Data Field Changes

Data Field Changes

May 12, 2011

adt interface progress
ADT Interface Progress
  • Decision to provide data to downstream partners in the current HealthQuest format where appropriate
  • Met with the 37 downstream applications customers for confirmation of the current data mapping
  • Worked with the HL7 Standards Committee to discuss field changes

• Pathology

• Radiology

• Pharmacy


• Carelink

  • Met with the downstream applications customers to document application requirements and issues
  • Additional meetings to resolve issues, as necessary
  • Almost completed initial round of unit testing
outstanding work
Outstanding Work

Work to be completed:

  • Completion of unit testing by August 1, 2011
  • Completion of category lists (i.e., Field Values)
  • Integrated testing


  • Process for transferring HealthQuest Location data to downstream applications
  • MRN SCD (Self Check Digit)
  • Physician Address Sequence Number
  • Some fields will not be available from the HL7 interface (will be available using an extract or reporting): Attachment 1
    • Smoker’s Flag
  • Some fields will not be available at all: Attachment 1
field discussion
Field Discussion

MiChart has many new field names, most are related to HealthQuest field names, but the size, format and function may differ greatly. Few of the key fields discussed below convert directly, between MiChart and HealthQuest.

Key fields include the following:

Application Name - Michart HealthQuest


Contact Service Number (CSN) Visit number

Patient Class Patient Type

Patient Type Several Fields

Department ID/Unit Location or Resource ID /Unit

Service Codes Service Codes

key data fields mrn csn
Key Data Fields - MRN - CSN


The MiChart application will implement Epic’s recommendation of using the Medical Record Number (MRN) to identify the patient. The MRN will be assigned in the same manner as the CPI/ MRN are currently assigned in HealthQuest. The MiChart MRN will replace the CPI as the Patient Identifier. MiChart will use all 9 digits and will start the number at ‘100,000,000’. Patient demographics in HealthQuest will be loaded into MiChart and the CPI numbers will turn into their MRN number.

MiChart MRN HealthQuest CPI

100000000 010000000

CSN – Visit +Date or Service (EWS used Appointment number)

The Contact Serial Number (CSN) will be a numerical sequential number that is unique for every encounter, appointment, visit, or admission for every patient in MiChart. It will replace the ‘cpi+ visit’ as a unique identifier for patient care. This number will be up to 10 digits long and will start at ‘10000’. We have over 1.5 million appointments a year and will reach 7 digits within the first year of implementation. Since the CSN is a unique number and is assigned at the encounter level we will have the highest level of granularity. This will improve our ability to tie back directly to the patient for any encounter/visit record such as order, result, charge or document. For the most part, the CSN will be used when submitting Charges.

Downstream applications will receive the CSN in place of the Visit Number

key data fields har department id
Key Data Fields – HAR – Department ID

HAR – Account Number (CPI+ Visit)

The Hospital Account Record (HAR) is a unique number that is assigned based on Hospital Billing Rules. Since the HAR is a unique number it gives us the flexibility of attaching Multiple CSN’s based on the needs of Hospital Billing. This method separates Patient Care from Billing while providing us the highest level of granularity. This will increase our ability to provide the best patient care without compromising our billing. The HAR won’t be used in patient care.

Downstream applications will receive the HAR in place of the Account Number

MiChart HAR HealthQuest Account Number

100000000123456789 1000

Department ID – Location (Outpatient)/Unit (Inpatient)

Department ID in MiChart is the HealthQuest Location or the EWS Resource ID. It has been expanded to be more descriptive of the location and more beneficial for reporting.

key data fields patient class patient type
Key Data Fields - Patient Class – Patient Type

Patient Class – Patient Type

Patient Class is a billing tool in MiChart. It is used primarily to support billing and suggest the correct HAR

Downstream applications will receive the HealthQuest Patient Type (e.g., I, O , G, E)

Patient Type – Patient Class + VIP+ Destination Program + Confidential + Corporate Level User Codes

Patient Type indicates a special patient characterization, such as Employee or Anonymous. It can also be used to drive confidentiality. UMHS will also use Patient Type to identify our Destination Program patients.
