Emotional lability

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 R45.86 is a billable code used to indicate a diagnosis of emotional lability.

Key Diagnostic Point:

Emotional lability refers to rapid and exaggerated changes in mood, often characterized by sudden episodes of crying, laughing, or anger that are disproportionate to the situation. This condition can manifest in various clinical settings and may be associated with underlying psychiatric disorders, neurological conditions, or as a side effect of medications. Patients may experience emotional outbursts that seem inappropriate or excessive, leading to difficulties in social interactions and personal relationships. Emotional lability can be seen in conditions such as bipolar disorder, borderline personality disorder, traumatic brain injury, and certain neurodegenerative diseases. It is crucial for healthcare providers to assess the context of these emotional changes, including any recent stressors, medical history, and current medications, to determine the underlying cause and appropriate management strategies.
