Childhood onset fluency disorder

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Stuttering or stammering that begins in childhood, characterized by involuntary repetitions, prolongations, or blocks in speech that disrupt fluency. The child knows what they want to say but has difficulty saying it smoothly.

Coding Tips

  • •Document age of onset and whether the condition is persistent or intermittent
  • •Differentiate from normal developmental disfluency in young children; this code is for persistent fluency disorders

Excludes 1 — Do NOT code together

  • adult onset fluency disorder (F98.5)
  • fluency disorder in conditions classified elsewhere (R47.82)
  • fluency disorder (stuttering) following cerebrovascular disease (I69. with final characters -23)
