Start with the same reference. Two people can agree on a contract percentage and still reach different answers. Before debating the total, compare the amount each person multiplied.
The question: what does “110%” multiply?
A percentage is only one input. The reference might be tied to a particular schedule, period, locality, setting or component. Write those details beside the calculation rather than relying on a shorthand label.
A small example
Illustrative amounts, not Medicare rates. With a $100 reference, 110% gives $110. With a $120 reference, the same 110% gives $132. Both multiplications are correct; the $22 difference comes from the reference.
One useful check
- Put both reference sources side by side.
- Compare their scope, versions and applicable dates.
- Ask the contract owner to resolve any uncertainty before treating a result as payment due.
Put it to work
Read the guide to matching a reference. To plan an implementation review, build a contract test checklist. Use the checklist to record the expected conditions before running your own tests.

CMS PFS documentation explains the inputs used in a Medicare reference. For the dataset supported by DueMD, check the tool rather than this example.
