Clinical Context
A typical patient is an adult male presenting with a symptomatic inguinal bulge, groin pain, or intermittent bowel obstruction symptoms. Imaging or clinical exam confirms a sliding inguinal hernia involving a portion of an intra‑abdominal organ (commonly sigmoid colon or urinary bladder) that forms part of the hernia sac wall. The clinical workflow includes preoperative evaluation (history, physical exam, focused imaging if indicated), informed consent emphasizing the sliding component and potential need for organ repair, preoperative optimization (medical clearance, anesthesia assessment), surgical repair under general or regional anesthesia using open or laparoscopic technique, intraoperative identification and reduction of the sliding organ, repair of the hernia defect (tissue repair or mesh reinforcement as appropriate), and postoperative monitoring for complications (bleeding, organ injury, recurrence). Typical perioperative documentation includes laterality, presence of sliding component, organ involved, technique (open vs laparoscopic), any drains placed, and estimated blood loss. Typical site of service is an ambulatory surgical center or hospital operating room. Service type is surgical repair of an inguinal hernia with sliding component (49525). Typical patient scenario: a 54‑year‑old male with enlarging right groin mass and intermittent constipation; exam reveals an incarcerated reducible right inguinal hernia; CT shows portion of sigmoid colon as part of the hernia sac; elected for open repair with mesh and possible bowel assessment under general anesthesia.
Coding Specifications
| Modifier | Description | When to Use |
|---|
00 | No modifier — standard reporting | Used when no specific modifier applies; reports the primary service as performed. |
| 22 | Increased procedural services | Use when work, time, or complexity substantially exceeds typical for 49525 (e.g., extensive adhesiolysis of sliding bowel).
| 23 | Unusual anesthesia | Use when procedure is performed under general anesthesia in a patient where local/regional anesthesia would normally be used and documented as medically necessary.
| 26 | Professional component | Use if billing professional component separately from technical facility charges (rare for surgical procedure billing).
| 50 | Bilateral procedure | Use when bilateral sliding inguinal hernia repairs are performed and payer requires bilateral modifier reporting.
| 51 | Multiple procedures | Use when 49525 is performed with other distinct procedures in the same operative session and payer requires multiple procedure reporting.
| 52 | Reduced services | Use when the service is partially reduced or not completed as originally planned (e.g., aborted repair due to unexpected instability).
| 53 | Discontinued procedure | Use when the procedure is terminated before completion for extenuating circumstances.
| 62 | Two surgeons | Use when two surgeons work together as primary surgeons during the same operative session for portions of the repair.
| 63 | Procedure performed on infants less than 4 kg | Use when patient meets weight criteria and payer requires this modifier for neonatal cases.
| 78 | Return to OR for related procedure during postoperative period | Use when patient returns to operating room for a related complication (e.g., hemorrhage, organ injury) after the initial 49525.
| 79 | Unrelated procedure during postoperative period | (Not in provided list; omitted)
| 80 | Assistant surgeon | Use when an assistant surgeon provides significant assistance and separate assistant fee is billed.
| 81 | Minimum assistant surgeon | Use when an assistant provides limited assistance and payer acknowledges reduced assistant fee.
| AS | Physician assistant, nurse practitioner, or clinical nurse specialist services | Use when those mid‑level providers perform qualifying services per payer rules.
| Taxonomy Code | Specialty | Notes |

| 207L00000X | General Surgery | Primary specialty performing inguinal hernia repairs, including sliding hernias. |
| 207K00000X | Colon and Rectal Surgery | Manages sliding hernias involving colonic segments or when bowel resection is needed.
| 207RC0000X | Thoracic Surgery | Rarely involved when sliding hernia includes bladder or intrathoracic considerations (less common).
| 2080P0004X | Pediatric Surgery | Performs inguinal hernia repairs in pediatric patients with sliding component.
| 293Z00000X | Urology | Involved when sliding component includes bladder or urologic structures and urologic repair is required.
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |

| K40.20 | Bilateral inguinal hernia, without obstruction or gangrene | Used when bilateral sliding hernias are repaired.

Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|
49505 | Repair initial inguinal hernia, age 5 years or older; reducible | Alternative primary inguinal hernia repair code used when no sliding component is documented; used for standard open repairs. |
| 49520 | Repair recurrent inguinal hernia, initial open repair | Used when hernia is recurrent; may be performed instead of 49525 if sliding component is not specified or for recurrent presentations.
| 49650 | Laparoscopic repair of inguinal hernia, any age; incarcerated or strangulated | Used for laparoscopic approach to complicated inguinal hernias; may be chosen instead of open 49525 when laparoscopic technique addresses sliding component.
| 49020 | Paracentesis, therapeutic (for ascites) | May be performed preoperatively in patients with ascites complicating hernia repair planning (ancillary procedure).
| 44120 | Enterotomy, repair of small intestine | Used if intraoperative enterotomy occurs during reduction of a sliding hernia and requires repair; billed in addition to 49525 if unrelated to hernia repair complexity.
| 57240 | Bladder repair, suture of bladder injury | Used when sliding hernia includes bladder and intraoperative bladder repair is required; reported in addition to 49525.
