F89 is a billable diagnosis code used to specify a medical diagnosis of unspecified disorder of psychological development. The code F89 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code F89 might also be used to specify conditions or terms like achondrogenesis, achondroplasia, developmental disorder, developmental hereditary disorder, developmental mental disorder , developmentally disabled, etc.

Unspecified diagnosis codes like F89 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.
