Consumer Guidance & Cost Commentary

For the CPT code 83735 (Blood test, magnesium) at Saint John Hospital in Leavenworth, KS, the facility's cash median rate is $6.00, which is significantly lower than the negotiated rates paid by insurance plans ranging from $7.00 to $26.00. While the facility's negotiated rates are higher than the cash price, patients with high-deductible plans may find that paying out-of-pocket is more cost-effective if their insurance allowed amount exceeds the cash rate. It is important to note that commercial rates often include administrative overhead and contract dynamics that can inflate the baseline price, whereas the cash price reflects a direct transaction without these layers.

The facility's cash rate of $6.00 is notably lower than the Medicare benchmark of $6.70, suggesting that the cash price is already competitive relative to the federal government's cost-based reimbursement standard. However, patients should be aware that insurance negotiated rates can sometimes exceed the cash price due to the administrative costs and claim processing fees embedded in commercial contracts. To ensure you receive the best possible rate, it is recommended to explicitly ask the hospital about "self-pay" or "prompt-pay" discounts before scheduling, as these upfront incentives can further reduce the final cost. Additionally, if you receive a bill from an out-of-network provider, you may be eligible for protections under the No Surprises Act, which prevents balance billing for emergency care and non-emergency services at in-network facilities.
