Valid for Submission
Z05.9 is a billable diagnosis code used to specify a medical diagnosis of observation and evaluation of newborn for unspecified suspected condition ruled out. The code Z05.9 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code Z05.9 might also be used to specify conditions or terms like probable sars or suspected clinical finding. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
The code Z05.9 is applicable to newborn patients only. It is clinically and virtually impossible to use this code on a non-newborn patient.
Unspecified diagnosis codes like Z05.9 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.
