CPT 51080: Incision and Drainage of Perivesical Abscess

CPT code 51080 identifies a surgical incision and drainage procedure for an abscess adjacent to the urinary bladder (perivesical abscess). This procedure is clinically significant for managing localized pelvic infections that can cause severe pain, sepsis risk, and potential spread to adjacent structures. Nationally, accurate coding of this procedure affects claims processing, clinical documentation, and quality measurement for acute surgical care.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for CPT code 51080, typical sites of service, and the service type. The publication also provides benchmarking and reimbursement context, common modifiers and billing considerations, and any recent policy updates that affect coverage and claims adjudication. Additionally, the article outlines documentation elements that support medical necessity and appropriate coding, and links this procedure to related surgical and postoperative care considerations.

This summary is intended for clinicians, coding professionals, and policy analysts seeking a national-level reference on coding, clinical context, and payer coverage considerations for CPT code 51080.

Billing Code Overview

CPT code 51080 describes an open surgical procedure in which the provider incises an abscess adjacent to the urinary bladder and drains purulent material from the perivesical space. This procedure is intended to evacuate localized infection around the bladder to relieve symptoms and reduce the risk of spread.

Service type: Surgical incision and drainage of a perivesical abscess
Typical site of service: Operating room or procedure suite in an inpatient or ambulatory surgical setting, depending on clinical severity and need for anesthesia

Clinical & Coding Specifications

Clinical Context

A typical patient is a 45–70-year-old adult presenting to the emergency department or outpatient urology clinic with localized lower abdominal pain, fever, and urinary complaints such as dysuria or frequency. On examination there is suprapubic tenderness and possible fluctuance; imaging (ultrasound or CT) demonstrates a peri‑vesical fluid collection consistent with an abscess adjacent to the urinary bladder. The clinical workflow includes triage and initial resuscitation (vital signs, IV access, analgesia, and antibiotics), targeted imaging to confirm size and location of the abscess, preoperative consent and planning, and scheduling of an incision and drainage procedure. The procedure is performed under local, regional, or general anesthesia depending on patient status and abscess location; the provider incises the abscess, evacuates purulent material, irrigates the cavity, and places a drain if indicated. Post‑procedure care includes wound care instructions, antibiotic therapy targeted to culture results, pain control, and outpatient or inpatient follow‑up with urology or primary care for monitoring and drain removal if placed.

Coding Specifications

Modifier	Description	When to Use
`00`	No modifier — standard reporting	Use when no specific modifier applies to the service provided
`11`	Office or outpatient visit — occasionally used as an institutional internal indicator	Rarely used; apply only if institutional convention requires indicating routine service
`22`	Increased procedural services	Use when work or resource intensity substantially exceeds usual requirements for incision and drainage of peri‑vesical abscess
`23`	Unusual anesthesia	Use when the procedure required general anesthesia or other unusual anesthesia for a minor procedure due to patient condition
`52`	Reduced services	Use when the procedure was partially reduced or not completed as originally planned
`53`	Discontinued procedure	Use when the procedure was started but terminated due to extenuating circumstances or patient instability
`54`	Surgical care only	Use when only the surgical portion is billed separately and pre/post care is billed by another provider
`55`	Postoperative management only	Use when only global postoperative care (e.g., wound checks, drain management) is billed
`62`	Two surgeons	Use when two surgeons of different specialties perform distinct parts of the procedure
`66`	Surgical team	Use when multiple surgeons participate as a team for a complex case
`78`	Unplanned return to OR by same physician following initial procedure	Use when patient returns to OR for complications related to the initial incision and drainage
`80`	Assistant surgeon	Use when an assistant surgeon performs portions of the procedure and modifier reporting is required
`81`	Minimum assistant surgeon	Use when a minimal assistant role is documented
`26`	Professional component	Use when billing separate professional component services that are reportable for this procedure (e.g., interpretive services)

Taxonomy Code	Specialty	Notes
208000000X	Urology	Most common specialty performing peri‑vesical abscess incision and drainage
207Q00000X	Colon & Rectal Surgery	May be involved when abscess proximity to pelvis or rectum requires their expertise
207L00000X	General Surgery	Performs drainage when urology is not available or for complex pelvic abscesses
2086S0203X	Pediatric Urology	Applies when the procedure is performed in pediatric patients
363LF0000X	Emergency Medicine	Often performs initial bedside incision and drainage in the ED setting
