B37.0 Candidal stomatitis

Name of the Condition

• Candidal Stomatitis (ICD Code: B37.0)
• Technical term: Candidal stomatitis
• ICD-10 Code: B37.0

Summary

Candidal stomatitis is a fungal infection of the oral mucosa caused by Candida species, most commonly Candida albicans. It is characterized by inflammation and overgrowth of yeast in the mouth, often presenting as white patches or redness. The condition typically affects the tongue, inner cheeks, gums, or roof of the mouth and may cause discomfort or pain.

Causes

Candidal stomatitis occurs when there is an overgrowth of Candida fungi, which are normally present in small amounts in the oral cavity. This overgrowth can be triggered by factors such as antibiotic use, hormonal changes, or disruptions to the oral microbiome. It may also result from reduced immune function or local irritation.

Risk Factors

• Use of antibiotics or corticosteroids.
• Weakened immune system (e.g., HIV/AIDS, chemotherapy).
• Poor oral hygiene.
• Denture use or ill-fitting dentures.
• Diabetes mellitus.
• Dry mouth (xerostomia).
• Smoking or tobacco use.

Symptoms

• White, creamy patches on the tongue, inner cheeks, or gums that may bleed when scraped.
• Redness or soreness in the mouth.
• Loss of taste or altered taste perception.
• Difficulty swallowing or pain when eating.
• Cracking or redness at the corners of the mouth (angular cheilitis).

Diagnosis

Diagnosis is typically based on clinical examination of the oral cavity, including the appearance of characteristic white patches. A healthcare provider may scrape the affected area for microscopic analysis or culture to confirm the presence of Candida. In some cases, additional tests may be performed to assess underlying risk factors.

Treatment Options

• Antifungal medications: Topical agents (e.g., nystatin, clotrimazole) applied to the mouth, or oral tablets (e.g., fluconazole) for more severe cases.
• Good oral hygiene practices, including regular brushing and denture cleaning.
• Addressing underlying causes, such as managing diabetes or discontinuing antibiotics if possible.
• Saliva substitutes or hydration to alleviate dry mouth.

Prognosis and Follow-Up

With appropriate treatment, candidal stomatitis usually resolves within 1–2 weeks. Follow-up may be recommended to ensure the infection has cleared, especially in individuals with recurrent episodes or underlying conditions. Recurrence is common in high-risk groups, requiring ongoing monitoring.

Complications

• Spread of infection to the esophagus (esophageal candidiasis), particularly in immunocompromised individuals.
• Chronic or recurrent stomatitis, leading to persistent discomfort.
• Difficulty eating or drinking due to pain or altered taste.
• Secondary bacterial infections in severe cases.

Lifestyle & Prevention

• Maintain good oral hygiene, including regular brushing and flossing.
• Clean dentures daily and remove them overnight.
• Avoid smoking or using tobacco products.
• Stay hydrated to prevent dry mouth.
• Manage underlying conditions like diabetes or immune deficiencies.
• Limit excessive sugar intake, as it can promote yeast growth.

When to Seek Professional Help

• Symptoms persist or worsen after 1–2 weeks of treatment.
• Difficulty swallowing or breathing.
• Fever or signs of systemic infection.
• Recurrent episodes despite treatment.
• Presence of white patches that do not improve with over-the-counter remedies.

Tips for Medical Coders

• Use code B37.0 for candidal stomatitis, specifying the oral location.
• Document clinical findings (e.g., white patches, redness) and any contributing factors (e.g., denture use, immunosuppression) to support coding accuracy.
• Differentiate from other oral conditions (e.g., bacterial infections, viral stomatitis) to ensure appropriate code assignment.
• Include details about treatment or follow-up if relevant to the encounter.
