  • Velopharyngeal Insufficiency

    failure of the soft palate to reach the posterior pharyngeal wall to close the opening between the oral and nasal cavities. incomplete velopharyngeal closure is primarily related to surgeries (adenoidectomy; cleft palate) or an incompetent palatopharyngeal sphincter. it is characterized by hypernasal speech.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
