Hospital Price Transparency $10,000 Database Bounty

4 min read

On January 1, 2021, a US law was passed requiring hospitals to publish their prices in human and machine readable format. We would like to assemble the best open dataset of hospital prices in the US to aid researchers. To this end, we’re launching our second bounty! The $10,000 bounty will be divided based on the percentage of cells modified, last write wins, in any table in the database during the two month duration of the bounty. The bounty ends March 1, 2021 and payouts will be calculated and processed then.


Bounties on DoltHub are a way to pay users to wrangle data. Because Dolt has Git-style versioning, interesting payout methods like percentage of cells edited are possible. We will be publishing new bounties approximately monthly so join our Discord to stay apprised!

The Database

The database consists of three tables:cpt_hcpcs, hospitals, and prices .

The cpt_hcpcs table consists of three columns, code, short_description, and long_description. code is the CPT or HCPCS code for the service. The CPT code is a standard maintained by the American Medical Association. HCPCS is the Medicare standard. We believe most hospitals will publish using the CPT code but HCPCS codes will be used instead if the pricing data was published using HCPCS. CPT codes are numerical while HCPCS codes start with a letter followed by 4 numbers

The hospitals table has the columns npi_number, name, url, street_address, city, state, and zip_code. The url column needs to be populated with the url where the pricing data can be found. The npi_number is the 10 digit national provider identifier for the corresponding hospital and name is the name of the hospital.

The prices table consists of four columns:

  1. code, with a foreign key constraint on the cpt_hcpcs table
  2. npi_number, with a foreign key constraint on the hospital table
  3. payer which is the insurer and takes on the value ‘CASH’ in the case where the payer is the individual, and
  4. price, the price of the medical shoppable service in USD.


I started by picking a hospital, Ben Taub hospital in Houston, TX and googled Ben Taub Hospital shoppable services, the second result had a reference to Hospital Price Transparency. Following the link, I found a zip download for the hospital’s Charge Description Master, which contains the descriptions, billing codes, and charge amounts for each service.

Unzipping the file yields an excel spreadsheet. In order to read it programmatically in python I rely on openpyxl. Next I google the NPI number for the hospital, which nets me the hospital’s NPI number and address, and I add them to the hospitals table. Now that’s complete, I can rev up a dolt mysql server dolt sql-server and run my script to add each of the entries in the Charge Description Master to the database.

You can look at the script here to help you get started.
