Crystal's MCW Coder Hub🩺 CPT Code 38531 - Biopsy or Excision of Lymph Node(s); Open, Inguinofemoral Node(s)
📋 Code Description
Biopsy or excision of lymph node(s); open, inguinofemoral node(s)
CPT 38531 describes an open surgical biopsy or excision of one or more inguinofemoral lymph nodes. This procedure involves a formal surgical incision — most commonly in the groin — to access, isolate, and either biopsy (sample) or completely excise lymph nodes within the inguinal and/or femoral nodal basins.
This code applies regardless of whether the intent is:
- Diagnostic (biopsy for histopathologic analysis — e.g., lymphoma staging, metastatic disease evaluation)
- Therapeutic (excision of involved nodes — e.g., removal of palpable metastatic deposits)
- Staging (surgical staging for melanoma, vulvar carcinoma, penile carcinoma, anal carcinoma)
The inguinofemoral nodal group is a critical lymphatic drainage basin for the lower extremities, perineum, external genitalia, distal rectum, and anal canal, and is frequently involved in the metastatic spread of malignancies arising from these structures.
⚠️ 38531 applies to open procedures only. Needle-based, ultrasound-guided, or core-needle biopsies of inguinal lymph nodes are reported with fine-needle aspiration or percutaneous biopsy codes and are not captured under 38531.

🧭 Anatomic Overview — Inguinofemoral Lymph Nodes
The inguinofemoral lymph node group encompasses two distinct but anatomically related nodal tiers:
Superficial Inguinal Nodes
- Located in the femoral triangle, within the subcutaneous tissue above the fascia lata
- Arranged in horizontal and vertical groups relative to the inguinal ligament and saphenous vein
- Drain: lower abdominal wall, perineum, scrotum/labia majora, penis/clitoris, distal vagina, distal anal canal, lower extremity superficial tissues
Deep Inguinal (Femoral) Nodes
- Located medial to the femoral vein, below the fascia lata, within the femoral canal
- The most superior deep inguinal node is known as the Node of Cloquet (Rosenmüller), located at the femoral ring
- Drain: deep structures of the lower extremity, glans penis/clitoris, deep perineal structures
📌 In surgical oncology — particularly for melanoma, penile cancer, vulvar cancer, and anal cancer — careful dissection of both the superficial and deep inguinofemoral nodal groups is critical for accurate staging and regional disease control.
🔬 Procedure Details — What the Surgery Involves
A typical open inguinofemoral lymph node biopsy or excision includes:
- Positioning: Patient supine, with slight hip flexion/abduction (frog-leg or modified lithotomy depending on access needs)
- Incision: Oblique or longitudinal groin incision parallel to or below the inguinal ligament, centered over the femoral triangle
- Dissection: Subcutaneous dissection through Scarpa’s fascia; identification of the saphenous vein and femoral vessels
- Node identification and isolation: Careful dissection around targeted nodal tissue while protecting the femoral artery, femoral vein, femoral nerve, and saphenous vein
- Biopsy/Excision: Targeted node sampling (biopsy) or formal excision of all nodal tissue within the dissection field
- Hemostasis and closure: Ligation of lymphatic channels where visible; layered wound closure; drain placement (common for larger dissections to prevent lymphocele)
⚠️ 38531 vs. 38740/38745: 38531 describes biopsy or limited excision of inguinofemoral nodes. A radical or complete inguinofemoral lymphadenectomy (used in definitive cancer surgery) is reported with 38740 (superficial) or 38745 (superficial + deep). The extent of the dissection documented in the operative report determines which code applies.
💊 wRVU & Reimbursement Summary
| Component | Value |
|---|---|
| Work RVU (wRVU) | 5.32 |
| Global Period | 90 days |
| Pre-Operative Period | 1 day |
| Post-Operative Care | Included (routine 90-day global follow-up) |
| Assistant at Surgery | ✅ Payable — verify individual payer |
| Co-Surgeon | May be applicable — payer-specific |
| Bilateral Procedure | See modifier 50 guidance below |
| Facility vs. Non-Facility RVU | Higher reimbursement in non-facility; typically performed in facility/OR setting |
💡 The wRVU of 5.32 reflects the significant operative complexity of the inguinofemoral region — the dense proximity of the femoral artery, vein, and nerve combined with rich lymphatic networks makes this dissection technically demanding and time-intensive compared to more superficial node biopsies such as 38500 (2.60 wRVU).
🔁 Bilateral Considerations
38531 as written describes a unilateral procedure. When performed bilaterally in the same operative session:
| Scenario | Correct Reporting |
|---|---|
| Bilateral inguinofemoral excision | 38531 - 50 (bilateral procedure modifier) |
| Two separate surgeons performing bilateral | 38531 - 62 (co-surgeon) on each claim |
| Right side only | 38531 - RT |
| Left side only | 38531 - LT |
📌 Some payers require separate line items with RT and LT rather than modifier 50. Always verify payer-specific bilateral billing rules.
🔁 Common Modifiers Used With 38531
| Modifier | Description & Use |
|---|---|
| -50 | Bilateral procedure — bilateral inguinofemoral node excision in the same session |
| -51 | Multiple procedures — when 38531 is performed with another surgical procedure in the same session |
| -59 | Distinct procedural service — when payer incorrectly bundles 38531 with a primary oncologic procedure |
| -XS | Separate structure — NCCI-preferred alternative to -59 in some bundling contexts |
| -RT | Right side |
| -LT | Left side |
| -80 | Assistant surgeon — payable; document medical necessity |
| -81 | Minimum assistant surgeon — less common; payer-specific |
| -62 | Co-surgeon — when two surgeons of different specialties each perform distinct portions of the procedure |
| -52 | Reduced services — rarely applicable; if procedure is significantly less than described |
| -58 | Staged/related procedure within global period — when inguinofemoral dissection follows a prior sentinel node biopsy or primary excision |
| -79 | Unrelated procedure during postoperative period of prior surgery |
| -78 | Return to OR for complication during global period (e.g., evacuation of lymphocele requiring reoperation) |
✅ Includes
- Open surgical incision and approach to the inguinofemoral nodal basin
- Dissection and isolation of inguinal and/or femoral lymph nodes
- Biopsy (partial or excisional) of one or more nodes
- Complete excision of targeted nodes (limited, not radical)
- Intraoperative hemostasis (electrocautery, ligation)
- Ligation of visible lymphatic channels encountered during dissection
- Wound irrigation
- Layered wound closure
- Placement of a closed suction drain (when performed as part of the procedure)
- Local/regional anesthesia administered by the operating surgeon (if applicable)
- Routine pathology submission of excised tissue (professional fee only; technical component billed by pathology separately)
❌ Excludes / Do Not Report Separately
| Excluded Code / Scenario | Reasoning / Correct Action |
|---|---|
| 38740 / 38745 (Radical inguinofemoral lymphadenectomy) | When a complete superficial ± deep inguinofemoral lymphadenectomy is performed, 38740 or 38745 apply — not 38531 |
| 38792 (Radioactive tracer, sentinel node) | Injection of radioactive tracer for sentinel node mapping is reported separately if performed as a distinct service; however, if done in the same session as 38531, NCCI edits must be reviewed |
| 38900 (Intraoperative lymphatic mapping) | Intraoperative lymphatic mapping/sentinel node with blue dye or gamma probe — verify if separately reportable based on payer and NCCI |
| 38500 (Superficial open lymph node biopsy) | Do not substitute 38500 for inguinofemoral nodes — 38531 is the site-specific code |
| Fine-needle aspiration (10021 / 10004-10012) | FNA of inguinal nodes is not an open procedure; use appropriate FNA/core biopsy codes |
| Ultrasound-guided biopsy (76942) | Image-guided percutaneous biopsy is not an open procedure — not reportable as 38531 |
| Sentinel lymph node biopsy, inguinal (38525 / 38531 with 58) | Distinguish between sentinel node biopsy (often coded with 38500 or 38531 depending on documentation) and completion lymphadenectomy |
| Pathology / frozen section | Separately billed by pathology under appropriate pathology CPT codes; not bundled into 38531 |

🏥 MS-DRG Considerations (Inpatient Setting)
⚠️ In the inpatient hospital setting, CPT codes are not used for procedure reporting. ICD-10-PCS codes drive DRG assignment. However, understanding the DRG landscape for inguinofemoral lymph node procedures is essential for inpatient coders.
ICD-10-PCS Equivalent Logic for Inguinofemoral Lymph Node Excision
| PCS Character | Value |
|---|---|
| Section | 0 - Medical and Surgical |
| Body System | 7 - Lymphatic and Hemic Systems |
| Root Operation | B - Excision (partial removal) or T - Resection (complete removal) |
| Body Part | H - Lymphatic, Right Inguinal; J - Lymphatic, Left Inguinal |
| Approach | 0 - Open |
| Device | Z - No Device |
| Qualifier | X - Diagnostic (biopsy) or Z - No Qualifier (therapeutic excision) |
Example PCS Codes:
07BH0ZX— Excision of Right Inguinal Lymphatic, Open, Diagnostic07BJ0ZX— Excision of Left Inguinal Lymphatic, Open, Diagnostic07TH0ZZ— Resection of Right Inguinal Lymphatic, Open07TJ0ZZ— Resection of Left Inguinal Lymphatic, Open

📌 Coding Specificity Guidance:
- When the primary malignancy is known, code the primary site as the principal diagnosis with C77.4 (or appropriate secondary node code) as an additional diagnosis.
- When inguinofemoral lymph node excision is being performed for initial staging of a known primary, sequence the primary malignancy first.
- When the lymph node pathology is the primary unknown (e.g., lymphoma workup), R59.0 or D47.9 may serve as the principal diagnosis pre-pathology, with the confirmed diagnosis coded after results return (on a subsequent claim if necessary).
💡 Coding Examples
Example 1 — Melanoma Staging, Inguinal Lymph Node Excision
Clinical Scenario:
A 58-year-old male with a previously excised T3b malignant melanoma of the right thigh presents for open excisional biopsy of a clinically suspicious right inguinal lymph node. The surgeon performs an open incision over the right femoral triangle, identifies and excises a 2.8 cm firm lymph node. Frozen section confirms metastatic melanoma.
Correct Coding:
- 38531 - -RT — Open excision, right inguinofemoral lymph node
- C77.4 — Secondary malignant neoplasm of inguinal and lower limb lymph nodes
- C43.71 — Malignant melanoma of right lower limb
✅ 38531 is appropriate for open inguinofemoral node excision regardless of the number of nodes excised within the inguinofemoral basin, as long as it does not constitute a complete radical lymphadenectomy (which would be 38740 or 38745).
Example 2 — Lymphoma Workup, Bilateral Inguinal Lymph Node Biopsy
Clinical Scenario:
A 44-year-old female presents with bilateral inguinal lymphadenopathy, night sweats, and weight loss. CT imaging shows bilateral enlarged inguinal and iliac nodes. The hematologist requests open bilateral inguinofemoral lymph node biopsies for tissue diagnosis. The surgeon excises one node from each groin during the same operative session.
Correct Coding:
- 38531 - -50 — Open biopsy, bilateral inguinofemoral nodes (same session)
- R59.1 — Generalized enlarged lymph nodes (pre-pathology)
- (After pathology confirms lymphoma, update to appropriate C-code on subsequent visits)
✅ Modifier -50 applied for bilateral procedure performed in the same operative session. Some payers require 38531 - -RT on one line and 38531 - -LT on a second line instead of -50 — verify by payer.
Example 3 — Vulvar Cancer Staging
Clinical Scenario:
A 67-year-old female with FIGO Stage IB squamous cell carcinoma of the vulva undergoes bilateral inguinofemoral lymph node dissection as part of staging. The gynecologic oncologist performs an open bilateral dissection, removing multiple nodes from each inguinofemoral basin for pathologic staging.
Correct Coding:
- 38531 - -50 — Bilateral open inguinofemoral lymph node excision
- C51.9 — Malignant neoplasm of vulva, unspecified
- (If the dissection is extensive and constitutes a complete inguinofemoral lymphadenectomy, evaluate 38740 - -50 or 38745 - -50 instead)
⚠️ Critical distinction: If the operative note describes a complete inguinofemoral lymphadenectomy (all superficial ± deep femoral nodes removed en bloc as part of definitive cancer surgery), 38740 or 38745 is more appropriate than 38531. Review the operative note carefully for the scope of dissection.
Example 4 — Inguinal Node Biopsy Combined With Primary Excision of Skin Lesion (Same Session)
Clinical Scenario:
A 52-year-old male undergoes wide local re-excision of a melanoma on the left thigh (11606) and an open biopsy of two suspicious left inguinal lymph nodes during the same operative session.
Correct Coding:
- 38531 - -LT - -51 — Open inguinofemoral lymph node excision, left, multiple procedures
- 11606 — Excision, malignant lesion, trunk/extremities; over 4.0 cm
- C43.72 — Malignant melanoma of left lower limb
- C77.4 — Secondary malignant neoplasm of inguinal and lower limb lymph nodes
✅ -51 applied to 38531 as the secondary procedure when billed with 11606 (primary). Some payers may reverse the order of value; apply -51 to the lower-valued procedure.
Example 5 — Sentinel Node Biopsy Followed by Completion Lymphadenectomy (Staged Procedure)
Clinical Scenario:
A patient underwent sentinel lymph node biopsy of the right groin 3 weeks ago for a right thigh melanoma. Pathology returned positive. The patient now returns for a completion right inguinofemoral lymph node dissection.
Correct Coding:
- 38531 - -RT - -58 — Open inguinofemoral node excision, right; staged/related procedure within global period of prior sentinel biopsy
- C77.4 — Secondary malignant neoplasm of inguinal and lower limb lymph nodes
- C43.71 — Malignant melanoma, right lower limb
✅ Modifier -58 documents that this procedure is a planned staged procedure related to the prior sentinel node biopsy — it avoids the denial that might result from the active global period of the first procedure while correctly reporting a distinct, separately planned surgical intervention.
Example 6 — Inpatient Lymphoma Staging (ICD-10-PCS)
Clinical Scenario:
A 39-year-old admitted for workup of a mediastinal mass with bilateral inguinal lymphadenopathy undergoes an open right inguinal lymph node excisional biopsy for tissue diagnosis during the inpatient stay. Pathology confirms Hodgkin lymphoma.
Inpatient ICD-10-PCS Procedure Code:
07BH0ZX— Excision of Right Inguinal Lymphatic, Open Approach, Diagnostic
ICD-10-CM Diagnoses:
- C81.98 — Hodgkin lymphoma, unspecified, lymph nodes of multiple sites (principal dx post-confirmation)
- R59.1 — Generalized enlarged lymph nodes (may be principal at time of admission if lymphoma not yet confirmed)
MS-DRG: 820-822 (Lymphoma & Leukemia w Major O.R. Procedure ± CC/MCC), depending on CC/MCC burden
⚠️ Common Coding Pitfalls
- Using 38500 instead of 38531 for inguinofemoral nodes: 38500 (superficial open biopsy) is a nonspecific code. 38531 is the correct site-specific code for inguinofemoral nodes and should always be used when the documentation specifies this anatomic region.
- Confusing 38531 with 38740/38745: 38531 is for biopsy or limited excision; 38740/38745 are for complete radical inguinofemoral lymphadenectomy. Review the operative note for the scope of dissection — if all nodal tissue is removed en bloc as a definitive cancer operation, the lymphadenectomy codes apply.
- Failing to use bilateral modifier: When both inguinal regions are addressed in the same session, modifier -50 (or -RT/-LT per payer) must be applied. Billing only one unit without a bilateral indicator will result in underpayment.
- Separately billing sentinel node injection when performed same session: Review current NCCI edits carefully before separately reporting 38792 (radioactive tracer injection) or 38900 (intraoperative mapping) when performed in conjunction with 38531.
- Not coding the primary malignancy: When inguinofemoral node excision is performed for staging of a known primary malignancy (melanoma, vulvar cancer, penile cancer, etc.), the primary malignancy must be coded in addition to the nodal diagnosis.
- Using 38531 for percutaneous/ultrasound-guided biopsy: 38531 is open surgery only. Core needle or FNA approaches require separate codes (10004, 10005, 10021, etc.).
- Ignoring ICD-10-PCS for inpatient claims: In the inpatient setting, ICD-10-PCS root operations (Excision vs. Resection), body part values, and approach characters drive DRG assignment. CPT is irrelevant for inpatient hospital billing.
- Incorrect 7th character on trauma/secondary diagnoses: Ensure all applicable injury or encounter-based 7th characters are properly assigned on supporting diagnosis codes.
