Nasal congestion

This code identifies the symptom of nasal congestion, commonly known as a stuffy or blocked nose. It indicates an obstruction of the nasal passages due to swollen membranes, excess mucus, or other factors, making breathing difficult through the nose.

Use this code when documentation explicitly states "nasal congestion" as a presenting symptom without a more specific underlying diagnosis established at the time of encounter. It is appropriate for acute or chronic nasal blockage where the etiology is not yet determined or is not the primary focus of the visit.

• Do not code this as a primary diagnosis if a definitive cause (e.g., acute sinusitis, allergic rhinitis) is documented.
• Consider sequencing this code after a more definitive diagnosis if the congestion is a symptom of that condition.
• Ensure documentation clearly states "nasal congestion" or "stuffy nose"; avoid inferring from general respiratory symptoms.
