Hiccough

This code represents the involuntary, spasmodic contraction of the diaphragm and intercostal muscles, followed by sudden closure of the glottis, producing the characteristic "hic" sound. It describes an episode of hiccups that is typically benign and self-limiting, without an identified psychological origin.

Use this code for transient or persistent episodes of hiccups documented in the patient's record where no underlying psychogenic cause is indicated. Documentation should clearly state "hiccups" or "hiccough" as the primary complaint or an associated symptom.

• Do not use this code if documentation specifies a psychogenic origin; refer to F45.8 instead.
• Consider if the hiccups are a symptom of another underlying condition; if so, code the underlying condition first, followed by this code if clinically significant.
• Ensure the medical record clearly distinguishes between acute, persistent, or intractable hiccups if further specificity is available, though this code covers all general presentations.
