["Communication, Performed": "Macular Edema Findings Present"]

Performance/Reporting Period
Value Set Description from VSAC
Clinical Focus: This value set contains concepts that represent the presence of macular edema.
Data Element Scope: This value set may use the Quality Data Model (QDM) category related to Communication, or Diagnosis, or as an attribute to represent exam findings.
Inclusion Criteria: Includes only relevant concepts associated with the presence of macular edema.
Exclusion Criteria: Concepts that do not indicate macular edema are excluded from this value set.

Constrained to codes in the Communication, Performed: Macular Edema Findings Present value set (2.16.840.1.113883.3.526.3.1320)

QDM Datatype and Definition (QDM Version 5.4)

"Communication, Performed"

To meet criteria using this datatype, the communication indicated by the Communication QDM category is a conveyance of information from one entity (e.g., person, organization, or device) to another.

The Communication, Performed code represents the reason for the communication (i.e., the subject). The category attribute allows reference to the type, or category, of communication (e.g., notification, request, etc.). In many cases, the eCQM developer may not know the local workflow to address the type of communication; hence, it is listed as an attribute to be used as feasibility allows.


  • sent dateTime – when the communication was sent
  • received dateTime – when the communication was received

Note: Negation Rationale indicates a one-time documentation of a reason an activity is not performed. Negation of QDM datatype-related actions for a reason always use the author dateTime attribute to reference timing and must not use Relevant Period.

QDM Attributes


The time the data element was entered into the clinical software. Note, some datatypes include both Relevant Time and Author dateTime attributes. The purpose is to accommodate Author dateTime if the actual start and stop times are not available when evaluating for feasibility, and also to allow specification of a time for Negation Rationale.


The QDM attribute, negation rationale indicates the reason that an action was not performed. Only QDM datatypes that represent actions (e.g., performed, recommended, communication, order, dispensed) allow the 'negation rationale' attribute. The intent is to indicate a justification that such action did not happen as expected. This attribute specifically does not address the presence or absence of information in a clinical record (e.g., documented absence of allergies versus lack of documentation about allergies). QDM assumes that any information expected will be in a clinical record. The situation is different when something that normally would be expected to be done is specifically not done because of a valid clinical reason (such as the patient is allergic, they are suffering from a complication, or some other rationale. In this case, the 'thing not done' is rarely documented, especially as a code, in the patient record. To express such lack of evidence, an eCQM author should use a CQL 'not exists' expression noted in the examples, and they must also capture the Negation rationale to capture a reason for the absence, i.e., the reason must be included to qualify as a negation rationale type expression. The syntax in the human readable HQMF is described in CQL examples and in the MAT User Guide. Prior versions of QDM used the syntax, 'Procedure, Performed not done.' QDM 5.5 uses the syntax, 'Procedure, not Performed' and this is then associated with either a DRC or a value set used to identify 'the expected thing,' that in this case was not done. Negation Rationale attribute value indicates a one-time documentation of a reason an activity is not performed. Negation of QDM datatype-related actions for a reason always use the author dateTime attribute to reference timing.
