New and Updated Sources (Expanded Representation Information) - 2015AA Release

General Information:

What's New for 2015AA

For 2015AA, there are 52 updated sources (including translation sources and one new subsource).

The new RXNORM subsource is MTHCMSFRF (Metathesaurus CMS Formulary Reference File). It represents drugs that may be included on Part D formularies. It is created and maintained by the Centers for Medicare and Medicaid Services (CMS).
For detailed information about sources that are new or have had changes made (e.g. new term types, new attribute names, etc.):

Source: Code on Dental Procedures and Nomenclature 2015
VSAB: CDT2015

New attribute name (ATN):
SOS

Discussion:
1. Previously, "Descriptor" values were made into definitions. They are now represented as "scope notes" by ATN = SOS
2. To create the hierarchy, the levels of the category, subcat, and subsubcat were used. The book version, however, does not display the codes in this order so the UMLS version of the hierarchy will be out of sync with the book in some places. The ADA is aware of this and has approved the method of using code ranges to create the hierarchy.

VSAB: CPT2015

New attribute name (ATN):
CITATION
CODING_TIP
PROPRIETARY_NAME
REPORTABLE

Discussion:
1. ATN = REPORTABLE has the valid values of 'T' or 'F' which indicate reportable codes. 'T' is for codes that can be used for the reporting of services while 'F' is used for codes that represent headings/subheadings and guidelines. Previously, this information was embedded in the TTY.
2. ATN = PROPRIETARY_NAME displays the proprietary name for multianalyte assays with algorithmic analyses contained in Appendix 0 of the CPT codebook.
3. A new value for ATN = CPT_LEVEL is 'ADM' and it represents the multianalyte assays with algorithmic analyses.

3. New attribute name (ATN):
HL7HI
HL7OAN

4. Dropped attribute name (ATN):
HL7AV
HL7RO
HL7SQ

Discussion:
1. ATN = HL7HI represents a history item.
2. ATN = HL7OAN represents 'Other annotation'.

3. Dropped attribute name (ATN):
EXTERNALLY_DEFINED_CODE_SYSTEM

Discussion:
1. RELA = has_count/count_of connects the LPN with an LN or LO.
2. ATN = EXTERNAL_COPYRIGHT_LINK is used for terms with an additional third party copyright. The field is populated with the COPYRIGHT_ID from the Source Organization table (Table 28c in the LOINC Manual).
3. ATN = SUBSEQUENT_TEXT_PROMPT indicates the text that should be displayed prompting further input from the user. For example, "Other, please specify."

Discussion:
1. New subsource: MTHCMSFRF_2014 (Metathesaurus CMS Formulary Reference File).
2. MTHFDA is included in each Metathesaurus release as part of RxNorm, however, it was not updated in this version. MTHFDA was last updated in 2011.
3. Selected portions of MSH and SNOMEDCT_US are included in the RxNorm release files, however, they are not processed as part of RxNorm for the Metathesaurus except in assigning RXCUI and RXAUI attributes.

New attribute name (ATN):
DEFAULT_LANGUAGECODE
EFFECTIVE_TIME

Discussion:
1. ATN = DEFAULT_LANGUAGECODE. This attribute is attached to the root concept. If an atom has a different language code, then the ATN = LANGUAGECODE would be created for the atom.
2. ATN = EFFECTIVE_TIME is created for concepts only.

2. Dropped attribute name (ATN):
LANGUAGECODE

Discussion:
ATN = DEFAULT_LANGUAGECODE. This attribute is attached to the root concept. If an atom has a different language code then the ATN = LANGUAGECODE would be created for the atom. In this version, there was no differing language code so the ATN = LANGUAGECODE was deprecated.

2. Dropped attribute name (ATN):
LANGUAGECODE


Discussion:
1. ATN = DEFAULT_LANGUAGECODE. This attribute is attached to the root concept. If an atom has a different language code then the ATN = LANGUAGECODE would be created for the atom. In this version, there was no differing language code so the ATN = LANGUAGECODE was deprecated.
2. ATN = DEFAULT_MODULE_ID. This attribute is attached to the root concept. If an atom has a different module id then the ATN = MODULE_ID would be created for that atom.
3. ATN = EFFECTIVE_TIME is created for concepts only.
4. SNOMEDCT_VET asserts some relationships between concepts from the SNOMEDCT core.
