🔪 CPT 55810 — Prostatectomy, Perineal Radical
Quick Reference
wRVU: 22.87 (baseline, pending 2026 CF adjustment) | Global Period: 090 | Assistant Payable: Yes | Bilateral Indicator: 0
Rule: CPT 55810 carries a 90-day global surgical package covering all related pre-, intra-, and post-operative care. It is not bilateral (the prostate is a single midline organ), so modifier -50 is never appropriate. Because this is a major open procedure, an assistant surgeon is commonly payable when documented as medically necessary.
📋 Clinical Description
CPT 55810 describes a radical perineal prostatectomy — complete surgical excision of the prostate gland, seminal vesicles, and immediately adjacent periprostatic tissue through a curved incision in the perineum, between the scrotum and anus, rather than through an abdominal or laparoscopic port. The bladder neck is reconstructed and anastomosed to the urethra to restore continuity of the urinary tract. This code stands in contrast to its retropubic sibling 55840 (open retropubic radical prostatectomy) and the minimally invasive 55866 (laparoscopic/robotic-assisted radical retropubic prostatectomy), both of which access the gland through an abdominal approach and more commonly incorporate concurrent pelvic lymph node dissection.
The perineal approach offers a shorter operative time and avoids abdominal wall dissection, but it does not permit simultaneous pelvic lymphadenectomy through the same incision — a key coding distinction from 55812 and 55815, which build on this code to report perineal prostatectomy with lymph node biopsy or pelvic lymphadenectomy, respectively. Selection of approach depends on tumor stage, surgeon expertise, and whether nodal staging is clinically indicated.
This procedure may be performed in the following clinical contexts:
- Definitive surgical treatment of clinically localized prostate adenocarcinoma with low nodal-metastasis risk — 1-3 sentence clinical rationale supporting perineal approach over retropubic when nodal dissection is not indicated.
- Salvage prostatectomy following failed radiation or focal therapy, when perineal access is favored due to prior abdominal or pelvic scarring.
- Patients with significant obesity or prior lower abdominal surgery, where perineal access reduces technical difficulty relative to a retropubic approach.
- Academic or high-volume urology centers maintaining perineal technique expertise for select surgical candidates.
- Cases where operative time or anesthesia risk favors the technically faster perineal exposure over robotic-assisted alternatives.
🔬 Anatomical & Procedural Considerations
| Variant | Mechanism | Key Notes |
|---|---|---|
| Standard Perineal Approach | Curved perineal incision with direct exposure of the prostatic apex, dissection of the prostate off the rectum, and division of the urethra and bladder neck. | Avoids abdominal cavity entry entirely; preferred when nodal staging is not required or has been performed separately. |
| Nerve-Sparing Modification | Careful preservation of the neurovascular bundles along the posterolateral prostate during dissection. | Not separately reportable with 55810; documentation should reflect technique but does not change the base code. |
| Combined with Prior Staging Lymphadenectomy | Patient undergoes separate laparoscopic pelvic lymph node dissection before or concurrent with (different session) the perineal prostatectomy. | Requires distinct operative sessions/reports; 55810 alone does not include nodal dissection, unlike 55812/55815. |
Clinical Pearl
If pelvic lymph node sampling or dissection is performed during the same operative session as the perineal prostatectomy, do not report 55810 — escalate to 55812 (with lymph node biopsy) or 55815 (with bilateral pelvic lymphadenectomy) instead, since these are the correct code selections for that combined service.
✅ Procedure Includes
- Perineal incision and surgical exposure of the prostate gland and seminal vesicles.
- Complete excision of the prostate, seminal vesicles, and immediately adjacent periprostatic tissue.
- Ligation and division of the urethra and bladder neck with subsequent vesicourethral anastomosis.
- Control of postoperative bleeding within the same operative session.
- Placement of a urethral catheter for postoperative bladder drainage.
- Closure of the perineal incision.
❌ Excludes / Do Not Report Together
| Code | Description | Relationship |
|---|---|---|
| 55812 | Prostatectomy, perineal radical, with lymph node biopsy(s) (limited pelvic lymphadenectomy) | Represents the same base perineal approach plus limited nodal staging; if any lymph node biopsy is performed in the same session, 55812 replaces 55810 rather than being reported in addition to it. |
| 55815 | Prostatectomy, perineal radical, with bilateral pelvic lymphadenectomy, including external iliac, hypogastric, and obturator nodes | Represents the same perineal approach plus extended bilateral nodal dissection; supersedes 55810 when full pelvic lymphadenectomy is performed concurrently. |
| 55840 | Prostatectomy, retropubic radical, with or without nerve sparing | A separate open surgical approach through the abdomen rather than the perineum; not interchangeable with 55810 and never reported together for the same prostatectomy. |
| 52649 | Laser enucleation of the prostate with morcellation, including control of postoperative bleeding, complete | A separate transurethral procedure for benign prostatic hyperplasia rather than cancer excision; inappropriate to report together when the clinical intent is oncologic, not obstructive, treatment. |
Bundling Alert
Because 55810 carries a 090-day global period, any related E/M visits, catheter management, or minor bedside procedures performed within the 90-day postoperative window are bundled into the surgical package and are not separately billable without an appropriate modifier (-24 for unrelated E/M, -78 for unplanned return to the OR, -79 for unrelated procedure). Auditors frequently flag inpatient claims where a hospitalist or covering provider bills unrelated postoperative visits without modifier -24, so accurate documentation of medical necessity for any separately billed service during the global period is essential.

Bilateral Billing Rules
The prostate is a single midline structure, so bilateral billing concepts and modifier -50 do not apply to 55810. Any bilateral component of care (such as bilateral pelvic lymphadenectomy) is captured instead through code selection (55815) rather than a bilateral modifier on this code.
🏷️ Modifier Reference
| Modifier | Name | When to Apply |
|---|---|---|
| -22 | Increased Procedural Services | Apply when the operative report documents significantly increased complexity or time, such as extensive adhesions from prior pelvic surgery or unexpected anatomic distortion. |
| -51 | Multiple Procedures | Apply when 55810 is reported with other significant procedures during the same operative session, though many payers apply this automatically. |
| -52 | Reduced Services | Apply when the physician elects to terminate or reduce the scope of the planned procedure, such as converting to a subtotal excision. |
| -53 | Discontinued Procedure | Apply when the procedure is started but terminated due to a threat to patient well-being before completion. |
| -59 | Distinct Service | Apply when a separately identifiable procedure unrelated to the prostatectomy is performed in the same session and would otherwise appear bundled. |
| -58 | Staged | Apply when a planned or anticipated related procedure occurs within the 90-day global period, such as a staged nodal dissection. |
| -78 | Return to OR | Apply when the patient requires an unplanned return to the operating room for a complication of the original prostatectomy within the global period. |
| -79 | Unrelated Procedure | Apply when an unrelated procedure is performed by the same physician during the global period. |
| -AS | Assistant at Surgery (non-physician) | Apply when a PA or NP serves as first assistant, as many payers require this modifier rather than -80/-82 for non-physician assistants. |
Modifiers -RT/-LT/-50/-E1-E4 are excluded as clinically inapplicable — the prostate is a single, non-lateralized midline organ.
🩺 Common ICD-10-CM Pairings
Primary Diagnosis Group
| ICD-10 | Description | HCC? | Notes |
|---|---|---|---|
| C61 | Malignant neoplasm of prostate | Yes | This is the principal driver for a radical prostatectomy and should be sequenced as the primary diagnosis whenever documentation confirms biopsy-proven adenocarcinoma. |
Secondary Group
| ICD-10 | Description | HCC? | Notes |
|---|---|---|---|
| N40.1 | Benign prostatic hyperplasia with lower urinary tract symptoms | No | Frequently coexists with prostate cancer and may explain preoperative voiding symptoms documented in the history. |
| R33.8 | Other retention of urine | No | Report when postoperative or preoperative urinary retention is separately documented and clinically evaluated. |
Etiology / Complication
| ICD-10 | Description | HCC? | Notes |
|---|---|---|---|
| Z85.46 | Personal history of malignant neoplasm of prostate | Yes | Assign on follow-up encounters after the prostate has been surgically removed and there is no evidence of recurrence. |
| N99.11 | Postprocedural urethral stricture | No | Report if a documented complication of the vesicourethral anastomosis develops during the postoperative course. |
Coding Specificity Reminder
C61 has no further subclassification, so specificity concerns center on confirming biopsy/pathology support before assignment rather than code granularity; ensure the pathology report is finalized and referenced in the discharge summary before finalizing the principal diagnosis for inpatient claims.
🏥 MS-DRG Considerations
When 55810 is the principal procedure performed for a confirmed diagnosis of prostate malignancy, the encounter typically groups to MS-DRG 707 (Major Male Pelvic Procedures with CC/MCC) or MS-DRG 708 (without CC/MCC), depending on documented comorbidities such as acute blood loss anemia or postoperative complications. Accurate DRG assignment depends heavily on complete secondary diagnosis capture, since the presence or absence of a qualifying CC/MCC is the sole differentiator between these two DRG tiers. Coders should review the entire inpatient stay, not just the operative note, for any documented complications that would support a higher-weighted DRG.
🔧 ICD-10-PCS Equivalents
| PCS Code | Full Description | Modality |
|---|---|---|
| 0VT08ZZ | Resection of Prostate, Via Natural or Artificial Opening | Open/Endoscopic hybrid, natural orifice approach |
| 0VT00ZZ | Resection of Prostate, Open Approach | Open surgical |
| 0VT04ZZ | Resection of Prostate, Percutaneous Endoscopic Approach | Minimally invasive |
| 0VBT0ZZ | Excision of Prostate, Open Approach | Open surgical, partial excision |
PCS Character Analysis
| Position | Character | Value | Definition |
|---|---|---|---|
| 1 | Section | 0 | Medical and Surgical, the primary PCS section for operative procedures. |
| 2 | Body System | V | Male Reproductive System, encompassing the prostate and related structures. |
| 3 | Root Operation | T | Resection — cutting out all of a body part without replacement, the correct root operation for a radical prostatectomy. |
| 4 | Body Part | 0 | Prostate, the specific anatomic target of the resection. |
| 5 | Approach | 0 | Open, reflecting the perineal incisional access used in this procedure. |
| 6 | Device | Z | No Device, since no implant or prosthesis is left in place during a standard radical prostatectomy. |
| 7 | Qualifier | Z | No Qualifier, as there is no additional procedural characteristic to capture for this resection. |
Root Operation Comparison
- Resection (T) is used here rather than Excision (B) because the entire prostate gland is removed, not merely a portion of it, which is the defining distinction coders must apply when reviewing operative documentation.
- Approach coding hinges on the perineal incision being classified as Open rather than Percutaneous, since it involves direct visualization and cutting through skin and soft tissue rather than needle/scope access alone.
📝 Coding Examples
Example 1
Clinical Scenario:
A 64-year-old male with biopsy-confirmed Gleason 7 prostate adenocarcinoma is admitted for elective radical perineal prostatectomy. The surgeon documents a standard perineal approach with complete excision of the prostate and seminal vesicles, vesicourethral anastomosis, and no evidence of nodal involvement on prior staging imaging. No lymph node dissection is performed during this session. The patient tolerates the procedure without complication and is discharged on postoperative day two with a urethral catheter in place.
| Field | Code | Rationale |
|---|---|---|
| CPT | 55810 | The documentation supports a standard perineal radical prostatectomy without concurrent nodal dissection, matching the base code descriptor exactly. |
| PDx | C61 | Biopsy-confirmed prostate adenocarcinoma is the clear indication and principal reason for the admission and procedure. |
Note
Confirm the pathology report supports malignant histology before finalizing C61 as principal diagnosis; if only a clinical suspicion exists without confirmed pathology, an alternative code reflecting the presenting sign or symptom may be more appropriate.
Example 2
Clinical Scenario:
A 59-year-old male undergoes planned radical perineal prostatectomy for localized prostate cancer, and the surgeon also performs a limited pelvic lymph node biopsy during the same operative session due to intraoperative concern for nodal spread.
| Field | Code | Rationale |
|---|---|---|
| CPT 1 | 55812 | Because lymph node biopsy was performed concurrently, the combined code 55812 replaces 55810 rather than being reported alongside it. |
| PDx | C61 | Malignant prostate neoplasm remains the primary diagnosis driving the combined procedure. |
Warning
Example 3
Clinical Scenario:
A 67-year-old male is three weeks post radical perineal prostatectomy (55810) for prostate cancer and is readmitted with a pelvic hematoma requiring an unplanned return to the operating room for evacuation. The surgeon who performed the original prostatectomy also performs the take-back procedure. The hematoma is documented as a direct complication of the original surgical bed.
| Field | Code | Rationale |
|---|---|---|
| CPT | 10140 | Incision and drainage of hematoma is the appropriate code for the take-back procedure addressing the postoperative complication. |
| PDx | T81.0XXA | Postprocedural hemorrhage/hematoma complicating a procedure is the correct principal diagnosis for this unplanned readmission encounter. |
Global period reminder
Because the readmission and take-back occur within the 90-day global period of the original 55810, modifier -78 must be appended to the take-back procedure to indicate an unplanned return to the operating room for a related complication, ensuring the claim is not denied as bundled into the original global package.
⚠️ Common Coding Pitfalls
- Pitfall 1: Reporting 55810 in addition to 55812 or 55815 when lymph node biopsy or dissection was performed in the same operative session, which duplicates work already captured in the more comprehensive combination code and will trigger payer edits.
- Pitfall 2: Applying modifier -50 or lateral modifiers (-RT/-LT) to 55810, which is never appropriate since the prostate is a single midline structure with no bilateral billing concept.
- Pitfall 3: Failing to append modifier -24 to unrelated E/M services rendered by the same physician during the 90-day global period, resulting in inappropriate denial or, conversely, failing to document medical necessity when the modifier is used.
- Pitfall 4: Sequencing a symptom code such as elevated PSA (R97.21) as principal diagnosis instead of C61 when pathology has already confirmed malignancy, which understates clinical severity and risk adjustment.
- Pitfall 5: Omitting documentation supporting an assistant surgeon’s medical necessity, leading to denied assistant-at-surgery claims despite modifier -80/-AS being appended.
- Pitfall 6: Confusing this open perineal approach with the laparoscopic/robotic retropubic approach (55866) when abstracting from an operative note that does not clearly state the surgical approach, resulting in an incorrect code selection.
