A worked example
Take the most disputed OB/GYN billing code, 58662, with a median qualifying payment amount of $534 in the files. A OB/GYN dispute with a qualifying payment amount of $534 resolves at the specialty median of 31.7x, an estimated award of $16,928. A median is not a floor or a ceiling: half of decided line items in the specialty resolve higher and half lower.
