ICD-10 Code J38.01 – Paralysis of vocal cords and larynx, unilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J38.01 – Paralysis of vocal cords and larynx, unilateral
What it is
J38.01 identifies paralysis of one vocal cord or the larynx on one side. Use it when documentation states unilateral vocal cord or laryngeal paralysis, usually affecting voice and airway function.
Clinical signs
Typical findings include hoarseness, weak voice, breathy speech, or vocal fatigue. Clinical features vary; refer to documentation, and confirm whether the paralysis is unilateral rather than bilateral or unspecified.
When to use this code
Use this code when the provider documents unilateral paralysis of a vocal cord or the larynx. It may appear after laryngeal nerve injury, surgery, tumor involvement, or other documented causes.
Code it from the record, not from suspicion alone. If the note says vocal cord paresis, immobility, or laterality is unclear, check documentation before assigning J38.01.
Do not use for
Do not use this code for bilateral vocal cord paralysis, nonspecific laryngeal disorders, or hoarseness without documented paralysis. Check documentation if the note only describes vocal cord dysfunction.
Coding tip
Always verify laterality and the exact anatomic term in the provider note before assigning J38.01.
