Chiropractic Manipulative Treatment, 1-2 Spinal Regions98940	580	$30

Typical Medicare-allowed amounts for these services range $30–$30 (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.
