π©Ί CPT Code 55866 - Laparoscopy, Surgical Prostatectomy, Radical, Retropubic, Including Nerve Sparing; Includes Robotic Assistance When Performed
π Code Description
Full Official Description: Laparoscopy, surgical prostatectomy, radical, retropubic, including nerve sparing, includes robotic assistance when performed
CPT 55866 describes a laparoscopic radical prostatectomy (LRP) performed via a retropubic approach, with or without nerve-sparing technique, and inclusive of robotic-assisted technology when utilized. This is the correct CPT code for the widely performed robotic-assisted laparoscopic prostatectomy (RALP) β most commonly performed using the da Vinci Surgical System β and encompasses the entire surgical procedure including all components of the radical prostatectomy regardless of whether nerve sparing is performed on one or both sides.
The procedure involves:
- Laparoscopic or robotic port placement (typically 5-6 ports for robotic approach)
- Development of the space of Retzius (retropubic space) or alternatively a transperitoneal approach to the prostate
- Bladder neck dissection and separation from the prostate base
- Seminal vesicle and vas deferens dissection and excision
- Nerve-sparing dissection along the neurovascular bundles (NVBs) when indicated and oncologically appropriate β unilateral or bilateral
- Apical dissection and division of the urethra
- Complete excision of the prostate gland with attached seminal vesicles
- Vesicourethral anastomosis (bladder neck to urethral stump reconstruction)
- Specimen extraction via an extended port site or Pfannenstiel incision
- Pelvic drain placement when indicated
β οΈ Critical Coding Point: 55866 includes robotic assistance within the code descriptor. There is no separate CPT code for robotic assistance (e.g., S2900 is a HCPCS code used by some payers and facilities but is not universally accepted and is generally not separately reimbursed by Medicare). The robotic platform is bundled into 55866 by AMA definition.
π° Work RVUs & Payment

90-Day Global Period: All related services β including standard postoperative visits, catheter management, and routine complications β are bundled into the global surgical package for 90 days post-operatively. Separately billable services within the global include unrelated conditions, return to the OR, and staged procedures.
Assistant at Surgery: 55866 carries an assistant surgeon indicator of 1, meaning Medicare and most commercial payers will reimburse an assistant surgeon at typically 16% of the primary surgeonβs allowable when billed with modifier -80, -81, or -AS (for a PA/NP first assist). Robotic console-side assistance is common and should be clearly documented.
β Whatβs Included (Bundled into 55866)
The following are not separately reportable when performed as part of the same operative session as 55866:
- All laparoscopic port placements and trocar insertions
- Robotic system docking and undocking (da Vinci or equivalent)
- Bladder neck dissection
- Seminal vesicle dissection and removal (bilateral)
- Vas deferens ligation and excision (bilateral)
- Nerve-sparing dissection β unilateral or bilateral (the descriptor states βincluding nerve sparingβ)
- Urethral dissection and division at the apex
- Vesicourethral anastomosis (posterior reconstruction of Rocco stitch and anastomosis)
- Pelvic drain placement (when performed as part of standard closure)
- Foley catheter placement
- Local/regional anesthesia administration by the surgeon (unusual; typically anesthesia bills separately)
- Standard intraoperative blood loss management
- Specimen extraction
π« Excludes / Separately Reportable
| Service | Separately Reportable Code | Notes |
|---|---|---|
| Pelvic lymph node dissection (PLND) | 38571, 38572 | See section below β critical add-on distinction |
| Limited pelvic lymph node biopsy (sentinel or limited) | 38562 | Fewer nodes than full PLND |
| Cystourethroscopy performed for separate diagnostic purpose | 52000 | Append modifier -59 or -XU |
| Urethral dilation at same session (unrelated) | 53600-53665 | Only if distinct separate service |
| Robotic assistance HCPCS code | S2900 | Facility use only; not Medicare-payable; some commercial payers |
| Postoperative complications requiring return to OR | Appropriate surgical code + modifier -78 | Within global period |
| Unrelated E/M during global | Appropriate E/M + modifier -24 | Must be unrelated to surgery |
| Staged procedure during global | Appropriate procedure code + modifier -58 | Planned/staged |
| Conversion to open (if converted mid-case) | 55840, 55845 + modifier -53 on 55866 | Rare; document reason thoroughly |
π΄ Pelvic Lymph Node Dissection β Critical Add-On Consideration
This is one of the most important separately reportable services in radical prostatectomy coding:
| CPT | Description | When to Use |
|---|---|---|
| 38571 | Laparoscopic bilateral pelvic lymphadenectomy, including external iliac, hypogastric, and obturator nodes | Extended/standard bilateral PLND performed laparoscopically at same session as 55866 |
| 38572 | Laparoscopic bilateral pelvic lymphadenectomy + peritoneal evaluation + diaphragm/pelvic washings | If washings and peritoneal evaluation are also performed |
| 38562 | Limited pelvic and para-aortic lymph node sampling | Sentinel or sampling only, not full PLND |
β Billing Tip: 38571 is separately payable with 55866 per CMS and is not bundled under NCCI edits when a true pelvic lymphadenectomy is performed. Documentation must clearly describe the extent of the dissection: the obturator fossa, external iliac, and hypogastric (internal iliac) nodal packets must all be mentioned to support 38571.

π Open vs. Laparoscopic/Robotic Comparison
| Approach | CPT Code | Nerve Sparing Included? | PLND Included? |
|---|---|---|---|
| Open retropubic, no PLND | 55840 | β Yes (descriptor) | β No |
| Open retropubic, node biopsy | 55842 | β Yes | Limited only |
| Open retropubic, full bilateral PLND | 55845 | β Yes | β Yes - bundled |
| Open perineal radical | 55810 | β No | β No |
| Open perineal + node biopsy | 55812 | β No | Limited only |
| Open perineal + full bilateral PLND | 55815 | β No | β Yes - bundled |
| Laparoscopic/Robotic | 55866 | β Yes - bundled | β Separately reportable |
β οΈ Key Distinction: Unlike open codes 55845 and 55815, which bundle bilateral pelvic lymphadenectomy into the code itself, 55866 does NOT include PLND. When PLND is performed laparoscopically alongside 55866, it is separately reported with 38571 or 38572.

π§ Applicable Modifiers
| Modifier | Description | Application to 55866 |
|---|---|---|
| -80 | Assistant Surgeon | Primary assistant surgeon (MD/DO); reimbursed at ~16% of allowable |
| -81 | Minimum Assistant Surgeon | Second assistant with limited participation; less common for RARP |
| -AS | PA/NP/CNS as Assistant Surgeon | Bedside assistant (non-physician); commonly used for robotic bedside assistant |
| -62 | Two Surgeons | When two surgeons of different specialties perform distinct portions (rare for RARP; occasionally used if urologic oncologist + reconstructive surgeon) |
| -22 | Increased Procedural Services | Exceptional complexity (e.g., prior pelvic radiation, prior TURP, morbid obesity, salvage RP); must be documented with detailed operative note explaining increased time/difficulty |
| -52 | Reduced Services | Procedure substantially less than typically required (e.g., aborted prior to anastomosis) |
| -53 | Discontinued Procedure | Procedure stopped due to medical emergency (e.g., cardiac event intraoperatively) |
| -58 | Staged Procedure | Subsequent procedure planned/staged within global (e.g., continent diversion performed later) |
| -78 | Unplanned Return to OR | Return for complication within global period (e.g., anastomotic leak requiring repair) |
| -79 | Unrelated Procedure During Global | Completely unrelated surgery within 90-day global |
| -24 | Unrelated E/M During Global | Postop office visit for unrelated condition |
| -32 | Mandated Services | Workersβ comp or other mandated service contexts |
| -GA | Waiver of Liability on File | ABN-related; rarely applicable for cancer surgery |
| -LT / -RT | Left/Right Side | Not typically applicable to prostate (midline organ); may apply if nerve sparing documented unilaterally for billing documentation purposes |
π¨ MS-DRG (Inpatient)
55866 is frequently performed as an inpatient procedure, particularly when PLND is performed concurrently, robotic time is extended, or the patientβs comorbidity burden warrants overnight or 23-hour observation/admission. For inpatient admissions, the ICD-10-PCS procedure code is reported on the UB-04.
ICD-10-PCS Equivalents
| ICD-10-PCS | Description | Notes |
|---|---|---|
0VT04ZZ | Resection of Prostate, Percutaneous Endoscopic | Primary PCS code for robotic/laparoscopic radical prostatectomy |
0VT07ZZ | Resection of Prostate, Via Natural or Artificial Opening | Rarely used for RP |
07BC4ZX | Excision of Pelvic Lymphatic, Percutaneous Endoscopic, Diagnostic | Laparoscopic pelvic lymph node sampling (diagnostic/biopsy) |
07BC4ZZ | Excision of Pelvic Lymphatic, Percutaneous Endoscopic | Laparoscopic pelvic lymphadenectomy (therapeutic/staging) |
07BB4ZZ | Excision of Left Inguinal Lymphatic, Percutaneous Endoscopic | If extended dissection performed |
PCS Root Operation for Radical Prostatectomy: Resection (T) β cutting out or off, without replacement, all of a body part. This distinguishes from Excision (B), which is partial. A radical prostatectomy removes the entire prostate gland; therefore, Resection is the correct root operation.
PCS Root Operation for Pelvic Lymph Node Dissection: Excision (B) with qualifier Z (No Qualifier) for therapeutic, or X (Diagnostic) for sampling/biopsy.
MS-DRG Assignment
| MS-DRG | Description | Type | Typical Scenario |
|---|---|---|---|
| 715 | Other Male Reproductive System O.R. Procedures for Malignancy with MCC | Surgical | C61 + MCCs (e.g., respiratory failure, sepsis, C77.5) |
| 716 | Other Male Reproductive System O.R. Procedures for Malignancy with CC | Surgical | C61 + CCs (e.g., N40.1, E11.9, I10) |
| 717 | Other Male Reproductive System O.R. Procedures for Malignancy without CC/MCC | Surgical | C61 only, no significant comorbidities |
| 729 | Other Male Reproductive System O.R. Procedures with MCC | Surgical | If principal dx is not malignancy-related |
| 730 | Other Male Reproductive System O.R. Procedures with CC | Surgical | Non-malignancy principal dx with CC |
| 731 | Other Male Reproductive System O.R. Procedures without CC/MCC | Surgical | Non-malignancy, no comorbidities |
π₯ Inpatient Coder Note β MS-DRG Optimization Tips:
- C61 as principal diagnosis routes to the 715-717 DRG triplet (malignancy-specific), which typically carries higher relative weights than the 729-731 triplet
- C77.5 (pelvic lymph node metastases, confirmed on PLND) codes as an MCC in many grouper versions β this alone can move a case from DRG 717 β 715, significantly impacting reimbursement
- Comorbidities such as E11.9 (Type 2 DM), I10 (hypertension), N17.9 (acute kidney injury), and J44.1 (COPD exacerbation) may qualify as CCs or MCCs, impacting DRG assignment
- Ensure the attending physician documents all comorbidities managed during the stay β query for conditions such as perioperative hypertensive urgency, blood transfusion indications, and post-op urinary retention as these may carry CC/MCC status
- Prolonged LOS alone does not change the DRG β focus on documented and coded CCs/MCCs
DRG Relative Weights (Approximate β FY2025)
| MS-DRG | Relative Weight | Geometric Mean LOS |
|---|---|---|
| 715 | ~4.2 | ~6.5 days |
| 716 | ~2.4 | ~3.8 days |
| 717 | ~1.5 | ~2.1 days |
π Coding Examples
π’ Example 1 - Standard Robotic Radical Prostatectomy, Organ-Confined Disease, No PLND
Clinical Scenario: A 58-year-old male with Gleason 7 (3+4) prostate cancer, clinical stage T2bN0M0, PSA 8.4. Low-intermediate risk. Robot-assisted laparoscopic radical prostatectomy performed with bilateral nerve sparing. No pelvic lymph node dissection performed (low-intermediate risk, Briganti nomogram <5% LN involvement). Estimated blood loss 150 mL. Specimen sent to pathology; final path: pT2c, Gleason 3+4=7, negative margins, seminal vesicles negative.
CPT Codes (Professional/Outpatient ASC):
- 55866 - Laparoscopic robotic radical prostatectomy with nerve sparing
ICD-10-CM:
- C61 - Malignant neoplasm of prostate (primary indication)
Inpatient UB-04 (ICD-10-PCS):
- Principal Dx: C61
- Procedure:
0VT04ZZ- Resection of Prostate, Percutaneous Endoscopic
MS-DRG: 717 (no CCs/MCCs) or 716 if comorbidities documented and coded
π’ Example 2 - Robotic Radical Prostatectomy WITH Bilateral Pelvic Lymphadenectomy
Clinical Scenario: A 63-year-old male with Gleason 4+4=8 (Grade Group 4) prostate cancer, clinical T3aN0M0, PSA 18.2. High-risk disease. RARP performed with bilateral nerve-sparing attempt on left side (non-nerve sparing on right per intraoperative findings). Bilateral extended pelvic lymph node dissection performed, removing external iliac, obturator fossa, and hypogastric nodal packets bilaterally. Final path: pT3a, Gleason 4+4, left margin positive, 2/18 pelvic lymph nodes positive for metastatic adenocarcinoma.
CPT Codes:
- 55866 - RARP with nerve sparing (unilateral attempt; bilateral descriptor still applies)
- 38571 - Laparoscopic bilateral pelvic lymphadenectomy (separately reportable; PLND not included in 55866)
ICD-10-CM:
- C61 - Malignant neoplasm of prostate
- C77.5 - Secondary malignant neoplasm of intrapelvic lymph nodes (confirmed on pathology)
Inpatient UB-04 (ICD-10-PCS):
- Principal Dx: C61
- Secondary Dx: C77.5 β MCC β routes to DRG 715
- Procedures:
0VT04ZZ- Resection of Prostate, Percutaneous Endoscopic07BC4ZZ- Excision of Pelvic Lymphatic (bilateral), Percutaneous Endoscopic
MS-DRG: 715 (malignancy + MCC from C77.5)
π‘ Coder Note: The positive lymph nodes (C77.5) discovered intraoperatively or on final pathology must be coded on the inpatient claim when confirmed during that admission. C77.5 as an MCC dramatically impacts DRG weight and reimbursement β do not miss this.
π’ Example 3 - Robotic RP with Increased Complexity (Prior TURP, Obesity)
Clinical Scenario: A 71-year-old male with known prostate cancer (C61), Gleason 7 (4+3), prior transurethral resection of prostate (TURP) 4 years ago, BMI 42 (morbid obesity). RARP performed; surgery required 6.5 hours due to extensive adhesions from prior TURP, obliterated tissue planes, and obesity-related technical difficulty. Operative note explicitly documents βsignificantly increased operative time, complexity, and risk due to prior TURP scarring and morbid obesity.β
CPT Codes:
- 55866 - -22 - RARP with increased procedural services (modifier -22 requires documentation of unusual complexity and will likely require a cover letter to payer)
ICD-10-CM:
- C61 - Malignant neoplasm of prostate
- E66.01 - Morbid (severe) obesity due to excess calories (documents medical necessity for modifier -22)
- Z87.891 - Personal history of other specified conditions (prior TURP)
Note: Modifier -22 should be submitted with a cover letter explaining the unusual circumstances. CMS does not have a specific process for -22 but allows it; commercial payers vary. Expect 10-30% additional reimbursement consideration if approved.
π’ Example 4 - Inpatient Admission, Return to OR Within Global (Anastomotic Leak)
Clinical Scenario: Patient underwent RARP on Day 1 of admission. Discharged POD2. Readmitted POD5 with pelvic abscess and anastomotic leak. Return to OR for laparoscopic washout and drain placement.
CPT Codes (Return to OR):
- 49323 - Laparoscopy, surgical; with drainage of lymphocele or cyst (if lymphocele) β or appropriate laparoscopic washout code
- Append modifier -78 - Unplanned return to OR for complication during global period
ICD-10-CM:
- T81.32XD - Disruption of internal operation wound, subsequent encounter
- C61 - Underlying reason for original surgery (active malignancy)
- K65.1 - Peritoneal abscess (pelvic)
Inpatient Note: Second admission is a separate encounter; code the complication as principal diagnosis for the second admission. C61 is secondary.
π’ Example 5 - Assistant Surgeon Billing (Bedside Robotic Assistant)
Clinical Scenario: PA-C serves as bedside assistant during RARP. Attending urologist operates at robotic console. PA-C manages instruments at bedside, assists with exposure, and manages specimen extraction.
CPT Code (PA billing):
ICD-10-CM:
- C61 - Malignant neoplasm of prostate
Payment: Medicare reimburses -AS modifier at 85% of the 16% assistant surgeon allowable = approximately 13.6% of the primary surgeonβs allowed amount. Commercial payers vary widely.
β οΈ Common Coding Pitfalls
- β Do not separately bill for robotic assistance (e.g., S2900) on the professional claim β it is bundled into 55866 by AMA descriptor; most payers will deny S2900 as a professional service
- β Do not assume PLND is included in 55866 β unlike open codes 55845/55815, laparoscopic PLND is separately reportable with 38571 or 38572
- β Do not use 55840 (open retropubic RP) for a robotic case β even if documentation says βretropubic approach,β if it was performed laparoscopically/robotically, 55866 is correct
- β Do not bill 55866 + 55840 together β they represent the same procedure via different approaches; report only one
- β Do not code Z85.46 (personal history of prostate cancer) during the same admission as the radical prostatectomy β C61 is the active cancer being treated
- β Always query the surgeon regarding nerve sparing laterality β while both unilateral and bilateral are bundled into 55866, documentation of nerve sparing affects prognostic coding and clinical completeness
- β Always review the final pathology report for lymph node status β positive nodes (C77.5) carry HCC 8 status and MS-DRG MCC designation; missed diagnosis = significant undercoding
- β
Verify the operative note documents βpercutaneous endoscopicβ or βlaparoscopicβ approach for PCS β
0VT04ZZrequires the 4th character =4(Percutaneous Endoscopic); a hand-assisted laparoscopic approach may require a different character value - β Modifier -22 requires both a detailed operative note AND typically a cover letter β submit proactively with the claim rather than waiting for a denial
- β During the 90-day global period, routine follow-up visits are bundled; only separately billable encounters are those for unrelated conditions (-24), staged procedures (-58), or complications requiring OR return (-78)

A few highlights specific to 55866 worth noting for your workflow:
- The PLND distinction (bundled in open codes, separately reportable in 55866) is the single most impactful billing nuance for this code β it catches a lot of coders off guard
- The C77.5 β HCC 8 / MCC pathway is a high-value documentation opportunity that often goes uncoded when the PLND is performed but node-positive results come back after discharge
- The PCS root operation distinction (Resection vs. Excision) for inpatient coding is critical β the whole gland = Resection (
T), not Excision (B)
