per NCCI bundling logic, 60540 is included in all nephrectomy codes — open and laparoscopic — and should never be reported alongside 50220, 50225, 50230, 50240, 50545, or 50546.2 If your surgeon performs a radical nephrectomy with adrenalectomy, only report the nephrectomy code. Reserve 60540 for standalone adrenal surgery or adrenalectomy truly independent of a renal procedure. Documentation in the operative report must explicitly support that the adrenalectomy was a distinct, separately indicated procedure if ever billed alongside any renal code using modifier -59.
✅ Procedure Includes
- Preoperative assessment and positioning — All work associated with patient positioning, anesthesia preparation review by the surgeon, and skin prep/draping is bundled into the global package.
- Open surgical access — The incision, fascial dissection, peritoneal entry (if transabdominal), and establishment of the surgical field are included in the code.
- Mobilization and dissection of the adrenal gland — Complete circumferential dissection of the gland from surrounding retroperitoneal fat, isolation of adrenal vasculature, and ligation/division of the adrenal vein(s) are included.
- Partial or complete glandular excision — Whether the surgeon removes only a portion of the gland (cortex-sparing) or the entire gland, both are captured by CPT 60540.
- Biopsy, if obtained — Intraoperative biopsy of adrenal tissue for frozen section or permanent pathology is bundled; do not separately report 20206 or similar biopsy codes.
- Exploration without resection — If the surgeon opens the surgical field and explores the adrenal gland but elects not to resect, that exploratory work is still billable under 60540 per the descriptor language.
- Hemostasis and wound closure — All closure layers, drain placement if used, and hemostatic measures are included in the 90-day global package.
- Routine intraoperative pathology handling — Transfer of specimen to pathology is included; the pathology interpretation itself is billed separately by the pathologist.
❌ Excludes / Do Not Report Together
| Code | Description | Relationship |
|---|---|---|
| 60545 | Adrenalectomy, partial or complete, or exploration of adrenal gland with or without biopsy, transabdominal, lumbar or dorsal (separate procedure); with excision of adjacent retroperitoneal tumor | This is the correct upgrade code when the surgeon also excises an adjacent retroperitoneal mass during the same operative session via open approach. Reporting 60540 and 60545 together for the same side/session would be unbundling — use only 60545 when the retroperitoneal tumor excision is documented. |
| 60650 | Laparoscopy, surgical, with adrenalectomy, partial or complete, or exploration of adrenal gland with or without biopsy, transabdominal, lumbar or dorsal | This is the laparoscopic equivalent. Do not report 60540 and 60650 together for bilateral adrenalectomy performed via different approaches in the same session without strong documentation support and modifier -59; most payers will deny one unit. |
| 50545 | Laparoscopy, surgical; radical nephrectomy (includes removal of Gerota’s fascia and surrounding fatty tissue, removal of regional lymph nodes, and adrenalectomy) | The adrenalectomy is explicitly included in the radical nephrectomy descriptor. Reporting 60540 separately would constitute unbundling and is an NCCI violation. |
| 50220 | Nephrectomy, including partial ureterectomy, any open approach including rib resection | Per NCCI, all simple and radical nephrectomy codes bundle adrenalectomy. This is among the most audited bundling pairs in urology and general surgery. |
Bundling Alert
The NCCI bundles CPT 60540 as a component code with all nephrectomy CPT codes — both open and laparoscopic — because the adrenal gland is routinely removed or at minimum addressed as part of radical renal surgery.2 The 90-day global period for 60540 means any post-op E/M visits, wound checks, or minor procedures related to the adrenalectomy within 90 days are not separately billable without a modifier indicating an unrelated service (modifier -24 for E/M, modifier -79 for unrelated procedures). Reporting 60540 alongside any nephrectomy code — even with modifier -59 — is a red-flag audit trigger and requires an ABN-level review justification from the operative documentation. When in doubt, query the surgeon to confirm the adrenalectomy was separately indicated and performed beyond the scope of a concurrent renal procedure.

Bilateral Billing Rules
Bilateral indicator 2 for CPT 60540 means that if the procedure is performed bilaterally, you should report the code twice — once with modifier -LT and once with modifier -RT — and Medicare will pay 150% of the fee schedule amount (100% for the first, 50% for the second).3 Some commercial payers instead require modifier -50 appended to a single line and pay a negotiated bilateral rate, so always verify individual payer policy before submitting. You cannot append modifier -50 AND report two separate lines for the same bilateral procedure; choose one method per payer. When performing a bilateral adrenalectomy (e.g., for bilateral pheochromocytoma or MEN2A), meticulous documentation of both sides is mandatory to support the bilateral claim and avoid a denial for lack of medical necessity on the second unit.
🏷️ Modifier Reference
| Modifier | Name | When to Apply |
|---|---|---|
| -RT | Right Side | Apply when the adrenalectomy or exploration is performed solely on the right adrenal gland; essential for bilateral indicator tracking and laterality-specific claim adjudication. |
| -LT | Left Side | Apply when the procedure is performed solely on the left adrenal gland; failure to append laterality modifiers on paired organ procedures is a top denial reason. |
| -50 | Bilateral Procedure | Use when both adrenal glands are resected during the same operative session; confirm with individual payer whether -50 or dual-line -LT/-RT billing is preferred, as payment methodology varies. |
| -22 | Increased Procedural Services | Appropriate when the operative complexity significantly exceeds the typical service — e.g., extensive adhesions from prior surgeries, large tumor with vascular involvement, or prolonged operative time well above the norm; requires detailed operative note documentation to support. |
| -25 | Significant, Separately Identifiable E/M | Use on the same-day E/M service when a significant, separately identifiable evaluation and management service is provided on the same date as 60540; the decision for surgery visit should already be captured under the global period rules — review carefully before appending. |
| -51 | Multiple Procedures | Append to secondary procedures reported on the same claim as 60540 when multiple surgeries are performed; the lower-valued procedure receives the reduction. |
| -52 | Reduced Services | Use when the procedure is partially performed — e.g., exploration only without resection was planned but the patient’s condition required stopping earlier than anticipated; must be supported by documentation. |
| -53 | Discontinued Procedure | Apply when the procedure is started but discontinued due to patient safety concerns before the key portion is complete; do not use -52 and -53 interchangeably — -53 is for procedures stopped after initiation, -52 for reduced/incomplete completion. |
| -58 | Staged or Related Procedure | Use during the global period when a related staged procedure was planned prospectively at the time of the original adrenalectomy, such as a planned second-look operation or staged bilateral approach. |
| -78 | Return to OR for Related Procedure | Apply when the patient returns to the OR within the 90-day global period for a complication-related procedure such as post-op hemorrhage or wound dehiscence requiring surgical intervention. |
| -79 | Unrelated Procedure During Global Period | Use when a completely unrelated surgical procedure is performed during the 90-day global period of 60540; the procedure must be genuinely unrelated and well-documented as such. |
| -59 | Distinct Procedural Service | Apply with extreme caution and only when documentation clearly supports that 60540 was a distinct service not included in another procedure on the same date; this is the modifier most scrutinized in NCCI audits involving adrenalectomy codes. |
🩺 Common ICD‑10‑CM Pairings
Primary Diagnosis Group
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| D35.01 | Benign neoplasm of right adrenal gland | No | Most common pairing for unilateral right adrenal adenoma; always code to the specific side — D35.00 (unspecified) is insufficient for surgical claims and will often be flagged in clinical documentation improvement (CDI) review. |
| D35.02 | Benign neoplasm of left adrenal gland | No | Left-sided adenoma variant; same laterality coding rules apply — document the side clearly in the operative report and the pathology report. |
| C74.01 | Malignant neoplasm of cortex of right adrenal gland | Yes — HCC 12 | Adrenocortical carcinoma (ACC) is an HCC-mapped diagnosis affecting risk adjustment; ensure the malignant nature is confirmed by pathology and clearly stated in the diagnostic statement by the treating physician. |
| C74.02 | Malignant neoplasm of cortex of left adrenal gland | Yes — HCC 12 | Left-sided ACC; same HCC implications as right-sided; do not code from radiology alone — pathologic confirmation required for the malignant code. |
| E27.0 | Other adrenocortical overactivity | No | Used for Cushing syndrome due to adrenal hyperfunction or adenoma when the adrenal gland itself is the source (adrenal-dependent Cushing); differentiate from pituitary-dependent Cushing (E24.0) which would drive a different surgical approach entirely. |
Secondary Group
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| D44.10 | Neoplasm of uncertain behavior of unspecified adrenal gland | No | Use when the preoperative histologic character is indeterminate and the mass is being removed for diagnostic/therapeutic purposes; update to a specific benign or malignant code post-pathology when possible. |
| E27.5 | Adrenomedullary hyperfunction | No | Report for pheochromocytoma-associated hyperfunction when the primary diagnosis is medullary origin; may pair with D35.01/D35.02 if the pheochromocytoma is benign on final pathology. |
Etiology / Complication
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| C79.71 | Secondary malignant neoplasm of right adrenal gland | Yes — HCC 12 | Use when the adrenal mass is a metastatic deposit from a primary cancer elsewhere (e.g., lung, kidney, melanoma); code the primary malignancy as well, sequencing per ICD-10-CM guidelines for neoplasm. |
| C79.72 | Secondary malignant neoplasm of left adrenal gland | Yes — HCC 12 | Left-sided adrenal metastasis; same sequencing rules apply — primary malignancy should be the principal diagnosis in most inpatient scenarios unless the adrenal lesion is the focus of the admission. |
Coding Specificity Reminder
Never report D35.00 (benign neoplasm of unspecified adrenal gland) or C74.00 (malignant neoplasm of cortex of unspecified adrenal gland) on a surgical claim — the operative report and/or pathology report will always specify laterality.4 When the diagnosis is a pheochromocytoma, distinguish between benign (D35.0x) and malignant (C74.1x) based on pathology, as these carry different HCC weights and risk adjustment implications. ICD-10-CM coding guidelines for neoplasms require you to verify whether the final pathology report changes the working diagnosis code used at the time of surgery. If the adrenalectomy is performed for a functional syndrome (e.g., Conn syndrome, Cushing syndrome), code both the syndrome (E26.x, E24.x, E27.0) and the underlying adrenal lesion when both are documented.
🏥 MS‑DRG Considerations
CPT 60540 maps to MDC 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders) and serves as an operative trigger for DRG 614 (Adrenal and Pituitary Procedures with CC/MCC) or DRG 615 (Adrenal and Pituitary Procedures without CC/MCC) under ICD-10-PCS MS-DRG v43.0.5 The ICD-10-PCS equivalent procedures — most commonly 0GT30ZZ (Resection of Right Adrenal Gland, Open Approach) or 0GT20ZZ (Resection of Left Adrenal Gland, Open Approach) — are the actual OR procedure codes that trigger DRG assignment in the inpatient setting, not the CPT code directly. As an inpatient profee coder, you’ll note that the DRG assignment is driven by the facility’s ICD-10-PCS coding, but awareness of the DRG grouping impacts documentation requirements for CC/MCC capture — secondary diagnoses like postoperative hypotension, adrenal insufficiency (E27.1), hemorrhage, or the malignant diagnosis HCC codes can shift the case from DRG 615 to the higher-paying DRG 614, making thorough physician query and CDI review critical on these cases. Bilateral adrenalectomy documented with both ICD-10-PCS resection codes will remain in the same DRG pair but may reflect higher complexity for quality metrics purposes.
🔧 ICD‑10‑PCS Equivalents
| PCS Code | Full Description | Modality |
|---|---|---|
| 0GT30ZZ | Resection of Right Adrenal Gland, Open Approach | Open Resection |
| 0GT20ZZ | Resection of Left Adrenal Gland, Open Approach | Open Resection |
| 0GB30ZZ | Excision of Right Adrenal Gland, Open Approach | Open Excision (partial) |
| 0GB20ZZ | Excision of Left Adrenal Gland, Open Approach | Open Excision (partial) |
| 0GT40ZZ | Resection of Bilateral Adrenal Glands, Open Approach | Open Resection — Bilateral |
| 0GB40ZZ | Excision of Bilateral Adrenal Glands, Open Approach | Open Excision (partial) — Bilateral |
PCS Character Analysis — Example: 0GT30ZZ (Resection of Right Adrenal Gland, Open Approach)
| Position | Character | Value | Definition |
|---|---|---|---|
| 1 | Section | 0 | Medical and Surgical — the broadest ICD-10-PCS section covering operative procedures performed on the body. |
| 2 | Body System | G | Endocrine System — captures all glandular structures including adrenal, pituitary, pineal, thyroid, and parathyroid glands. |
| 3 | Root Operation | T | Resection — cutting out or off, without replacement, ALL of a body part; use T (Resection) for complete adrenalectomy and B (Excision) for partial adrenalectomy. |
| 4 | Body Part | 3 | Right Adrenal Gland — laterality is encoded directly into the body part character; value 2 = Left Adrenal Gland, value 4 = Bilateral Adrenal Glands. |
| 5 | Approach | 0 | Open — cutting through the skin and underlying tissue to expose the operative site; this distinguishes from percutaneous endoscopic (4), which would reflect laparoscopic technique. |
| 6 | Device | Z | No Device — no prosthetic, implant, or drainage device is left in place following the procedure. |
| 7 | Qualifier | Z | No Qualifier — no additional specification such as diagnostic (X) applies; note that 0GB30ZX would indicate an open diagnostic biopsy of the right adrenal gland. |
Root Operation Comparison
- Resection (T) vs. Excision (B): Use Resection (0GT30ZZ) when the entire adrenal gland is removed; use Excision (0GB30ZZ) when only a portion is removed (cortex-sparing adrenalectomy). This distinction is critical for DRG and quality reporting accuracy — miscoding a partial resection as a full resection is an ICD-10-PCS specificity error.
- Diagnostic Qualifier (X): When biopsy only is performed without resection or excision, the qualifier character 7 changes to X (Diagnostic), giving you 0GB30ZX for a right-sided open diagnostic biopsy; CPT 60540 covers this scenario as well since its descriptor includes “with or without biopsy.”
- Bilateral code (4): When both adrenal glands are fully resected, use 0GT40ZZ rather than reporting two separate unilateral PCS codes; ICD-10-PCS guidelines generally prefer the bilateral body part value when both sides are addressed via the same root operation and approach.
📝 Coding Examples
Example 1
Clinical Scenario: A 48-year-old female with a history of hypertension and biochemically confirmed primary hyperaldosteronism (elevated aldosterone-to-renin ratio, lateralized left on adrenal venous sampling) is admitted to the hospital. The attending endocrine surgeon performs an open left adrenalectomy via a transabdominal approach. The operative report documents complete excision of the left adrenal gland with identification and ligation of the left adrenal vein. There is no mention of any renal procedure or adjacent retroperitoneal mass resection. Pathology returns a cortical adenoma consistent with Conn syndrome. The patient is discharged on POD 3.
| Field | Code | Rationale |
|---|---|---|
| CPT | 60540-LT | Open left adrenalectomy, transabdominal approach; modifier -LT applied for laterality on this paired organ procedure. |
| PDx | E26.01 | Primary hyperaldosteronism due to adenoma of adrenal gland — this is the condition driving the surgical admission and is the principal diagnosis. |
| SDx | D35.02 | Benign neoplasm of left adrenal gland — codes the adenoma itself as a secondary diagnosis to provide full diagnostic picture; sequence after the functional disorder. |
Note
Example 2
Clinical Scenario: A 62-year-old male with a 7.2 cm right adrenal mass and imaging features highly suspicious for adrenocortical carcinoma is admitted for open right adrenalectomy. Intraoperatively, the surgeon notes local invasion and elects to also excise an adjacent retroperitoneal lymph node mass. The operative note clearly documents separate resection of the retroperitoneal tumor in addition to complete right adrenalectomy. The surgeon spends significantly longer than the typical procedure time due to vascular involvement and extensive dissection.
| Field | Code | Rationale |
|---|---|---|
| CPT 1 | 60545-RT-22 | Adrenalectomy with excision of adjacent retroperitoneal tumor, right side; modifier -22 for significantly increased procedural complexity due to local invasion and extended operative time — must attach operative note documentation to support -22. |
| PDx | C74.01 | Malignant neoplasm of cortex of right adrenal gland — adrenocortical carcinoma confirmed; HCC-mapped diagnosis, critical for risk adjustment. |
Warning
Do NOT report both 60540 and 60545 for this encounter — when a retroperitoneal tumor is also excised, 60545 is the correct and only adrenal code to report; bundling both would constitute unbundling. The -22 modifier should be used judiciously and only when the increased complexity is explicitly and thoroughly documented in the operative report, as payers frequently request records for -22 claims.
Example 3
Clinical Scenario: A 35-year-old female with MEN2A and bilateral pheochromocytomas is admitted for planned staged bilateral adrenalectomy. During this admission, an open right adrenalectomy is performed. The left side is planned for a separate future admission per surgeon documentation in the operative note. Pre-op alpha-blockade with phenoxybenzamine is documented. The procedure is completed without complication.
| Field | Code | Rationale |
|---|---|---|
| CPT | 60540-RT-58 | Open right adrenalectomy; modifier -58 indicates this is a staged procedure with the contralateral adrenalectomy planned and documented prospectively at time of surgery. |
| PDx | D35.01 | Benign neoplasm of right adrenal gland — pheochromocytoma confirmed benign on pathology; if malignant, use C74.11. |
| SDx | Z87.39 | Personal history of other endocrine, nutritional and metabolic diseases — supports MEN2A context in the record. |
Global Period Reminder
The 90-day global period for CPT 60540 begins with the right-sided adrenalectomy. When the patient returns for the left-sided adrenalectomy (60540-LT), modifier -58 must be appended to bypass the global period restriction, as the staged nature was prospectively planned and documented. Failure to use -58 on the second admission will result in a global period denial. The treating physician’s documentation from the original operative note establishing the staged plan is your audit-proof support for the -58.
⚠️ Common Coding Pitfalls
-
Pitfall 1 — Billing 60540 with nephrectomy codes: This is the #1 NCCI violation associated with adrenalectomy coding. The adrenalectomy is bundled into all nephrectomy procedures — open and laparoscopic — and reporting 60540 separately, even with modifier -59, will generate an NCCI edit denial and potentially a post-payment audit if a pattern is detected. Review the operative report to confirm the adrenalectomy was a truly separate, independently indicated procedure before reporting both codes.
-
Pitfall 2 — Using 60540 for laparoscopic approach: CPT 60540 is strictly for open adrenalectomy. Laparoscopic adrenalectomy must be reported with 60650. If the operative report documents a lap-converted-to-open procedure, report only 60540 for the open portion actually performed, and consider modifier -22 if the conversion significantly extended the procedure.
-
Pitfall 3 — Failing to upgrade to 60545 when a retroperitoneal tumor is also excised: Reporting 60540 when 60545 is appropriate leaves reimbursement on the table and creates an accuracy error. Always read the full operative report — not just the pre-op diagnosis — to identify whether adjacent tumor excision was performed before selecting between these sibling codes.
-
Pitfall 4 — Ignoring laterality modifiers: Submitting 60540 without -LT or -RT on a paired organ claim will cause claim processing issues with many payers and is insufficient for medical necessity documentation. Always apply -LT or -RT, and for bilateral cases, verify payer-specific policy for -50 vs. dual-line billing before submission.
-
Pitfall 5 — Coding malignancy without pathologic confirmation: Do not assign C74.0x (malignant neoplasm of adrenal cortex) based solely on imaging or clinical suspicion. ICD-10-CM guidelines require pathologic confirmation for a malignant diagnosis code; use D44.10 (neoplasm of uncertain behavior) until final pathology returns if the case is ambiguous at time of coding.
-
Pitfall 6 — Missing the global period on staged procedures: When a bilateral adrenalectomy is staged across two admissions, the second procedure falls within the 90-day global period of the first. Forgetting to append modifier -58 on the second 60540 claim will result in a global period bundling denial that must then be resubmitted with the correct modifier, creating additional AR days and compliance risk.
