ICD-10-CM Code Z45.0

Encounter for adjustment and management of cardiac device

Version 2020 Non-Billable Code

Not Valid for Submission

Z45.0 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of encounter for adjustment and management of cardiac device. The code is NOT valid for the year 2020 for the submission of HIPAA-covered transactions.

ICD-10:Z45.0
Short Description:Encounter for adjustment and management of cardiac device
Long Description:Encounter for adjustment and management of cardiac device

Consider the following ICD-10 codes with a higher level of specificity:

  • Z45.01 - Encounter for adjustment and management of cardiac pacemaker
  • Z45.010 - Encounter for checking and testing of cardiac pacemaker pulse generator [battery]
  • Z45.018 - Encounter for adjustment and management of other part of cardiac pacemaker
  • Z45.02 - Encounter for adjustment and management of automatic implantable cardiac defibrillator
  • Z45.09 - Encounter for adjustment and management of other cardiac device

Code Classification

  • Factors influencing health status and contact with health services (Z00–Z99)
    • Encounters for other specific health care (Z40-Z53)
      • Encounter for adjustment and management of implanted device (Z45)

Information for Patients


Pacemakers and Implantable Defibrillators

An arrhythmia is any disorder of your heart rate or rhythm. It means that your heart beats too quickly, too slowly, or with an irregular pattern. Most arrhythmias result from problems in the electrical system of the heart. If your arrhythmia is serious, you may need a cardiac pacemaker or an implantable cardioverter defibrillator (ICD). They are devices that are implanted in your chest or abdomen.

A pacemaker helps control abnormal heart rhythms. It uses electrical pulses to prompt the heart to beat at a normal rate. It can speed up a slow heart rhythm, control a fast heart rhythm, and coordinate the chambers of the heart.

An ICD monitors heart rhythms. If it senses dangerous rhythms, it delivers shocks. This treatment is called defibrillation. An ICD can help control life-threatening arrhythmias, especially those that can cause sudden cardiac arrest (SCA). Most new ICDs can act as both a pacemaker and a defibrillator. Many ICDs also record the heart's electrical patterns when there is an abnormal heartbeat. This can help the doctor plan future treatment.

Getting a pacemaker or ICD requires minor surgery. You usually need to stay in the hospital for a day or two, so your doctor can make sure that the device is working well. You will probably be back to your normal activities within a few days.
