ICD-10 Code B37.83 – Candidal cheilitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B37.83 – Candidal cheilitis
What it is
Candidal cheilitis is a yeast infection involving the lips or lip corners, caused by Candida species. You use this code when the clinician documents candidal involvement of the cheilitis.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include inflamed, cracked, or painful lips, sometimes with fissuring at the mouth corners and evidence of oral Candida involvement.
When to use this code
Use B37.83 when the provider specifically diagnoses candidal cheilitis or documents Candida infection of the lips. It may also fit when cheilitis is clearly attributed to Candida in the assessment or problem list.
Code it only when the record supports a fungal cause rather than nonspecific irritation, dryness, or allergic cheilitis. Check documentation if the note does not clearly identify Candida as the cause.
Do not use for
Do not use this code for angular cheilitis, lip inflammation from trauma, allergy, or simple chapping unless Candida is documented. Check documentation when the cause is unclear.
Coding tip
Always look for explicit wording that ties the cheilitis to Candida before assigning B37.83.
