Q80.9 is a billable diagnosis code used to specify a medical diagnosis of congenital ichthyosis, unspecified. The code Q80.9 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 Q80.9 might also be used to specify conditions or terms like autosomal dominant mutilating keratoderma, bathing suit ichthyosis, cednik syndrome, congenital biliary atresia, congenital cataract ichthyosis syndrome , congenital deformity of foot and ankle, etc. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
Unspecified diagnosis codes like Q80.9 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.
