Modifiers may apply depending on circumstances, such as the use of oxygen conserving devices (e.g., modifier QH).
Medical necessity for code E0434 is established by documented evidence of hypoxemia (low blood oxygen levels) and the clinical need for supplemental oxygen therapy to alleviate symptoms and improve the patient's quality of life. This may involve a physician's clinical judgment, and supporting documentation such as pulse oximetry or ABG results.
The clinical responsibility lies with the physician or other qualified healthcare provider who orders and monitors the patient's use of the portable liquid oxygen system.
