Code System InformationLink
Notes"The Clinical Care Classification (CCC) System is a free empirically developed system consisting of two parts:
  • Standardized coded nursing terminology
  • Information model designed for the electronic documentation of clinical nursing practice

CCC supports the electronic capture of discrete patient care concepts (data elements) that measure the relationship of the data to outcomes by documenting the “essence of care.” The CCC System is designed for storing, processing, retrieving and analyzing nursing and allied health professionals’ data in electronic health records (EHR) systems for reuse, summary, aggregation, warehousing, big data uses and evidence-based guidelines. The CCC System (see Framework for details) consists of a four-level framework/hierarchy that allows data to be statistically aggregated upward or parsed downward to the smallest atomic-level data element:

  • 1st level: Four healthcare patterns
  • 2nd level: 21 care components (classes)
  • 3rd level: Nursing terminologies
  • 176 nursing diagnoses
  • 804 nursing interventions/actions
  • 528 nursing outcomes
  • 4th level: Three outcome qualifiers and four action type qualifiers. The terminologies are classified by 21 care components to form a single interrelated system that provides the framework that links the diagnoses to interventions, to outcomes and to each other, as well as map their concepts to other health-related terminologies: SNOMED-CT, LOINC, ICNP, ICD-10, etc.

The CCC System terminological concepts use a five alpha-numeric character code for information exchange and interoperability that is similar to International Statistical Classification of Diseases and Health-Related Problems (ICD-10) (WHO, 1990). The coding is used to track patient care for the entire episode of illness and measure care over time, in all healthcare settings, population groups and/or geographic locations."

  1. There is an error here.    This was originally registered as hhcc by Suzanne Bakken over 20 years ago, but has been superseded.  The documentation of this change is: 

    Home HealthCare Classification System codes.

    Note that this code system has been retired, and has been replaced by 2.16.840.1.113883.6.236 CCC.

    This change was done (also by Ms. Bakken) on 2011-09-30 14:01:44.0, and the information (matching what is on this page, for the most part) is metadata associated with the OID value 2.16.840.1.113883.6.236 - please update this page accordingly.

  2. Julie James, can we get this topic added to our agenda for next week's meeting on 6/10/2020

    • The correct OID for CCC should be the one in the table - that may have been my mistake but am clarifying with the developers.
    • The administration for CCC has been moved to Hospital Corporations of America under Jane Englebright.
    • I've sent both Virginia and Jane an email to review the above table and update as needed.

    Let me know if you have any other questions.  Thanks...Susan

  3. Susan, please go to the HL7 OID registry and put the above OID into the search field on the left and do a Find OID.  Then also search for OID  2.16.840.1.113883.6.236 there.   According to the information published there, on September 30, 2011 Sue Bakken created a new OID superseding 2.16.840.1.113883.6.17, and stated in the Harmonization meetings at that time (I can dig up the minutes if we want to dig that deeply) that old one was being retired and replaced, as the changes between the versions were larger than those accommodated by the versioning policy for HL7 code systems with HL7 maintained identifiers (such as the change from SNOMED RT to SNOMED CT, different code system OIDs; same with ICD9 vs ICD10 vs. ICD11)  The OID 2.16.840.1.113883.6.236 has been published in the HL7 V3 Normative Editions for CCC since that time - every year.     This is the basis for my assertion above that the OID 2.16.840.1.113883.6.17 in the table is incorrect.  The history and full documentation is in both of these entries in the HL7 OID registry.

  4. Update URI to be consistent with THO. Updated OID after confirming the information Ted provided in his June 8th comment.
