Cystectomy is a surgical procedure involving the partial or complete removal of the urinary bladder, performed most often in the treatment of muscle-invasive bladder cancer (C67.9 and related codes), refractory bladder conditions, or, less commonly, removal of pathological cysts at other anatomic sites. It is distinct from a cystostomy (creating an opening into the bladder without removal) and cystorrhaphy (bladder repair), as cystectomy involves actual excision of bladder tissue. A partial cystectomy preserves the majority of bladder function by removing only a discrete segment of the bladder wall, whereas a radical cystectomy removes the entire bladder along with surrounding structures (prostate and seminal vesicles in males; uterus, ovaries, and anterior vaginal wall in females), typically necessitating urinary diversion. Following complete removal, urinary continuity must be re-established through a urinary diversion method such as an ileal conduit (Bricker procedure), ureterosigmoidostomy, or a continent neobladder. Cystectomy is commonly confused with cholecystectomy (gallbladder removal) due to the shared cysto- root — the key difference is anatomic: cystectomy refers to the urinary bladder unless otherwise specified (e.g., cholecyst- specifies the bile sac).
The word entered English in the 1880s as cystectomy (noun), formed from New Latin / medical Greek compound kystis (“bladder, sac”) + -ektomia (“excision”). The root kystis (“bladder, pouch”) connects Cystectomy to the entire -cyst- ROOT FAMILY: cystitis (inflammation of the bladder), cystoscopy (visual examination of the bladder), cystotomy (incision into the bladder), and cholecystectomy (removal of the gallbladder). The suffix -ectomy is one of the most productive surgical suffixes in medical terminology, appearing in appendectomy, nephrectomy, hysterectomy, prostatectomy, and thyroidectomy.

🔗 RELATED TERMS
Cystostomy — surgical creation of an opening into the bladder (without removal); used for drainage; contrast with cystectomy, which is excision
Cystotomy — incision into the bladder (not removal); shares the cysto- root; used to access the bladder interior (e.g., for stone removal)
Cystoscopy — endoscopic visual examination of the bladder and urethra; primary diagnostic tool preceding cystectomy; does not involve excision

Urinary diversion — re-routing of urine flow after bladder removal; encompasses ileal conduit, continent pouch, neobladder; integral component of complete cystectomy planning
Ileal conduit — the most common urinary diversion method following radical cystectomy; uses a segment of ileum; also called Bricker operation (CPT 50820)

CODING CORNER
🏥 ICD-10-CM CODES
Malignant Neoplasm of Bladder — Primary Indication for Cystectomy (C67)
Pelvic exenteration, complete, for vesical, prostatic, or urethral malignancy, with removal of bladder and ureteral transplantations, with or without hysterectomy and/or abdominoperineal resection of rectum and colon
Cystourethroscopy, with fulguration and/or resection of LARGE bladder tumor(s)
⚠️ Coding Note: For inpatient profee coding, the ICD-10-CM diagnosis should reflect the most specific bladder site (C67.0-C67.8) when documented by the physician — avoid defaulting to C67.9 (unspecified) if the operative report or pathology identifies the location. Cystectomy CPT codes 51570-51597 are a code family hierarchy — select the single most comprehensive code that reflects the full extent of surgery performed; do not stack multiple cystectomy codes from the same family. A critical undercoding alert: when a radical cystectomy is performed robotically or laparoscopically, no specific CPT exists — report 51999 with a detailed cover letter benchmarked to the open equivalent (e.g., 51590 or 51595), as many coders incorrectly report the open code for a robotic approach. Modifier -22 (increased procedural services) may be applicable when the operative complexity significantly exceeds the typical procedure (e.g., re-operative field, severe adhesions, obesity) — documentation must support the additional work. For same-day E/M with a major surgical procedure, append modifier -57 to the E/M code. When billing 51595 with a concurrent female urethrectomy (53210), NCCI bundles these codes — an appropriate -59 or -XU modifier may be appended only when documentation clearly supports the urethrectomy as separate and distinct from the cystectomy work.
