# DEQM Gap Status Modifier Extension - Data Exchange For Quality Measures Implementation Guide v1.0.0-ballot

## Extension: DEQM Gap Status Modifier Extension 

Identifies detected care gap status.

**Context of Use**

### Mandatory Data Elements and Terminology

The following data-elements are mandatory (i.e data MUST be present).

**Each Extension Must Have:**

1. url: identifies the meaning of the extension

The DEQM Gap Status is a modifier extension and is used by the DEQM Gaps In Care DetectedIssue. The gap status allows the `not-applicable` code, which indicates the patient does not meet the initial population criteria for the measure. The gap status also allows the `open-gap` code, which indicates the patient has an open care gap as opposed to a `closed-gap` status. These different gap statuses will likely affect whether a DEQM Individual MeasureReport or a Detailed Care Gap Guidance Response is referenced in the DetectedIssue as evidence and the nature of the Guidance Response
