Z89: ICD10 Code for Acquired absence of limb

Acquired absence of limb (Z89) captures various health conditions, exposures, personal or family medical histories, statuses of implants or devices, and dependency on assistive technologies. These codes help document critical background factors that influence patient care, risk assessments, and ongoing management.

Symptoms

• Past medical conditions affecting current health (Z85-Z87)
• Family history of diseases affecting risk profiles (Z80-Z84)
• Chronic medication use and its management (Z79)
• Presence of implants, prosthetics, or devices (Z95-Z97)
• Dependency on dialysis, ventilators, or other enabling machines (Z99)
• Long-term allergy documentation for medication safety (Z88)
• Absence of limbs or organs from surgery or trauma (Z89-Z90)
• Post-surgical states requiring follow-up (Z98)
• Exposures to hazardous environments (Z77)

Diagnosis

These are not active diseases but recorded statuses, histories, or exposures. They are identified through medical history reviews, patient interviews, electronic health records, genetic counseling, medication reconciliation, and surgical follow-up assessments.

ICD10 Code Usage

The ICD10 code Z89 is used in chronic disease management plans, family history tracking, allergy alert systems, device tracking, post-procedure monitoring, insurance claims, and public health reporting to ensure holistic, personalized patient care planning.
