K90.41 Non-celiac gluten sensitivity

ICD10CM code

#### Name of the Condition
- Non-celiac gluten sensitivity (NCGS), also known as gluten sensitivity or gluten intolerance.

#### Summary
Non-celiac gluten sensitivity is a condition characterized by gastrointestinal and extra-intestinal symptoms related to the ingestion of gluten, a protein found in wheat, barley, and rye. It occurs in individuals who do not have celiac disease or a wheat allergy.

#### Causes
The exact cause of non-celiac gluten sensitivity is unknown. It may involve an immune response to gluten or other components found in gluten-rich grains.

#### Risk Factors
- A family history of gluten-related disorders.
- Previous gastrointestinal infections.
- Increased stress levels.
- Higher sensitivity to other food components.

#### Symptoms
- Abdominal pain and bloating
- Diarrhea or constipation
- Fatigue or brain fog
- Headaches
- Joint and muscle pain

#### Diagnosis
Diagnosis is primarily based on the exclusion of other gluten-related disorders, such as celiac disease and wheat allergy. A gluten-free diet followed by a reintroduction phase may help confirm the condition if symptoms improve when gluten is removed.

#### Treatment Options
- **Gluten-free diet**: The primary treatment, which involves avoiding gluten-containing foods to alleviate symptoms.
- **Nutritional counseling**: May be beneficial to ensure a balanced diet while avoiding gluten.

#### Prognosis and Follow-Up
- Many individuals experience significant improvement in symptoms with strict adherence to a gluten-free diet.
- Regular follow-ups with a healthcare provider or dietitian are recommended to monitor symptoms and nutritional status.

#### Complications
- Persistent symptoms due to inadvertent gluten exposure.
- Potential nutritional deficiencies if the diet is not well-balanced.

#### Lifestyle & Prevention
- Adhering to a strict gluten-free diet is vital for symptom management.
- Reading food labels carefully and being aware of cross-contamination practices can help prevent symptoms.

#### When to Seek Professional Help
- If experiencing severe symptoms like unrelenting abdominal pain, significant weight loss, or malnutrition signs, seek medical advice.
- If symptoms persist despite adhering to a gluten-free diet consult a physician.

#### Tips for Medical Coders
- Ensure that the diagnosis of non-celiac gluten sensitivity does not overlap with celiac disease or wheat allergy coding.
- Code K90.41 accurately by verifying that appropriate diagnostic tests confirmed the absence of celiac disease and wheat allergy.
- Avoid confusing non-celiac gluten sensitivity with general food intolerances.
