penectomy is the surgical amputation or removal of all or part of the penis. Clinically, it is most frequently indicated for the definitive treatment of invasive penile malignancies, such as squamous cell carcinoma, when organ-sparing techniques are not feasible or have failed. The procedure is distinguished from circumcision (which removes only the prepuce) and emasculation (which involves the removal of both the penis and the testes). The underlying pathological mechanism necessitating the surgery is typically uncontrolled cellular proliferation (malignancy) invading the corpora cavernosa or urethra, though it may also be required for severe ischemic necrosis (e.g., secondary to Fournier’s gangrene) or catastrophic traumatic avulsion. Clinically relevant subtypes include partial penectomy (leaving a functional penile stump for upright micturition), total/complete penectomy (requiring a perineal urethrostomy), and radical penectomy (which includes en bloc removal of regional lymph nodes) (coded under CPT 54120-54135). It is commonly confused with orchiectomy; however, penectomy removes only the phallus, whereas orchiectomy removes the testicles, though both may be performed concurrently in advanced disease.
The word entered English in the 19th century as penectomy (noun), combining the Latin anatomical root penis with the Greek surgical suffix -ectomy — literally “surgical removal of the penis.” The root pen/o (“penis”) connects penectomy to the entire -penis root family: penile (pertaining to the penis), penitis (inflammation of the penis), and penoscrotal (pertaining to the penis and scrotum). The suffix -ectomy is highly productive in surgical medical terminology, appearing in hundreds of procedural terms such as orchiectomy, prostatectomy, and vasectomy.

Phalloplasty — the opposite/reconstructive counterpart of penectomy; the surgical construction or reconstruction of a penis, often performed post-penectomy or in gender-affirming surgery.
Orchiectomy — shares the -ectomy root; the surgical removal of one or both testicles, which may be performed concurrently with radical penectomy for advanced genitourinary cancers.
Perineal urethrostomy — a closely related clinical entity and mandatory concurrent procedure during a total penectomy; the surgical rerouting of the urethra to the perineum to allow voiding (CPT 53010).
Fournier’s gangrene — a complex necrotizing fasciitis of the perineum and genitalia that can rapidly destroy penile tissue, sometimes necessitating emergent partial or total penectomy for source control.
Lymphadenectomy — the surgical removal of lymph nodes; a critical component that distinguishes a simple total penectomy from a radical penectomy in oncologic staging and treatment.
Squamous cell carcinoma of the penis — the primary disease entity necessitating this procedure; a malignancy arising from the penile epithelium (ICD-10-CM C60.x).
Carcinoma in situ of penis — early-stage pre-invasive malignancy (e.g., Erythroplasia of Queyrat, Bowen’s disease) that may be treated with organ-sparing techniques but can progress to require penectomy (ICD-10-CM D07.4).
Penile biopsy — the primary diagnostic procedure associated with this term; used to confirm malignancy and depth of invasion prior to committing to amputation.
Urethrotomy or urethrostomy, external (separate procedure); perineal urethra, external (often bundled or billed with modifier -59 depending on NCCI edits and extent of primary procedure)
Inguinofemoral lymphadenectomy, superficial, including Cloquets node (separate procedure) (used if lymph node dissection is performed at a different session or not in continuity)
Unlisted procedure, male genital system (used for complex gender-affirming penectomy/vaginectomy combinations if no specific code applies)
⚠️ Coding Note: For inpatient profee coding under Noridian MAC (JE/JF), the critical distinction in the 54120-54135 family is the extent of the amputation and the inclusion of lymphadenectomy. Do not code a separate perineal urethrostomy (53010) with a complete penectomy (54125) unless explicitly supported by NCCI exceptions, as the creation of the urethral meatus is inherently included in the complete amputation work. When coding radical penectomy (54130, 54135), the bilateral lymph node dissections are included in the primary code; do not unbundle and bill 38760 or 38770 separately. An undercoding alert: ensure you query the provider if the operative report states “penectomy with node dissection” but does not specify whether the nodes were inguinofemoral (54130) or extended into the deep pelvic/iliac nodes (54135), as this significantly impacts wRVU assignment. Always sequence the primary malignancy (e.g., C60.9) first if the procedure is for oncologic control.
