Some MU2 measures currently use "Measurement Start Date" and "Measurement End Date", although these concepts were never documented in the QDM specification. These concepts are unnecessary since they can be modeled just as simply using timing operators with "Measurement Period".
To encourage more consistency, we recommend removing "Measurement Start Date" and "Measurement End Date". The following table shows existing usage and recommended usage for MU2 measures:
| Existing | Recommended | CMS Measures |
|---|---|---|
| starts before start of "Measurement Start Date" | starts before start of "Measurement Period" | 160v2 169v2 |
| starts before start of "Measurement End Date" | starts before end of "Measurement Period" | 133v2 |
| starts before or during "Measurement End Date" | starts before end of "Measurement Period" | 138v2 141v3 160v2 |
| starts after start of "Measurement Start Date" | starts after start of "Measurement Period" | 160v2 169v2 |
| ends before or during "Measurement End Date" | ends before end of "Measurement Period" | 160v2 |
| ends after start of "Measurement Start Date" | ends after start of "Measurement Period" | 160v2 |
