Real World Rates

One-liner: Rates that reflect services that are expected to fluctuate between encounters, such as % of charges, but all components of the formula used to derive the rate come directly from reported data.

These rates are the typical per diem, percent of charge, and other variable payment models common in contracts. While these rates are indeed the best possible rates to show for such provisions, their whole $ amounts are expected to fluctuate from claim-to-claim and thus require a slight discount in "defensibility" compared to Posted Rates. Since all of the components of the calcualtion come directly from the posted data, there would not be a more accurate way to arrive at the rate.

Examples would be:

  • 90% of charges and average charge of $50,000 are both reported in the MRF
  • $5,000 per diem and average length of stay of 2 days are both reported in the MRF

Raw Real World Rates​

These are unprocessed rates that reflect encounter-level variability, sourced directly from reported data.

Transformed Real World Rates​

These are rates processed through standardization where all components come from reported data.

Per Diem Transformations​

We multiply the Per Diem rate reported in the MRF by the medicare GLOS (geometric mean length of stay).

Percent of Charge Transformations​

We multiply Percent-of-Charge rates reported in MRF files by gross charges that were also directly reported by the hospital in MRF files.

Drug Dosage Standardized Transformations​

For some drug rates from hospital data, we need to standardize the dosage.

Canonical Rate Type Format​

Real world rates use the canonical rate type format: {category}: {rate_source} where:

  • Category indicates the processing level (raw, transform)
  • Rate Source identifies the specific rate column used

Common Abbreviations​

  • gc: Gross Charge
  • hosp: Hospital
  • perc_to_dol: Percentage converted to dollar amount
  • mult_glos: Multiplied by Geometric Length of Stay
  • std: Standardized
