Emotional lability

This code describes a condition characterized by rapid, often exaggerated, and uncontrollable changes in mood or emotional expression. Patients may experience sudden shifts from laughter to tears, or from calmness to irritability, disproportionate to the precipitating event. It reflects a dysregulation of emotional responses.

Use this code when documentation explicitly states "emotional lability," "mood lability," or describes a patient exhibiting frequent, involuntary, and intense emotional fluctuations. This is often seen in neurological conditions, psychiatric disorders, or as a side effect of certain medications. Ensure the documentation clearly distinguishes this from general mood swings or affective instability.

• Do not use this code for general mood disorders where lability is a symptom; instead, code the underlying mood disorder.
• Consider sequencing this code after a primary diagnosis if emotional lability is a manifestation of another condition (e.g., traumatic brain injury, dementia).
• Ensure the provider's documentation specifies "lability" or a similar term, rather than just "unstable mood," to support this specific code.
