HealthPlanExplorer.com: Search & parse insurance plan MRF Files
Been exploring the Transparency in Coverage Rule (https://www.cms.gov/healthplan-price-transparency) that forces every health insurer to publish their contract rates with every provider they have in network in a machine readable format (json files) These published files are massive (about a petabyte of data a month with individual files up to 20GB) and a PITA to dig through. We built HealthPlanExplorer.com to make it easy to search the files. You can: - choose any in network file (as many as you want) - search by National Provider Identifier (NPI) - search by CPT Code And…
HealthPlanExplorer.com: Search & parse insurance plan MRF Files launched on February 1, 2023 with 22 votes, #1,285 of 3,829 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 3 years on.
In plain words
HealthPlanExplorer.com helps users search and parse the massive machine-readable files that health insurers must publish under the Transparency in Coverage Rule. The tool allows searching insurance plan rates by National Provider Identifier or CPT code across multiple files and exports results as CSV. It is designed for anyone needing to access contract rate data from insurance providers without manually downloading and processing gigabyte-sized JSON files. The site makes accessible what would otherwise be extremely difficult to dig through.

https://price.hospital/ I'm attempting to make US hospital prices searchable and comparable after congress enacted price transparency. I'm aware that there are severe problems here as the prices are so opaque. The prices quoted are not the insurance-negotiated prices, it's taking time to load in and clean up all the data, hospital compliance with transparency is... mixed... But we have to move the ball forward somehow. Also the site is missing many obvious features that I'm hacking (like human-readable procedure names like "cat scan" = "ct imaging" but hey. All feedback…

New Zealand Members of Parliament are required to annually disclose their financial interests (shareholdings, directorships, consultancies, etc.) but this gets published annually as an unwieldy 80+ page PDF that's hard to search effectively. I processed structured data out of the PDF and built a searchable interface: https://open-register-of-pecuniary-interests.joshmcarthur.co.... You can search across all MPs' disclosed interests by name, company, or interest type. For example, you can quickly find which MPs have interests in specific sectors or companies, filter by category or…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
