2025 ICD-10-CM code Z45.0
Encounter for adjustment and management of cardiac device.
Medical necessity for the use of Z45.0 must be supported by documentation that demonstrates the need for the adjustment or management of the cardiac device to maintain or improve the patient's health.
The physician or other qualified healthcare professional is responsible for the adjustment and management of the cardiac device, including evaluating its function, making necessary adjustments to its settings, and ensuring the patient's overall well-being related to the device.
- 21. Factors influencing health status and contact with health services (Z00-Z99)
- Z40-Z53 Encounters for other specific health care
In simple words: This code is used when you visit a doctor or other healthcare provider to have a heart device checked, adjusted, or managed. This includes having the device removed or replaced.
This code is used for encounters with the healthcare system for the adjustment and management of an implanted cardiac device.This includes removal or replacement of the device. It excludes malfunction or complication of the device, and fitting/adjustment of non-implanted devices.
Example 1: A patient with a pacemaker presents for a routine check-up to ensure the device is functioning correctly and the battery life is adequate. The physician interrogates the device and makes adjustments to the settings as needed., A patient with an implantable cardioverter-defibrillator (ICD) experiences an episode of ventricular fibrillation. The device successfully delivers a shock, and the patient is seen in the clinic the following day for device interrogation and adjustment of settings., A patient with a failing cardiac resynchronization therapy (CRT) device requires replacement of the device. The physician performs the procedure to remove the old device and implant a new one.
Documentation should include the type of cardiac device, the reason for the encounter (e.g., routine check, symptom evaluation, device malfunction), any adjustments made to the device settings, and any other relevant clinical information.
** This code should not be used for fitting and adjustment of non-implanted cardiac devices (e.g., external pacemakers, wearable cardioverter defibrillators).The Z45 category includes codes for other implanted device adjustments (e.g., nervous system, special senses), so it's important to use the most specific code available.
