Inguinal Hernia Repair (Pediatric)

• Document age at surgery and use the correct age tier for CPT selection. For preterm patients, document birth gestational age and postconception age at surgery — both are required to distinguish 49491/49492 from 49495/49496
• Document weight at surgery for modifier -63 eligibility (<4 kg)
• State identification and protection of vas deferens and gonadal vessels explicitly
• Document reducibility (reducible vs. incarcerated/strangulated) — determines the code pair (even = reducible, odd = incarcerated for each age tier)
• Note whether contralateral exploration was performed and findings
• {'Document ligation level': 'at the internal ring (high ligation) is standard'}
• For males, confirm testicular position in the scrotum at case conclusion — document explicitly
• Hydrocelectomy is bundled in 49491-49501; document hydrocele management in the note but do not submit a separate CPT code

• Code selection is strictly age-based for open repair. Preterm infant (<37 weeks gestation at birth), from birth up to 50 weeks postconception age: 49491 (reducible, 12.22 wRVU) or 49492 (incarcerated/strangulated, 15.04 wRVU). Full-term infant younger than 6 months (or preterm >50 weeks postconception age): 49495 (reducible, 6.05 wRVU) or 49496 (incarcerated, 9.18 wRVU). Age 6 months to younger than 5 years: 49500 (reducible, 5.69 wRVU) or 49501 (incarcerated, 9.13 wRVU). Age 5 years or older: 49505 (reducible, 7.76 wRVU) or 49507 (incarcerated, 8.86 wRVU). Age is determined at the time of the procedure, not at consultation. Document birth gestational age and postconception age for preterm patients — these are required to select 49491/49492.
• Recurrent inguinal hernia (any age, any approach): 49520 (reducible, 9.74 wRVU) or 49521 (incarcerated, 11.19 wRVU). Sliding inguinal hernia (any age): 49525 (8.71 wRVU). For laparoscopic initial repair (any age): 49650 (6.20 wRVU). Laparoscopic recurrent repair: 49651 (8.17 wRVU). Per AAPC, the laparoscopic code replaces the age-based open code when the laparoscopic approach is used — do not apply age-based codes (49491-49507) to laparoscopic repairs.
• Bilateral repair at same session: apply modifier -50 (bilateral) to the appropriate age-based open code (e.g., 49505-50). For laparoscopic bilateral repair (49650), check your payer's bilateral policy — the Medicare bilateral indicator for 49650 differs from open codes, and some payers do not apply the standard 150% bilateral adjustment. Document both sides explicitly.
• Modifier -63 (procedure performed on infant less than 4 kg): applies to 49491/49492/49495/49496 and other eligible codes when patient weight is under 4 kg. Adds approximately 22.6% to the fee. Document weight at time of surgery.
• Hydrocelectomy is bundled into CPT codes 49491-49501 ('with or without hydrocelectomy' is in the descriptor). Do not separately bill hydrocelectomy codes (55040/55041) with a pediatric inguinal hernia repair — this is unbundling. Document hydrocele management in the note but do not submit a separate CPT.
• Concurrent orchiopexy for associated undescended testis: CPT 54640 (orchiopexy, inguinal or scrotal approach, 7.54 wRVU, 90-day global) is separately billable with modifier -51. This is a common concurrent pediatric procedure. Document the undescended testis, its location, and that it was mobilized and fixed in the scrotum.
• 90-day global: routine postoperative visit is bundled. Hydrocele or recurrence presenting after the global period are separately billable.
