What Is Sleep disorder not due to a substance or known physiological condition?
Sleep disorder not due to a substance or known physiological condition—coded clinically as F51.9 across Sleep Disorders guidelines—combines iron/thyroid screening [Sleep disorder not due to a substance or known physiological condition F51.9] with structured follow-up of Apnea-Hypopnea Index (AHI) [Sleep disorder not due to a substance or known physiological condition F51.9] (< 5 events/hour (F51.9)).
