Apnea, not elsewhere classified

This code represents a temporary cessation of breathing that is not due to sleep-related disorders or conditions specific to newborns. It indicates an episode where an individual stops breathing for a period, and the underlying cause is not otherwise specified or classifiable to a more specific diagnosis.

Use this code when documentation indicates episodes of apnea in an adult or child, and the physician has ruled out sleep apnea and newborn-specific apnea. This code is appropriate when the cause of the apnea is unknown or attributed to a condition not elsewhere classified. Supporting documentation should clearly state "apnea, not otherwise specified" or similar.

• Ensure documentation explicitly excludes sleep apnea (G47.3-) and newborn apnea (P28.4-, P28.3-).
• Avoid using this code if a more specific cause for the apnea is identified; always code to the highest level of specificity.
• This code is often used as a symptom code; look for an underlying condition that may be causing the apnea and code it as the primary diagnosis if applicable.
