What this record shows
This record is dominated by food and beverage: $1,612 of the $1,806 with a category attached, or 89.2%. It is spread thinly across 22 manufacturers, the largest accounting for just 13.7% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $980 and has fallen 98.0% since, to $20 in 2024. That places this record below the midpoint for urology clinicians in TX, where the typical reported total is $3,394.
