Recently, there has been a significant push for more transparency in healthcare coverage. Patients and policymakers are demanding clearer information about healthcare costs. A crucial component of this transparency is the machine-readable files (MRFs) that hospitals release. These files disclose prices and negotiated rates for various services, making it essential for individuals to understand them to navigate the healthcare landscape effectively. In this blog post, we will explore how to analyze hospital MRFs, focusing on the CSV and JSON formats. We will also introduce Gigasheet, a powerful tool that simplifies this analysis.
Understanding Hospital Machine Readable Files (MRFs)
Machine-readable files are intended to make healthcare pricing data more accessible for analysis. The TiC (Transparency in Coverage) rule mandates that hospitals publish these files so consumers can easily compare costs across different providers. The two primary formats for MRFs are CSV (Comma-Separated Values) and JSON (JavaScript Object Notation).
CSV files are more user-friendly and work seamlessly with spreadsheet software like Excel (if they are under the ~1M row Excel limit). In contrast, JSON files can be complex and cumbersome, often leading to challenges in data handling.

The Challenges of Analyzing CSV Files
CSV files can be large and unwieldy, which can make working with them in spreadsheet software quite challenging. For example, a single MRF file could contain up to several million rows of data, detailing everything from negotiated rates to procedure codes. This overwhelming volume of information can quickly lead to confusion.
Excel, while a popular choice for data analysis, has limitations. It may struggle with files exceeding 1 million rows, risking crashes and loss of crucial information. In fact, studies show that 70% of Excel users have encountered issues with large datasets, which can significantly disrupt their analysis process.
The Complexity of JSON Files
JSON files introduce their own complications. Unlike CSV files, which lay out data in a simple tabular format, JSON structures information hierarchically. This complexity often causes users to miss valuable insights that could inform decision-making. For instance, manually navigating through a JSON file with thousands of entries can be daunting, leading many analysts to underestimate the richness of the data available.
Traditional spreadsheet software may not support JSON well, making it harder for analysts to work effectively with this format, especially when large datasets are involved. According to recent surveys, 60% of analysts reported that they find navigating JSON files challenging without proper tools.
Leveraging Gigasheet for Data Analysis
To tackle the limitations of both CSV and JSON files, a tool like Gigasheet can be transformative. This platform allows users to import significant data files without the restrictions that standard spreadsheet software has.
Gigasheet standardizes hospital JSON and payer files into a table format that’s easy to analyze. For example, instead of struggling with a JSON file containing nested data about various healthcare services, users can quickly organize and manipulate that information. This streamlining makes it possible to conduct more thorough analyses without getting bogged down.

Comparing Negotiated Rates Across Hospitals
One of Gigasheet's standout features is its ability to compare negotiated rates across different hospitals for specific services. Users can analyze data related to CPT (Current Procedural Terminology) codes, RC (Revenue Codes), HCPCS (Healthcare Common Procedure Coding System), and DRGs (Diagnosis-Related Groups).
For instance, if you are interested in the cost of an MRI, you can easily pull this data from MRFs for hospitals in your area. Analysts may find that costs can vary as much as 200% from one provider to another for the same service. This capability enables healthcare analysts to guide organizations toward making informed decisions based on financial implications.
Best Practices for Effective Data Analysis
When analyzing hospital MRFs, whether they are in CSV or JSON format, consider these best practices:
Familiarize Yourself with File Formats: Understand the differences between CSV and JSON. Knowing how each format structures data can significantly improve your analysis efficiency.
Utilize Standardized Metrics: Create a consistent framework for comparing data points. Use standard metrics like cost per procedure or average negotiated rates to enhance clarity.
The Future of Healthcare Data Transparency
As the trend towards healthcare data transparency continues to grow, tools like Gigasheet will become essential in data analysis. By simplifying how we handle vast amounts of information, organizations gain a better understanding of the healthcare market.
The requirement for hospitals to provide machine-readable files is just the start. Looking ahead, we need to continuously improve how we interact with healthcare data. This effort will enhance patient outcomes and potentially drive down costs.
So, Now What?
Transparency in healthcare is crucial for empowering providers and payers and enabling informed decision-making. Navigating machine-readable files from hospitals can feel daunting, especially when dealing with large CSV and JSON formats. However, tools like Gigasheet make this process more manageable, allowing users to extract meaningful insights and comparisons.
By gaining a deeper understanding of MRFs and leveraging advanced data analysis tools, healthcare stakeholders can promote transparency effectively. This shift doesn’t just benefit large organizations; it enhances the entire healthcare system. When players are better informed, the healthcare industry can adapt, fostering a more equitable system for everyone.
Embracing transparency and advanced analytical techniques can lead to significant positive changes in the healthcare landscape, benefiting both providers, payers and patients alike.
