Fluency disorder in conditions classified elsewhere

This code signifies a disturbance in the normal flow and rhythm of speech that is a symptom or manifestation of another underlying medical condition. It describes a fluency disorder that is secondary to, or associated with, a primary diagnosis.

Use this code when documentation clearly links a patient's fluency disorder to an underlying medical condition, such as a neurological disorder, metabolic disease, or genetic syndrome, that is classified elsewhere. The medical record should specify the primary condition causing the fluency disturbance.

• Always sequence the underlying medical condition as the primary diagnosis, followed by this code.
• Ensure documentation explicitly states the fluency disorder is "due to" or "secondary to" another condition.
• Do not use this code for primary developmental or acquired fluency disorders (e.g., stuttering) unless they are explicitly linked to another classified condition.
