2022 ICD-10-CM Code Z45.0
Encounter for adjustment and management of cardiac device

Version 2022
ICD-10:Z45.0
Short Description:Encounter for adjustment and management of cardiac device
Long Description:Encounter for adjustment and management of cardiac device
Status: Not Valid for Submission

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)

Z45.0 is a non-specific and non-billable diagnosis 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 specific and is NOT valid for the year 2022 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding for Encounter for adjustment and management of cardiac device

Non-specific codes like Z45.0 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for encounter for adjustment and management of cardiac device:

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

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.
