Z96.4Presence of endocrine implants

Non-billable headerICD-10-CM

Z96.4 is a non-billable header ICD-10-CM code for presence of endocrine implants. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 inherited from the categories above Z96.4

Also inherited, and the opposite of Excludes1: these conditions are not part of Z96.4, but a patient can have both, so you may code both.

Written on Z96 Presence of other functional implants

  • complications of internal prosthetic devices, implants and grafts (T82-T85)
  • fitting and adjustment of prosthetic and other devices (Z44-Z46)

Other codes that can never be billed with Z96.4

These codes carry an Excludes1 note pointing at Z96.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z96.4 alone.

Risk adjustment

Z96.4 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.

Z96.4 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
