What this provider does (Medicare)

Based on Medicare fee-for-service claims, 2024; not all care is captured.

Service (HCPCS)	Medicare services	Typical Medicare-allowed (2024)
Repair of Sliding Groin Hernia49525	11	$104
Initial Repair of Entrapped Hernia of Abdomen, Less Than 3 Cm in Length49592	11	$87

Typical Medicare-allowed amounts for these services range $87–$104 (2024). The Medicare-allowed amount is what Medicare recognizes for a service under fee-for-service — a reference figure for 2024, not a price quote and not what you would be billed. Medicare Part B covers roughly an eighth of all NPIs (65+ skew); services with fewer than 11 beneficiaries are suppressed by CMS.
