Summary & Overview

CPT 55821: Open Prostatectomy via Lower Abdominal (Suprapubic) Approach

CPT code 55821 denotes an open prostatectomy performed through a lower abdominal (suprapubic) incision with removal of the prostate gland and vas deferens and incision/enlargement of the urethra to relieve obstruction. The procedure addresses tumors or persistent benign prostatic enlargement that obstruct urinary flow and may be staged across two surgeries. Nationally, this code represents a major urologic operative service with implications for surgical resource use, inpatient and ambulatory surgical workflow, and postoperative care.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the service, typical sites of care, common modifiers used with the code, and how the code fits into surgical service lines. The publication outlines billing and coding considerations, typical utilization patterns for open prostatectomy relative to minimally invasive alternatives, and operational benchmarks where available. Data not provided in the input are noted as unavailable.

Billing Code Overview

CPT code 55821 describes a surgical procedure in which the provider performs an excision of the prostate gland (prostatectomy) through a lower abdominal incision in the skin crease above the pubic bone. The procedure includes removal of the vas deferens and enlargement/incision of the urethra to restore urinary flow, with measures taken to control blood loss. The described operation is typically performed to treat a prostate tumor or persistent prostatic enlargement that is obstructing urinary flow and may be staged across two separate procedures.

Service type: Open surgical prostatectomy with urethral incision and hemostasis
Typical site of service: Inpatient or outpatient operating room in a hospital or ambulatory surgical center

Clinical & Coding Specifications

Clinical Context

A 68-year-old male presents with progressive urinary retention, nocturia, weak urinary stream, and incomplete bladder emptying. Evaluation with history, physical exam, serum PSA, urinalysis, and transrectal ultrasound demonstrates a markedly enlarged prostate with obstructive symptoms refractory to medical therapy. Imaging and biopsy exclude metastatic disease but confirm significant benign prostatic hyperplasia or a localized prostate tumor causing outlet obstruction. The urologic surgeon schedules an open suprapubic prostatectomy via a lower abdominal skin crease incision to excise the prostate gland and the vas deferens, perform urethral internal sphincterotomy or enlargement of the urethral meatus as needed, and achieve hemostasis.

Preoperative workflow includes informed consent, optimization of anticoagulation, anesthesia evaluation, and preoperative antibiotics. Intraoperative steps include a lower midline or transverse suprapubic incision, cystotomy or access to the prostate adenoma through the bladder neck, enucleation of the adenomatous tissue or excision of the gland and vas deferens, urethral incision/enlargement as required, and meticulous hemostasis with sutures or cautery. Postoperative care includes urinary catheter drainage, monitoring for bleeding and infection, pain control, and follow-up for catheter removal and assessment of urinary function.
