Dysphagia, pharyngoesophageal phase

This code signifies difficulty swallowing specifically originating from the pharynx and upper esophageal sphincter. It indicates a problem with the initial stages of food transit from the mouth into the esophagus, often involving impaired muscle coordination or structural issues in this region.

Apply this code when documentation clearly specifies dysphagia localized to the pharyngoesophageal segment. This includes conditions like cricopharyngeal dysfunction, Zenker's diverticulum causing swallowing issues, or neurological impairments affecting the pharyngeal swallow reflex. Supporting documentation should detail the phase of dysphagia.

• Differentiate from oral phase dysphagia (R13.11) or esophageal phase dysphagia (R13.13) based on physician documentation.
• Ensure the documentation explicitly states "pharyngoesophageal" or provides clinical details that localize the dysphagia to this specific phase.
• Consider co-reporting with codes for underlying conditions causing the dysphagia, such as neurological disorders or structural abnormalities.
