Code Description

ICD-10 R06.6 is a billable code used to indicate a diagnosis of hiccough.

Key Diagnostic Point:

Hiccough, commonly known as hiccups, is an involuntary contraction of the diaphragm muscle followed by a sudden closure of the vocal cords, producing a characteristic 'hic' sound. This reflex action can occur sporadically or persistently and may be triggered by various factors including overeating, consuming carbonated beverages, sudden temperature changes, or emotional stress. While hiccups are usually benign and self-limiting, persistent hiccups lasting more than 48 hours may indicate underlying medical conditions such as gastroesophageal reflux disease (GERD), central nervous system disorders, or metabolic imbalances. Clinicians should assess the duration, frequency, and associated symptoms to determine the underlying cause and appropriate management. Diagnostic approaches may include a thorough history and physical examination, and in some cases, imaging studies or laboratory tests may be warranted to rule out serious conditions. Accurate documentation of the patient's symptoms, duration, and any precipitating factors is essential for proper coding and management.
