Z45.018 — Encounter for adjustment and management of other part of cardiac pacemaker
Z45.018 is a billable, specific ICD-10-CM code for encounter for adjustment and management of other part of cardiac pacemaker. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- presence of other part of cardiac pacemaker (Z95.0)
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
Excludes1 inherited from the categories above Z45.018
These are not written on Z45.018, but they bind it: a note on a category applies to every code beneath it. Billing Z45.018 with anything listed here is a denial.
Written on Z45.01 — Encounter for adjustment and management of cardiac pacemaker
- encounter for adjustment and management of automatic implantable cardiac defibrillator with synchronous cardiac pacemaker (Z45.02)
Written on Z45 — Encounter for adjustment and management of implanted device
- malfunction or other complications of device - see Alphabetical Index
Excludes2 inherited from the categories above Z45.018
Also inherited, and the opposite of Excludes1: these conditions are not part of Z45.018, but a patient can have both, so you may code both.
Risk adjustment
Z45.018 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Medicare coverage
Z45.018 is named in 11 Medicare coverage policies — 11 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
