  DENEX	denominator exclusions	Patients who should be removed from the eMeasure population and denominator before determining if numerator criteria are met. Denominator exclusions are used in proportion and ratio measures to help narrow the denominator.
  DENEXCEP	denominator exceptions	Denominator exceptions are those conditions that should remove a patient, procedure or unit of measurement from the denominator only if the numerator criteria are not met. Denominator exceptions allow for adjustment of the calculated score for those providers with higher risk populations. Denominator exceptions are used only in proportion eMeasures. They are not appropriate for ratio or continuous variable eMeasures. Denominator exceptions allow for the exercise of clinical judgment and should be specifically defined where capturing the information in a structured manner fits the clinical workflow. Generic denominator exception reasons used in proportion eMeasures fall into three general categories: * Medical reasons * Patient reasons * System reasons
  DENOM	denominator	It can be the same as the initial patient population or a subset of the initial patient population to further constrain the population for the purpose of the eMeasure. Different measures within an eMeasure set may have different Denominators. Continuous Variable eMeasures do not have a Denominator, but instead define a Measure Population.
  IPP	initial patient population	The initial patient population refers to all patients to be evaluated by a specific quality measure who share a common set of specified characteristics within a specific measurement set to which a given measure belongs. Details often include information based upon specific age groups, diagnoses, diagnostic and procedure codes, and enrollment periods.
  IP	initial population	The initial population refers to all entities to be evaluated by a specific quality measure who share a common set of specified characteristics within a specific measurement set to which a given measure belongs.
  MSRPOPL	measure population	Measure population is used only in continuous variable eMeasures. It is a narrative description of the eMeasure population. (e.g., all patients seen in the Emergency Department during the measurement period).
  NUMER	numerator	Numerators are used in proportion and ratio eMeasures. In proportion measures the numerator criteria are the processes or outcomes expected for each patient, procedure, or other unit of measurement defined in the denominator. In ratio measures the numerator is related, but not directly derived from the denominator (e.g., a numerator listing the number of central line blood stream infections and a denominator indicating the days per thousand of central line usage in a specific time period).
  NUMEX	numerator exclusions	Numerator Exclusions are used only in ratio eMeasures to define instances that should not be included in the numerator data. (e.g., if the number of central line blood stream infections per 1000 catheter days were to exclude infections with a specific bacterium, that bacterium would be listed as a numerator exclusion.)

  MASKED	masked	Security metadata observation value conveying the alteration integrity of an IT resource (data, information object, service, or system capability) by indicating the mechanism by which software systems can make data unintelligible (that is, as unreadable and unusable by algorithmically transforming plaintext into ciphertext) such that it can only be accessed or used by authorized users. An authorized user may be provided a key to decrypt per license or "shared secret". *Usage Note:* "MASKED" may be used, per applicable policy, as a flag to indicate to a user or receiver that some portion of an IT resource has been further encrypted, and may be accessed only by an authorized user or receiver to which a decryption key is provided.
  PSEUDED	pseudonymized	Security metadata observation value conveying the alteration integrity of an IT resource (data, information object, service, or system capability), by indicating the mechanism by which software systems can strip portions of the resource that could allow the identification of the source of the information or the information subject. Custodian may retain a key to relink data necessary to reidentify the information subject. *Rationale:* Personal data which has been processed to make it impossible to know whose data it is. Used particularly for secondary use of health data. In some cases, it may be possible for authorized individuals to restore the identity of the individual, e.g.,for public health case management. Based on ISO/TS 25237:2008 Health informatics-Pseudonymization
  REDACTED	redacted	Security metadata observation value used to indicate the mechanism by which software systems can filter an IT resource (data, information object, service, or system capability) to remove any portion of the resource that is not authorized to be access, used, or disclosed. *Usage Note:* "REDACTED" may be used, per applicable policy, as a flag to indicate to a user or receiver that some portion of an IT resource has filtered and not included in the content accessed or received.
  SUBSETTED	subsetted	Metadata observation used to indicate that some information has been removed from the source object when the view this object contains was constructed because of configuration options when the view was created.

  VERSIONED	versioned	Security metadata observation value conveying the alteration integrity of an IT resource (data, information object, service, or system capability) which indicates that the resource only retains versions of an IT resource for access and use per applicable policy *Usage Note:* When this code is used, expectation is that the system has removed historical versions of the data that falls outside the time period deemed to be the effective time of the applicable version.
  CRYTOHASH	cryptographic hash function	Security metadata observation value used to indicate the mechanism by which software systems can establish that data was not modified in transit. *Rationale:* This definition is intended to align with the ISO 22600-2 3.3.19 definition of cryptographic checkvalue: Information which is derived by performing a cryptographic transformation (see cryptography) on the data unit. The derivation of the checkvalue may be performed in one or more steps and is a result of a mathematical function of the key and a data unit. It is usually used to check the integrity of a data unit. **Examples:** * SHA-1 * SHA-2 (Secure Hash Algorithm)
  DIGSIG	digital signature	Security metadata observation value used to indicate the mechanism by which software systems use digital signature to establish that data has not been modified. *Rationale:* This definition is intended to align with the ISO 22600-2 3.3.26 definition of digital signature: Data appended to, or a cryptographic transformation (see cryptography) of, a data unit that allows a recipient of the data unit to prove the source and integrity of the data unit and protect against forgery e.g., by the recipient.

A particular Certificate Policy might indicate the applicability of a type of certificate to the authentication of electronic data interchange transactions for the trading of goods within a given price range. Another example is Cross Certification with Federal Bridge.
  LOAAN1	low authentication level of assurance	Indicator of low digital quality or reliability of the digital reliability of the verification and validation process used to verify the claimed identity of an entity by securely associating an identifier and its authenticator. \[Based on ISO 7498-2\] The degree of confidence in the vetting process used to establish the identity of the individual to whom the credential was issued, and 2) the degree of confidence that the individual who uses the credential is the individual to whom the credential was issued. \[OMB M-04-04 E-Authentication Guidance for Federal Agencies\] Low authentication level of assurance indicates that the relying party may have little or no confidence in the asserted identity's validity. Level 1 requires little or no confidence in the asserted identity. No identity proofing is required at this level, but the authentication mechanism should provide some assurance that the same claimant is accessing the protected transaction or data. A wide range of available authentication technologies can be employed and any of the token methods of Levels 2, 3, or 4, including Personal Identification Numbers (PINs), may be used. To be authenticated, the claimant must prove control of the token through a secure authentication protocol. At Level 1, long-term shared authentication secrets may be revealed to verifiers. Assertions issued about claimants as a result of a successful authentication are either cryptographically authenticated by relying parties (using approved methods) or are obtained directly from a trusted party via a secure authentication protocol. \[Summary of the technical requirements specified in NIST SP 800-63 for the four levels of assurance defined by the December 2003, the Office of Management and Budget (OMB) issued Memorandum M-04-04, E-Authentication Guidance for Federal Agencies.\]
  LOAAN2	basic authentication level of assurance	Indicator of basic digital quality or reliability of the digital reliability of the verification and validation process used to verify the claimed identity of an entity by securely associating an identifier and its authenticator. \[Based on ISO 7498-2\] The degree of confidence in the vetting process used to establish the identity of the individual to whom the credential was issued, and 2) the degree of confidence that the individual who uses the credential is the individual to whom the credential was issued. \[OMB M-04-04 E-Authentication Guidance for Federal Agencies\] Basic authentication level of assurance indicates that the relying party may have some confidence in the asserted identity's validity. Level 2 requires confidence that the asserted identity is accurate. Level 2 provides for single-factor remote network authentication, including identity-proofing requirements for presentation of identifying materials or information. A wide range of available authentication technologies can be employed, including any of the token methods of Levels 3 or 4, as well as passwords. Successful authentication requires that the claimant prove through a secure authentication protocol that the claimant controls the token. Eavesdropper, replay, and online guessing attacks are prevented. Long-term shared authentication secrets, if used, are never revealed to any party except the claimant and verifiers operated by the CSP; however, session (temporary) shared secrets may be provided to independent verifiers by the CSP. Approved cryptographic techniques are required. Assertions issued about claimants as a result of a successful authentication are either cryptographically authenticated by relying parties (using approved methods) or are obtained directly from a trusted party via a secure authentication protocol. \[Summary of the technical requirements specified in NIST SP 800-63 for the four levels of assurance defined by the December 2003, the Office of Management and Budget (OMB) issued Memorandum M-04-04, E-Authentication Guidance for Federal Agencies.\]
  LOAAN3	medium authentication level of assurance	Indicator of medium digital quality or reliability of the digital reliability of verification and validation of the process used to verify the claimed identity of an entity by securely associating an identifier and its authenticator. \[Based on ISO 7498-2\] The degree of confidence in the vetting process used to establish the identity of the individual to whom the credential was issued, and 2) the degree of confidence that the individual who uses the credential is the individual to whom the credential was issued. \[OMB M-04-04 E-Authentication Guidance for Federal Agencies\] Medium authentication level of assurance indicates that the relying party may have high confidence in the asserted identity's validity. Level 3 is appropriate for transactions that need high confidence in the accuracy of the asserted identity. Level 3 provides multifactor remote network authentication. At this level, identity-proofing procedures require verification of identifying materials and information. Authentication is based on proof of possession of a key or password through a cryptographic protocol. Cryptographic strength mechanisms should protect the primary authentication token (a cryptographic key) against compromise by the protocol threats, including eavesdropper, replay, online guessing, verifier impersonation, and man-in-the-middle attacks. A minimum of two authentication factors is required. Three kinds of tokens may be used: * "soft" cryptographic token, which has the key stored on a general-purpose computer, * "hard" cryptographic token, which has the key stored on a special hardware device, and * "one-time password" device token, which has symmetric key stored on a personal hardware device that is a cryptographic module validated at FIPS 140-2 Level 1 or higher. Validation testing of cryptographic modules and algorithms for conformance to Federal Information Processing Standard (FIPS) 140-2, Security Requirements for Cryptographic Modules, is managed by NIST. Authentication requires that the claimant prove control of the token through a secure authentication protocol. The token must be unlocked with a password or biometric representation, or a password must be used in a secure authentication protocol, to establish two-factor authentication. Long-term shared authentication secrets, if used, are never revealed to any party except the claimant and verifiers operated directly by the CSP; however, session (temporary) shared secrets may be provided to independent verifiers by the CSP. Approved cryptographic techniques are used for all operations. Assertions issued about claimants as a result of a successful authentication are either cryptographically authenticated by relying parties (using approved methods) or are obtained directly from a trusted party via a secure authentication protocol. \[Summary of the technical requirements specified in NIST SP 800-63 for the four levels of assurance defined by the December 2003, the Office of Management and Budget (OMB) issued Memorandum M-04-04, E-Authentication Guidance for Federal Agencies.\]
  LOAAN4	high authentication level of assurance	Indicator of high digital quality or reliability of the digital reliability of the verification and validation process used to verify the claimed identity of an entity by securely associating an identifier and its authenticator. \[Based on ISO 7498-2\] The degree of confidence in the vetting process used to establish the identity of the individual to whom the credential was issued, and 2) the degree of confidence that the individual who uses the credential is the individual to whom the credential was issued. \[OMB M-04-04 E-Authentication Guidance for Federal Agencies\] High authentication level of assurance indicates that the relying party may have very high confidence in the asserted identity's validity. Level 4 is for transactions that need very high confidence in the accuracy of the asserted identity. Level 4 provides the highest practical assurance of remote network authentication. Authentication is based on proof of possession of a key through a cryptographic protocol. This level is similar to Level 3 except that only “hard� cryptographic tokens are allowed, cryptographic module validation requirements are strengthened, and subsequent critical data transfers must be authenticated via a key that is bound to the authentication process. The token should be a hardware cryptographic module validated at FIPS 140-2 Level 2 or higher overall with at least FIPS 140-2 Level 3 physical security. This level requires a physical token, which cannot readily be copied, and operator authentication at Level 2 and higher, and ensures good, two-factor remote authentication. Level 4 requires strong cryptographic authentication of all parties and all sensitive data transfers between the parties. Either public key or symmetric key technology may be used. Authentication requires that the claimant prove through a secure authentication protocol that the claimant controls the token. Eavesdropper, replay, online guessing, verifier impersonation, and man-in-the-middle attacks are prevented. Long-term shared authentication secrets, if used, are never revealed to any party except the claimant and verifiers operated directly by the CSP; however, session (temporary) shared secrets may be provided to independent verifiers by the CSP. Strong approved cryptographic techniques are used for all operations. All sensitive data transfers are cryptographically authenticated using keys bound to the authentication process. \[Summary of the technical requirements specified in NIST SP 800-63 for the four levels of assurance defined by the December 2003, the Office of Management and Budget (OMB) issued Memorandum M-04-04, E-Authentication Guidance for Federal Agencies.\]
  LOAAP1	low authentication process level of assurance	Indicator of the low digital quality or reliability of a defined sequence of messages between a Claimant and a Verifier that demonstrates that the Claimant has possession and control of a valid token to establish his/her identity, and optionally, demonstrates to the Claimant that he or she is communicating with the intended Verifier. \[Based on NIST SP 800-63-2\] Low authentication process level of assurance indicates that (1) long-term shared authentication secrets may be revealed to verifiers; and (2) assertions and assertion references require protection from manufacture/modification and reuse attacks. \[Summary of the technical requirements specified in NIST SP 800-63 for the four levels of assurance defined by the December 2003, the Office of Management and Budget (OMB) issued Memorandum M-04-04, E-Authentication Guidance for Federal Agencies.\]
