Code Classification

  • Congenital malformations, deformations and chromosomal abnormalities
    (Q00-Q99)

      • Other osteochondrodysplasias

Q78.9 is a billable diagnosis code used to specify a medical diagnosis of osteochondrodysplasia, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

Unspecified diagnosis codes like Q78.9 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.
