Provisional Codes in Value Sets
In response to the COVID-19 pandemic, VSAC has adapted to our users' needs for provisional codes that several standard terminologies are currently producing and frequently updating.The following standard terminologies (CPT®, ICD-10-CM, ICD-10-PCS, LOINC®, and SNOMED CT) have added provisional, pre-release codes in response to the COVID-19 pandemic, based on the most up to date information available at the time of their creation:
|Code System||VSAC Code System Version*||Additional Information|
|CPT||Provisional_2021-02-04||CPT COVID-19 coding and guidance|
|ICD-10-CM||Provisional_2020-12-19||New ICD-10-CM code for the 2019 Novel Coronavirus (COVID-19), Effective: 01/01/2021|
|ICD-10-PCS||Provisional_2020-10-19||2021 ICD-10-PCS COVID-19 UPDATE
In response to the COVID-19 public health emergency, the Centers for Medicare and Medicaid Services (CMS) is implementing 12 new procedure codes to describe the introduction or infusion of therapeutics into the International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS), effective August 01, 2020.
|LOINC||Provisional_2021-01-27||LOINC Prerelease Terms, Special Use Codes Only
A new version of LOINC (2.69) was released by Regenstrief in December, 2020. LOINC 2.69 includes Prerelease Terms created up through December 15, 2020. Any LOINC Prerelease Terms created by LOINC after December 15, 2020 will remain available in VSAC as provisional codes until the next version of LOINC is published in mid-2021, at which point the provisional codes will likely become official codes of the upcoming LOINC release.
|SNOMED CT||Provisional_2021-01-25||Pre-Release COVID-19 Related Content
These SNOMED CT COVID-19 pre-release codes will be available in the January 2021 International Edition of SNOMED CT International Edition. Because VSAC hosts only the SNOMED CT US Edition, and not the international edition, these pre-release, provisional codes will continue in VSAC as provisional codes until the SNOMED CT US Edition is published in March 2021, at which point the provisional codes will likely become official codes of the US Edition.
*The “VSAC Code System Version” designation is a VSAC-created element based on the VSAC acquisition date of the provisional codes. Each provisional code system version contains all provisional codes, cumulatively, until the terminology incorporates their provisional codes into a formal release.
Be aware that downstream users may not be ready to handle prerelease codes until they are published in an official terminology release.
How to Include Provisional Codes in Your Value Set
VSAC now includes provisional code system versions within the “Most Recent Code System Versions in VSAC” default expansion profile calculation. You no longer need to perform a special Expand/Publish step when you create value sets that include provisional codes.
You must click Approve to produce your automatically updating “Latest” published value set expansion for your users.
The major benefit to this method is that you can use the value set’s “Latest” URL on web pages. This “Latest” URL will always be constant so you will not have to update the URL on your web pages when you update your value set.
Linking to the “Latest” expansion URL on your web pages will ensure that your users always connect to your correct value set expansion (code list) as the terminologies update and promote their provisional codes to official codes in official version releases. Here is an example of a “Latest” expansion URL: https://vsac.nlm.nih.gov/valueset/2.16.840.1.1137126.96.36.1994.9/expansion/Latest
