What the Data Says About Carbon Dioxide (bicarbonate) Level
Across 35 states with reporting providers, CPT code 82374 (Carbon Dioxide (bicarbonate) Level) shows a national average Medicare payment of $4.48 against an average billed charge of $8.59. That gap, a 1.9x markup, or 92% above the Medicare allowed amount, is not a meaningful ratio for this low-payment code, so treat the billed figure as a chargemaster reference point rather than a real-world price.

State-level variation is significant: Missouri reports the lowest average payment at $3.19, while Connecticut reports the highest at $4.78. A 50% spread this wide is typically a GPCI story: practice-expense and malpractice-premium components of the fee formula diverge sharply by locality even though the procedure code never changes.
