Z89Acquired absence of limb

Non-billable headerICD-10-CM

Z89 is a non-billable header ICD-10-CM code for acquired absence of limb. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • acquired deformities of limbs (M20-M21)
  • congenital absence of limbs (Q71-Q73)

Includes

Conditions this code covers.

  • amputation status
  • postprocedural loss of limb
  • post-traumatic loss of limb

Other codes that can never be billed with Z89

These codes carry an Excludes1 note pointing at Z89. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z89 alone.

  • M20Acquired deformities of fingers and toes
  • M21Other acquired deformities of limbs
  • Z47.31Aftercare following explantation of shoulder joint prosthesis
  • Z47.32Aftercare following explantation of hip joint prosthesis
  • Z47.33Aftercare following explantation of knee joint prosthesis

Risk adjustment

Z89 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.

Code to one of these instead Z89

7 child codes. Green means billable.
