ICD-10 Code F48.2 – Pseudobulbar Affect (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F48.2 – Pseudobulbar affect
What it is
Pseudobulbar affect is a neurologic condition marked by sudden, involuntary episodes of laughing or crying that do not match the person’s actual mood. It reflects impaired emotional expression control, not a primary psychiatric disorder.
Clinical signs
Episodes are brief, unpredictable, and often exaggerated or difficult to stop. Clinical features vary; refer to documentation for the underlying neurologic condition and whether the emotional outbursts are clearly described as involuntary.
When to use this code
Use F48.2 when the record specifically documents pseudobulbar affect, emotional lability consistent with this diagnosis, or involuntary laughing or crying episodes. You may also use it when the clinician links the behavior to a known neurologic disorder and names pseudobulbar affect.
Do not rely on vague notes about mood changes alone. Check documentation to confirm the diagnosis is being coded as pseudobulbar affect rather than depression, anxiety, or general emotional distress.
Do not use for
Do not use this code for ordinary sadness, depression, or situational crying without involuntary episodes. Also avoid it when the chart does not clearly identify pseudobulbar affect; check documentation.
Coding tip
Code F48.2 only when the provider documents pseudobulbar affect explicitly or describes classic involuntary emotional outbursts.
