Consumer Guidance & Cost Commentary
For the blood test, magnesium procedure (CPT 83735) at Ascension Via Christi Rehabilitation Hospital Inc in Wichita, KS, the Medicare benchmark is $6.70. The facility's negotiated rate is $7.00, which is slightly higher than the Medicare amount. While commercial insurance contracts often result in rates significantly above Medicare, this specific service shows a minimal markup. Patients should note that cash-pay rates are not listed for this service, but in cases where insurance negotiated rates exceed cash prices, paying out-of-pocket can sometimes be more cost-effective, particularly for those with high-deductible plans. It is always advisable to contact the hospital directly to inquire about self-pay or prompt-pay discounts before scheduling, as these upfront payment incentives can reduce the final cost.
This data reflects pricing for the 2026-06 vintage and does not include state or county average comparisons for this specific code. However, it is important to understand that commercial insurance rates are contractually capped to protect members, yet they often include administrative overhead that can inflate the baseline price. If you receive a bill that seems unexpectedly high, you may be dealing with balance billing if you were treated by an out-of-network provider, though the No Surprises Act generally protects patients from such charges for emergency care and non-emergency services at in-network facilities. To ensure accuracy, always request a full itemized bill before making payments, as summary bills can obscure individual charges and potential errors. If discrepancies arise, a formal written audit dispute sent to the billing supervisor is the most effective way to resolve issues and avoid unnecessary debt.
