Summary & Overview
CPT 49491: Premature-Infant Inguinal Hernia Repair
CPT code 49491 denotes surgical repair of a reducible inguinal hernia in a premature infant (born before 37 weeks), performed from birth until 50 weeks after conception; the procedure can include excision of an associated hydrocele. This code captures a distinct pediatric surgical service with implications for neonatal surgical scheduling, resource use, and payer reimbursement policy across national programs and commercial insurers. Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare.
Readers will learn the clinical context and typical care setting for CPT code 49491, how payers commonly classify and reimburse neonatal inguinal hernia repair, and what benchmarks and policy considerations affect coverage and timing of the repair. The publication reviews surgical service characteristics, typical site-of-service patterns (operating room, ambulatory surgical center, or inpatient neonatal surgery), and how payers approach claims for procedures performed in the early postnatal period. Where available, the report highlights reimbursement ranges, prior authorization and medical necessity themes, and coding practices that affect billing accuracy. Data not available in the input is noted as such in relevant sections.
Billing Code Overview
CPT code 49491 describes surgical repair of a reducible inguinal (groin) hernia in a premature infant born before 37 weeks' gestation. The repair is performed during the neonatal period extending from birth until 50 weeks after the original date of conception. The procedure may include excision of an associated hydrocele in the scrotum when present.
Service Type: Surgical procedure — pediatric/ neonatal hernia repair
Typical Site of Service: Operating room / ambulatory surgical center or other inpatient neonatal surgical setting depending on the infant's clinical status and timing of repair.
Clinical & Coding Specifications
Clinical Context
A premature male infant born at 34 weeks' gestation presents with a reducible inguinal hernia identified on physical exam during the newborn nursery stay or shortly after discharge. The infant may have an associated communicating hydrocele with scrotal swelling. The typical workflow involves initial evaluation by the neonatal or pediatric team, referral to pediatric surgery, preoperative assessment including weight and cardiorespiratory stability, and anesthesia evaluation (often pediatric or neonatal anesthesia). Surgery is scheduled any time from birth until 50 weeks after the original date of conception; many cases are performed before the infant reaches term-equivalent age if risk of incarceration or symptoms exist. The procedure is performed in an operating room or pediatric procedure suite with standard sterile technique, and may be done under general anesthesia with appropriate neonatal monitoring. Postoperative care includes recovery in the post-anesthesia care unit or neonatal intensive care unit as indicated, analgesia, wound care, and follow-up for assessment of wound healing and recurrence.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | Reserved for national assignment | Do not use unless directed by payer |
11 | Physician or other qualified health care professional service | Use to indicate the usual, non-modified service when a modifier is required by billing rules |
22 | Increased procedural services | Use when work, time, or difficulty substantially exceeds typical for the procedure (document rationale) |
23 | Unusual anesthesia (for procedures usually not requiring general anesthesia) | Use if the procedure required significant additional anesthesia due to the infant's condition |
26 | Professional component | Use if billing only the professional component separate from technical component (rare for operative CPT) |
52 | Reduced services | Use when a surgeon intentionally performs less than full procedure (document reason) |
53 | Discontinued procedure | Use if the procedure was started but halted due to extenuating circumstances |
62 | Two surgeons | Use when two surgeons of different specialties are required and both contribute |
63 | Procedure performed on infants less than 4 kg | Use specific payer-directed modifier for low-birth-weight infants when applicable (some payers require for neonatal procedures) |
66 | Surgical team approach | Use when team surgery is required for complex neonatal cases |
78 | Return to OR for related procedure during postoperative period | Use if reoperation is performed for a complication related to the initial repair |
79 | Unrelated procedure during postoperative period | Use if an unrelated procedure is performed during the global period |
50 | Bilateral procedure | Use if bilateral inguinal hernia repairs are performed and payer requires bilateral modifier instead of separate coding |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
| 207P00000X | Pediatric Surgery | Most common specialty performing neonatal inguinal hernia repair |
| 2080P0206X | Pediatric Anesthesiology | Provides anesthesia for neonatal surgical procedures |
| 208000000X | General Surgery | May perform infant hernia repairs in some centers |
