<h3>How to Create, Save, and Edit Value Sets</h3>
<p>The following tutorial supports any Authors who need to create value sets
as well as the measure developers and value set developers for the annual updates
of the electronic Clinical Quality Measure (eCQM) value sets. This tutorial
is useful for other purposes as well, beyond the eCQM value set annual updates.</p>
<p>Before you can create value sets, you need
<a href="https://www.nlm.nih.gov/vsac/support/usingvsac/author_registration.html">
VSAC Authoring Permissions</a>.
It is helpful to understand the
<a href="https://www.nlm.nih.gov/vsac/support/authorguidelines/authorstewardroles.html">
the roles of value set authors and stewards</a>. NLM expects all authors and stewards to review
the
<a href="https://www.nlm.nih.gov/vsac/support/authorguidelines/bestpractices.html">
VSAC Authoring Best Practices</a>.

<h4>Add Metadata</h4>
<p><strong> Mandatory fields </strong>: OID, Name, Author, Steward, Purpose Statements</p>
<h5>OID</h5>
<ul>
<li><strong>Object Identifier (OID) Assignment </strong> - We strongly encourage the auto generate
default setting in which VSAC automatically generates an OID for your value set once you have
entered all the information in the other fields, and have selected the "Save" button. If the
automatic OID assignment does not meet your purpose, you will need to enter your own OID
manually.
</li>
<li><strong>Manual Entry of OID (very rare)</strong> - You must first register your organization's
namespace with an OID registry, such as HL7, and your OID must be previously published and used
by
the value set community; the value set you create will have the same content and purpose of your
pre-existing OID. If your OID satisfies these requirements, uncheck the Auto Generate box under
the
OID field and follow these formatting rules:
<ul>
<li>OIDs consist of dot-separated digits [1-9] or 0 if a single digit number, leading zeros
are
not allowed in multi-digit numbers.</li>
<li>NLM OID name space: Your manually entered OID must not begin with this reserved NLM
namespace: 2.16.840.1.113762.1.4.</li>
</ul>
</li>
</ul>
<img class="figure-img img-fluid img-thumbnail" alt="OID.png"

<h5>Value Set Name and Purpose Statements</h5>
<p>Follow<a href="https://www.nlm.nih.gov/vsac/support/authorguidelines/bestpractices.html"> VSAC
Authoring
Best Practices</a> to write your value set Name and Purpose Statements.</p>
<h5>Save</h5>
<p>When finished entering metadata, click the "Save" button.</p>

src="/vsac/support/authorguidelines/extensionalcodesys.png">
</li>
<li>Add codes to your value set. Methods: SEARCH, IMPORT, ADD(+) <br /><br />
SEARCH
<ol type="a">
<li>Search and filter for codes in the Code Systems panel.</li>
<li>Select your desired codes, and click "&larr;Add to Value Set"</li>
<li>Save.</li>
</ol>
<img class="figure-img img-fluid img-thumbnail" id="searchcodes" alt="searchcodes.png"
src="/vsac/support/authorguidelines/searchcodes.png"><br /><br />
IMPORT
<ol type="a">
<li>Import a list of codes you have generated elsewhere.</li>
<li>Click "Import" in the Value Set Code List table.</li>
<li>Select the character that separates the codes you are copying to the Text Box or in the
file
you are importing.</li>
<li>Choose "From Text Box" or "From File". Supported file type is .txt</li>
<li>Click "Preview": Preview is useful to determine if you selected the correct separator or
if
you mistakenly included descriptors in your code import. For example, if you import a
file
with 15 codes separated by space, but you mistakenly selected a ; or | , your Code
Preview
will display as a single row and total codes: 1</li>
<li>Click "Validate": Validates and provides information about your code list you wish to
import. Removes duplicate codes, shows invalid/inactive codes. Code count difference
between
Code Preview and Code Validation can indicate issues in your code list. You must
validate
your codes and ensure you include only valid codes before the Import button will
activate.
</li>
<li>Click "Import"</li>
</ol>
<img class="figure-img img-fluid img-thumbnail" id="import" alt="import.png"
src="/vsac/support/authorguidelines/import.png"><br /><br />
ADD (+)
<ol type="a">
<li>Click the + in the Value Set Code List table</li>
<li>Type or paste your code in the yellow-highlighted row</li>
</ol>
<img class="figure-img img-fluid img-thumbnail" id="addnewcode" alt="addnewcode.png"
src="/vsac/support/authorguidelines/addnewcode.png"><br /><br />
</li>
<li>Click the <strong> Submit </strong> button to submit your value set to your steward for
approval.
Your steward will review your value set definition and decide to approve or reject the value set
definition.
<img class="figure-img img-fluid img-thumbnail" id="submittosteward" alt="submittosteward.png"

src="/vsac/support/authorguidelines/clickapprove.png">
</li>
</ol>
<p>When the steward approves the value set definition, your value set is in <strong> Ready to Publish
</strong> status. VSAC will publish a snapshot/temporary expansion of your definition version,
called
<strong>Latest</strong>, at midnight Eastern Time expanded/calculated using the most recent code
system
versions available in VSAC. VSAC will automatically publish subsequent 'Latest' expansions of your
value
set definition whenever code systems update in VSAC. If you require a specific type of expansion for
your value set, such as a static code list, or based on a later publication date, different code
system
version, or a pre-established expansion profile, go to the Expand/Publish tab to create a "Steward
Expansion."
</p>
<h4>Expand/Publish Value Set</h4>
<p>If you require non-default expansion settings, like a specific code system version (Setting A
Example),
or a date for expansion (Setting B Example) proceed to the Expansion/Publication sub tab after you
have
submitted, saved, and you or the steward has approved your value set definition. Make the selections
for
the non-default expansion settings as illustrated below.</p>

your
own OID is when you have an established pre-existing OID that you have published in another
context
external to VSAC and the OID is already used by the community, and the value set you create will
have the same content and purpose of the pre-existing OID.</li> </ul>
To manually enter your pre-existing OID, uncheck the Auto Generate box under the OID field,
and
follow the instructions in the tool tip<img alt="toolpitimage.jpg"

<li>If you need to enter an OID manually, the following rules apply:
<ul>
<li>OID Consists of all digits [1-9] or 0 if a single digit number, but no leading zeros
if
multiple digit number </li>
<li>Numbers may be separated by dots</li>
<li>NLM OID name space: Any OID entered MUST NOT start with 2.16.840.1.113 762.1.4</li>

which codes go into which clause.</li>
<li>If you know you need to use descriptors to find codes, you can either use "Search for
Codes"
(Method 2), as a simple and direct search and filter function, or you can use
<strong>Browse
Code Systems</strong> if you need to first study your terminologys hierarchy and
relationship details, and then select codes based on your discovery. Browse Code Systems
will open in a separate tab or window depending on your browser settings.

<li>Add your desired codes to your Code Clipboard (Add to Code Clipboard), or directly add
your

the more advanced Browse Code Systems. Your Code Clipboard is a temporary place for you
to
gather multiple codes to later include them in specific definition clauses. This
separate

<h4><a id="code">Code Clipboard</a></h4>
<p>Your Code Clipboard is a temporary place for you to gather multiple codes so you can later include
them
in specific definition clauses. Code Clipboard becomes especially important when you are gathering
several codes for multiple clauses as it gives you control over which codes you specify for your
clauses
within your value set definition. Code Clipboard is currently available to assist you with
intensional
value set definitions.</p>
<p>You can find your Code Clipboard in three places within the VSAC Authoring environment: the "Search
for
Codes" tab, "Browse Code Systems," and the "Advanced Code Editor."</p>
<h5>Search for Codes tab</h5>
<img class="figure-img img-fluid img-thumbnail" id="searchforcodes" alt="searchforcodes"
src="/vsac/support/authorguidelines/searchcode.png">
<p>Displays your gathered codes only from your currently selected code system.</p>
<p>You can gather more codes from the Search Code panel: select the checkboxes of codes you like and
then
click Add to Code Clipboard. You can also use the Import feature to import your own local text file
of
codes into your Code Clipboard.</p>
<p>Add to Clause: select the checkboxes of Code Clipboard codes you need for a specific clause, select
the
checkbox of that clause, and then click Add to Clause at the top of your Code Clipboard.</p>
<h5>Browse Code Systems</h5>
<img class="figure-img img-fluid img-thumbnail" id="browsecodesystems" alt="browsecodesystems"
src="/vsac/support/authorguidelines/browsecodesys.jpg">
<p>Displays all of your gathered codes from all code systems. Only those codes from the code system with
which you are currently working will be selectable; codes you have gathered previously from other
code
systems will be greyed out.</p>
<p>You can gather more codes from any of the Browse Code System panels: select the checkboxes of codes
you
like and then Add to Code Clipboard. You can also use the Import feature to import your own local
text
file of codes into your Code Clipboard.</p>
<p>Your Code Clipboard will persist when you switch back to your VSAC Authoring window, where you can
select
the checkboxes of codes you like, select the checkbox of your target clause, and then click Add to
Clause.</p>
<h5>Advanced Code Editor</h5>
<img class="figure-img img-fluid img-thumbnail" id="advcodeedit3" alt="advcodeedit3"
src="/vsac/support/authorguidelines/advcodeedit3.jpg">
<p>Use the Advanced Code Editor to add more codes to your clause.</p>
<p>Select the checkbox next to the clause for which you would like to add codes, and then select the
Advanced Code Editor button.</p>
<img class="figure-img img-fluid img-thumbnail" id="advcodeedit2" alt="advcodeedit2"
src="/vsac/support/authorguidelines/advcodeedit2.jpg">
<p>Displays your gathered codes only from your currently selected code system.</p>
<p>You can gather more codes from the Search Code panel within the Advanced Code Editor: select the
checkboxes of codes you like and then click Add to Code Clipboard.</p>
<p>You can select the checkboxes of any of your Code Clipboard codes and then click the centrally

<h4><a id="validoperators">Valid Operators for Each Code System</a></h4>
<p>This table displays the valid operators for each code system. The "all" operator can be used in just
a
few smaller code systems (CDCREC, CVX, HL7, HSLOC, NUCCPT, and SOP). Large code systems like SNOMED
CT,
CPT, etc. are either too large to use all codes or have copyright restrictions. Future development
will
include intensional value set authoring functionality for RxNorm and LOINC, as well as the ability
to
convert existing extensional value sets to logically defined intensional value sets as desired by
the
author.</p>

<h4>Add Metadata</h4>
<p><strong> Mandatory fields </strong>: OID, Name, Author, Steward, Purpose fields</p>
<h5>OID</h5>
<ul>
<li><strong>Object Identifier (OID) Assignment </strong> - we recommend the auto generate default
setting in which VSAC automatically generates an OID for your value set once you have entered
all
the information in the other fields, and have selected the "Save" button. If the automatic OID
assignment does not meet your purpose, you will need to to enter your own OID manually.</li>
<li><strong>Manual Entry of OID (Rare)</strong> - The only case in which you should manually enter
your
own OID is when you have an established pre-existing OID that you have published in another
context
external to VSAC and the OID is already used by the community, and the value set you create will
have the same content and purpose of the pre-existing OID.
<ul>
<li>To manually enter your pre-existing OID, uncheck the Auto Generate box under the OID
field,
and follow the instructions in the tool tip<img alt="toolpitimage.jpg"
src="/vsac/support/authorguidelines/tooltipimage.jpg" style="width: 20px;">to
correctly
enter your OID before selecting the Save button. </li>
<li>If you need to enter an OID manually, the following rules apply:
<ul>
<li>OID Consists of all digits [1-9] or 0 if a single digit number, but no leading
zeros
if multiple digit number </li>
<li>Numbers may be separated by dots</li>
<li>NLM OID name space: Any OID entered MUST NOT start with 2.16.840.1.113 762.1.4
