Essential facts and insights about ICD-10 Coding for Nocturnal Hypoxia
Use ICD-10 code G47.36 for sleep-related hypoventilation in conditions classified elsewhere, ensuring proper documentation in clinical notes.
Additional codes that may be used with this diagnosis
Hypoxemia
Use for documenting supplemental oxygen requirement.
Morbid obesity
Use when obesity complicates the hypoxia.
Dependence on supplemental oxygen
Use when the patient requires long-term oxygen therapy.
The ICD-10 code for nocturnal hypoxia depends on the underlying cause. G47.36 is used for sleep-related hypoventilation due to other conditions, while G47.33 is used for obstructive sleep apnea with hypoxia.
Nocturnal hypoxia should be documented with specific SpO2 levels and duration from overnight oximetry, and any underlying conditions should be noted.
