CTD - Contact Data Segment

The CTD segment may identify any contact personnel associated with a patient referral message and its related transactions. The CTD segment will be paired with a PRD segment. The PRD segment contains data specifically focused on provider information in a referral. While it is important in an inter-enterprise transaction to transmit specific information regarding the providers involved (referring and referred-to), it may also be important to identify the contact personnel associated with the given provider. For example, a provider receiving a referral may need to know the office manager or the billing person at the institution of the provider who sent the referral. This segment allows for multiple contact personnel to be associated with a single provider.

CTD-1: Contact Role (CWE) 00196

Definition: This field contains the contact role that defines the relationship of the person described in this segment to the patient being referred. When a referral is inter-enterprise in nature, there are some important relationships that must be identified. For example, it may be necessary to identify the contact representative at the clinic that sent the referral. User-defined Table 0131 - Contact Role (in Chapter 3, "Patient Administration")is used as the HL7 identifier for the user-defined table of values for this field.

CTD-2: Contact Name (XPN) 01165

Definition: This field contains the name of the contact person identified in this segment. Generally, this field will describe a person or provider associated with the referral. If this contact name is a physician, you may refer to the CTD-7-Contact identifiers (section ) for the physician identifier.

CTD-3: Contact Address (XAD) 01166

Definition: This field contains the mailing address of the contact person identified in this segment. One of the key components for completing the "circle of care" and provider/institution bonding is the issuance of follow-up correspondence to the referring provider.

CTD-4: Contact Location (PL) 01167

Definition: This field contains the location of the contact, which is required when a contact that may be external to a given enterprise must be referenced. For example, if this contact represents the office manager of the referred-to physician, then the contact location should identify the clinic of the physician or provider to whom this referral has been sent. An application and facility identifier carried in the facility field specifies the identification of the contact's location. The application identifier and the facility identifier would be used in the same manner as their corresponding fields in the MSH segment (MSH-3-Sending application, MSH-5-Receiving application, MSH-4-Sending facility, MSH-6-Receiving facility). That is, the facility field will contain an application identifier and facility identifier which describe the location of this contact. However, it should be noted that they may describe a different location because the contact location being referenced in this field may not be the location from which the message originated, which is being described by the MSH.

CTD-5: Contact Communication Information (XTN) 01168

Definition: This field contains the information, such as the phone number or electronic mail address, used to communicate with the contact person or organization.

CTD-6: Preferred Method of Contact (CWE) 00684

Definition: This field contains the preferred method to use when communicating with the contact person. Refer to User-defined Table 0185 - Preferred Method of Contact in Chapter 2C, "Code Tables", for suggested values.

CTD-7: Contact Identifiers (PLN) 01171

Definition: This repeating field contains the contact's unique identifiers such as UPIN, Medicare and Medicaid numbers. Refer to User-defined Table 0338 - Practitioner ID Number Type (see Chapter 2, "Code Tables") for suggested values.
