ICD-10 Code J38.00 – Paralysis of vocal cords and larynx, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J38.00 – Paralysis of vocal cords and larynx, unspecified
What it is
This code identifies paralysis of the vocal cords or larynx when the side, cause, or exact pattern is not documented. Use it for impaired laryngeal movement that affects voice or airway function.
Clinical signs
Clinical features may include hoarseness, weak voice, breathy speech, or stridor. Findings depend on the extent of paralysis; refer to documentation when laterality or severity is not specified.
When to use this code
Use J38.00 when the record clearly states vocal cord or laryngeal paralysis but does not specify unilateral, bilateral, or another detail. It also fits when the provider documents vocal cord immobility without further clarification. Check documentation if the note suggests a more specific diagnosis.
Do not use for
Do not use this code when the chart specifies unilateral or bilateral vocal cord paralysis, since a more specific code may apply. Do not assign it for hoarseness or dysphonia alone without documented paralysis.
Coding tip
If the diagnosis is vague, query for laterality or cause before defaulting to J38.00.
