2022 ICD-10-CM Code Z45.9
Encounter for adjustment and management of unspecified implanted device
Code Classification
Z45.9 is a billable diagnosis code used to specify a medical diagnosis of encounter for adjustment and management of unspecified implanted device. The code Z45.9 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
The code Z45.9 describes a circumstance which influences the patient's health status but not a current illness or injury. The code is unacceptable as a principal diagnosis.
Unspecified diagnosis codes like Z45.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
