Potential Challenges
Restrictions on Standardization (e.g. proprietary code) Some codes, but not all, are linked to proprietary code standards that may require a license.
Restrictions on Use (e.g. licensing, user fees) Licensed Industry Standard Code Systems

This IG includes value set bindings to code systems that reference industry standard codes which require implementers to purchase a license before the coded concepts can be used. The following information summarizes the set of licensed Code Systems required by this IG and provides links to the information about where to go to obtain a license:

• AMA CPT: The CPT procedure and modifier codes are owned by the American Medical Association.
• X12: CARC (Claim Adjustment Reason Codes are owned by X12..
• NUBC: The NUBC secretariat is the American Hospital Association..
• NUCC: National Uniform Claim Committee (NUCC) is presently maintaining the Taxonomy code set. The codes are free and publically available for download and use. If the use however is “For commercial use, including sales or licensing, a license must be obtained”. It would be appropriate for an app developer to file the license form just like they would for any other code set; however, there is no fee.
• NCPDP: Retail Pharmacy data standards are defined by the NCPDP .
• 3M APR-DRG: AP-DRGs and APR-DRGs are owned by 3M. Use of AP-DRGs and APR-DRGs require a license.

Code Systems Not Requiring Licenses

This IG includes value set bindings to code systems that are industry standard codes available for use without licenses. The following information summarizes the set of Code Systems required by this IG that are available for use:

• ICD-CM Diagnosis Codes (ICD-10-CM): International Statistical Classification of Diseases and Related Health Problems (ICD). This IG will use version 10. The ICD-10-CM code set is maintained by the National Center for Health Statistics (NCHS) of the Centers for Disease Control and Prevention (CDC) for use in the United States. It is based on ICD-10, which was developed by the World Health Organization (WHO) and is used internationally a medical classification.
• ICD-Procedure Codes (ICD-PCS): The ICD-10-PCS code set is owned by CMS..
• DRGs.:MS-DRGs are owned by CMS. MS-DRGs are used for the Medicare population.
• HCPCS Level II Procedure and Modifier Codes: Primarily include non-physician products, supplies, and procedures not included in CPT. They are owned by CMS and are available for use.
• NDC (National Drug Codes): The US Federal Drug Administration (FDA) Data Standards Council assigns the first 5 digits of the 11 digit code..
• RARCCodes: The RARC codes are owned by CMS.
Privacy and Security Concerns This data, like any patient data should be exchanged securely. Current processes exist, governed by CMS and ONC, to securely transfer this data.
Estimate of Overall Burden The data elements in this class are already held by health care payers, anticipated burden of collection of data would be negligible. The CMS rule and Patient Access API already require CMS covered payers to share this data electronically. Many payers covered by the CMS rule have or are already considering making this data available in the same fashion for other lines of business.

CDC's Comment for draft USCDI v6

The integration of the "Medical Record Number" as a standardized data element in USCDI v6 is essential for bolstering public health efforts, particularly in the realm of immunization. As a unique identifier, it ensures that vaccination records are accurately matched to individual patients, which is crucial for effective immunization programs.

Standardizing the Medical Record Number enhances the ability of public health authorities to monitor immunization coverage, assess vaccine effectiveness, and identify pockets of under-vaccinated populations. This capability is especially important for coordinating responses to vaccine-preventable disease outbreaks and managing mass vaccination campaigns during pandemics.

Furthermore, precise patient matching enabled by a consistent Medical Record Number helps prevent duplicate immunization records and ensures that individuals receive vaccines according to recommended schedules. It also facilitates accurate reporting to immunization information systems (IIS), supporting real-time public health decision-making and resource allocation.

Inclusion of the "Medical Record Number" in USCDI v6 promises to significantly improve the accuracy of patient identification for immunizations, thereby enhancing public health surveillance capabilities and ensuring successful implementation of national immunization strategies. Urgent consideration for this inclusion is recommended to strengthen overall public health initiatives.

CSTE Comment - v6

CSTE supports inclusion of this data element in USCDI V6. Please see previously submitted CSTE comments for additional recommendations.

Submitted by Riki Merrick on

APHL points out that this is…

APHL points out that this is called out as one type of unique patient identifier in CLIA 42 CFR 493.1241(d) = "The patient's chart or medical record may be used as the test requisition or authorization but must be available to the laboratory at the time of testing and available to CMS or a CMS agent upon request." (https://www.ecfr.gov/current/title-42/part-493/section-493.1241#p-493.1241(d))
APHL supports the comment to elevate to the next version as submitted by CSTE in April 2024 "CSTE Comment - v5" (https://www.healthit.gov/isp/comment/13957) - this is a critical data element for matching records. APHL also recommends to include the assigning authority with ANY identifier data element (in all HL7 products this is part of the various supported identifier type data type). Thus we propose to update the definition to: "Alphanumeric value that uniquely identifies the patient's health record over time - at minimum within one organization, ideally at the national level), including a means to identify the organization or system that assigned it."
If ONC wants to support generic identifiers, then the elements should also include the identifier type Patient Identifier Type (https://www.healthit.gov/isp/taxonomy/term/3661/level-2), to be able to differentiate what is being shared.

Data element is captured, stored, or accessed in multiple production EHRs or other HIT modules from more than one developer.
Data element is electronically exchanged between more than two production EHRs or other HIT modules of different developers using available interoperability standards.

CSTE Comment - v5

CSTE requests the inclusion of medical record number, which is a very important data element for public health, in USCDI v5 in one of two ways. The preference would be to include it in the Patient Identifier data element, with the associated metadata elements required - which would be Type of patient identifier AND Assigning authority for patient identifier. Transmission of this information to public health in both case and laboratory reports is important for the following reasons:


1. It is incredibly helpful for person deduplication which currently requires a huge amount of manual effort at STLT public health agencies to manage the many potential duplicates (even with the best algorithms and automation for patient deduplication, often health department staff spend countless hours deduplicating partially matched patient records).
2. It is critical for identifying patients for follow-up - as in when medical information is sought as part of a case investigation or when additional demographics or contact information are needed in order to quickly reach a patient, or when lab results are needed from a hospital.
3. For any type of automated or semi-automated query of an HIE or another clinical repository (as will hopefully be possible through TEFCA), MR number will be invaluable in narrowing the query and ensuring the returned results pertain to the correct individual - this will save an enormous amount of time and frustration
4. For any bidirectional data exchange it would be invaluable to the receiving health care org to be able to use medical record to route the data to the correct medical record.


CSTE also recommends adding the two additional variables mentioned above to go with the identifier data element - one is the assigning authority (e.g., for a medical record it would be the name of the health care facility using the medical record system) and the other is the type of identifier (e.g., medical record, laboratory patient identifier, SSN, etc.)

CDC's comment on behalf of NACCHO for USCDI v5

Support - LHDs will also be able to use this to attribute encounter level information to a person-level, which is what is used for prevention analysis and program creation.
Having this element and the "identifier" element is going to be confusing for LHDs who will receive this data. There needs to be clarification made between the two and what their use cases are. Right now, they are not very clear in their submissions.

CDC's Consolidated Comment for USCDI v5

  • Including the "Medical Record Number" as a standardized data element in the v5 USCDI is a critical step toward ensuring precise and reliable patient identification within the healthcare system. Serving as a unique identifier, the Medical Record Number is a cornerstone for patient-centric care. It enables healthcare providers to accurately match patients with their health information across various points of care. This becomes increasingly significant in a complex and interconnected healthcare landscape, where patients often engage with multiple providers across different facilities and systems. By utilizing a standardized Medical Record Number as a common thread linking a patient's encounters and health data, healthcare providers are better positioned to access consolidated and comprehensive medical records. This, in turn, supports informed clinical decision-making based on a complete view of the patient's history, current conditions, and previous treatments. Moreover, the use of the Medical Record Number as a standardized identifier is instrumental in reducing errors related to patient identification—a critical factor in patient safety. Misidentification errors can lead to severe consequences, including incorrect diagnoses, inappropriate treatments, and unnecessary procedures, all of which are avoidable with precise identification methods. The implementation of the "Medical Record Number" in the USCDI v5 would mark a significant advancement towards a more integrated, efficient, and safe healthcare system. We strongly advocate for the inclusion of the "Medical Record Number" data element in the USCDI v5 due to its potential to fundamentally enhance patient identification processes, significantly reduce the occurrence of identification errors, and ensure that healthcare providers have immediate and reliable access to complete and consolidated patient medical records.
  • CSTE Comment: CSTE strongly agrees with CDC's recommendation for this data element.
