F48.2

What This Code Means

Pseudobulbar affect is a condition where a person experiences sudden, involuntary episodes of laughing or crying that are not controlled by their emotions and don't match what they're actually feeling. This neurological condition often occurs after a stroke, brain injury, or with certain neurological diseases like ALS or multiple sclerosis.

Coding Tips

• •Pseudobulbar affect is distinct from emotional lability or mood disorders—verify the diagnosis specifically states 'pseudobulbar affect' rather than general emotional instability
• •Always investigate and code the underlying cause when present (such as sequelae of stroke, ALS, MS, or other neurological conditions) as these are often the primary drivers of the condition
