<p> The VSAC Web browser provides a way to query and filter the Value Set Repository. This is useful for
an overall view of the value sets and their metadata. The VSAC Web browser application also allows
you to download value sets in XML format, Excel spreadsheets, or Text. Use the filters and your
search terms to narrow your results. </p>
<ol style="list-style: none">
<li> <strong>Query:</strong> All value sets in the VSAC repository are automatically displayed when
you first visit the <strong>Search Value Sets</strong> page. You can enter search terms directly
into the Query box to refine your results. For example, you can type the term 'heart' and click
the <strong>Search</strong> button to retrieve all value sets that contain the word 'heart' in a
value set name, code descriptor, or in a term that is algorithmically mapped to the word
'heart.' You can search by a specific object identifier (OID) for a value set.
You can search by a specific terminology code to retrieve a list of all value sets that contain that code.

</li>
<li> <strong>Refine Search:</strong> To refine your search, select to search by a particular
program; e.g., CMS eCQM, HL7 C-CDA, CMS Hybrid, and CMS Pre-rulemaking eCQM. Also, to refine
your search further, select a particular steward(s), and/or a code system(s). <br /> <br /><img
class="img-fluid" src="/vsac/support/usingvsac/searchvsrefine2.png" id="refine"
alt="Refine Search" /> <br /><br /> </li>
<li> <strong>Sort and Filter Search Results</strong> The Search Results table initially displays all
value sets contained within the VSAC repository. When you enter query terms, or codes, and then
apply your desired filters, the Search Results table displays the value sets retrieved by your
search. The total number of retrieved value sets is displayed at the top, middle part of the
Search Results Table. To sort your Matched Value Sets results click on any column heading: name,
code system, definition type, steward, OID, and code count. You can also use the filter boxes in
the first row to filter your results by specific terms. You can constrain your filter terms
using the following operations to the left of each filter box: ^ begins with , ~ contains , ==
equals. <br /> <br />

the hyperlinked OID for that value set. The Value Set Details view may display the following
panels:<br /> </p>
<ul>
<li> <strong>Value Set Information:</strong>
<ul>
<li> <strong>Expansion Versions:</strong> The expansion versions are snapshots in time of
the value set definition computed by VSAC using the latest available code system
version. The expansion is a code list calculation from the value set definitions created
by authors in the VSAC Authoring Tool using an author-designated expansion profile of
specified code system versions. The default expansion profile is the set of the most
recent code systems in VSAC. For CMS electronic Clinical Quality Measures (eCQMs),
select a particular release; e.g., eCQM Update 2017-05-05. <ul>
<li>
<p> <strong>Latest: </strong> The default Value Set Details view shows the
latest automatic update by VSAC as well as all value set updates that
authors publish. When new code system versions are published by their source
terminologies, VSAC will represent only the latest value set code membership
(expansion) of each published value set using these updated code system
versions. </p> <br /> <br /> <img class="img-fluid"

<p> <strong>Program Releases:</strong> Value set authors and stewards
periodically revise their value sets manually and approve them for
publication by a particular program. For example, the CMS updates the CMS
Clinical Quality Measure value sets annually. <br /><br /> <img
