Find the right worksheet for the job

Start with the question you are trying to answer. These links lead to separate tools on ClaimGrid, where you can enter your own information and read the sources and limitations for each worksheet.

Drug and pharmacy claims

For work involving a medication, its package identifier, or the time a supply may last.

A practical starting point

How to use a worksheet responsibly

A calculator can make arithmetic easier to inspect, but the result is only as useful as the inputs and assumptions behind it. A sensible workflow is:

01  Choose the task

Pick a worksheet that matches the service or claim question. Drug quantity, administration time, and payment are different questions and may need different tools.

02  Gather inputs

Use the information applicable to the actual task, such as documented times, package details, or values from a current payer or bureau worksheet. Do not enter patient identifiers.

03  Check the result

Read the tool's source and limitations, then compare its output with the current policy and documentation that govern your situation before acting on it.

Important limitation

ClaimGrid is an informational aid, not a substitute for professional judgment, current payer requirements, or review of a specific claim. It does not determine medical necessity. For the project's methodology and privacy information, see About & Methodology.
