| Code | Display | Definition |
| connectivity-status | Connectivity status | The overall system connectivity status as calculated by the CIED manufacturer. |
| connectivity-modifier | Connectivity modifier | Additional modifiers to connectivity status as calculated by the CIED manufacturer. |
| setup-not-completed | Setup not completed | Device/monitor setup has not been completed. E.g. pending initial setup or there is no device/monitor association. |
| not-applicable | N/A | Connectivity states are not applicable for this device. E.g. device is not compatible with remote monitoring or requires patient initiated interrogations. |
| connected | Connected | Communication has been successful within the expected time period. |
| disconnected | Disconnected | Communication has not occurred within the expected time period. |
| suspended | Suspended | Patient has been temporarily removed from the disconnected state. This is not intended to be an actionable status. |
| inactive | Inactive | Patient has been permanently removed from the disconnected status. |
| unenrolled | Unenrolled | Patient has been unenrolled from remote monitoring or remote monitoring has been discontinued. |
| transferred | Transferred | The patient has been transferred to another remote monitoring clinic. |
| last-cied-connectivity-time | Last CIED to monitor communication | The timestamp of the most recent communication between the CIED and monitor. |
| last-monitor-connectivity-time | Last monitor to remote monitoring software communication | The timestamp of the most recent communication from the monitor to the remote monitoring platform. |
| next-cied-connectivity-date | Next CIED to monitor communication | The timestamp of the next expected communication between the CIED and monitor. |
| next-monitor-connectivity-date | Next monitor to remote monitoring software communication | The timestamp of the next expected communication from the monitor to the remote monitoring platform. |
| last-interrogation-date | Last remote device interrogation date | The date of the most recent remote device interrogation with a personal monitor. |
| next-interrogation-date | Next scheduled remote device interrogation date | The date of the next scheduled remote device interrogation. |
| next-secondary-interrogation-date | Next scheduled remote device interrogation date, secondary clinic | The date of the next scheduled remote device interrogation by the secondary clinic for patients who are dual-managed. |
| observation-cied-connectivity | CIED connectivity | FHIR observation constrained to the CardX CIED connectivity profile. |
| bedside-device | Bedside Monitor | Standalone device, not intended to provide monitoring while on the go. |
| mobile-monitor | Mobile App | App based monitor. |
| portable-device | Portable Device | Standalone device, with battery capacity to provide monitoring while on the go. |
| connection-interval | Connection interval | The time interval in days between expected CIED and remote monitoring software communication. |
| expected-time-period | Expected time period | The time period in days in which successful communication must take place for the connectivity status to remain connected. |
| status-reason | Status reason | Text describing reasons why the patient may be listed at a given status and/or modifier. |
| status-guidance | Status guidance | Text describing steps to get the patient to a connected status. |
| idco-pid | Identifier used in IDCO PID HL7 Segment | IDCO specifies a combination of model and serial number as model:model-number/serial:serial-number |
