Also known as
Xerostomia
Dry mouth caused by reduced or absent saliva flow.
Hypokalemia
Low potassium levels can sometimes cause dry mouth.
Sjogren's syndrome
Autoimmune disorder often causing dry eyes and mouth.
Adverse effect of medication
Certain medications can cause dry mouth as a side effect.
Follow this step-by-step guide to choose the correct ICD-10 code.

Coding dry mouth without specifying cause (e.g., medication, Sjogren's) leads to inaccurate severity and reimbursement.
Focusing solely on dry mouth symptom may lead to missing the primary diagnosis driving xerostomia, impacting treatment.
Documenting medication-induced dry mouth without confirming active medication use can cause coding errors and compliance issues.
Q: What are the most effective diagnostic tests for dry mouth (xerostomia) in a primary care setting, considering both patient comfort and diagnostic accuracy?
A: Diagnosing dry mouth often begins with a thorough patient history, including medication review and assessment of systemic conditions. While patient-reported symptoms are crucial, objective clinical evaluation is essential. Palpation of the salivary glands to assess for enlargement or tenderness can be informative. Sialometry, measuring unstimulated and stimulated salivary flow rates, provides a quantitative assessment of salivary gland hypofunction and can be easily performed in a primary care setting. Consider implementing sialometry as a routine part of your dry mouth assessment to objectively track treatment response. Explore how incorporating validated questionnaires, such as the Xerostomia Inventory, can further enhance your diagnostic approach and improve patient communication. For complex cases, referral to a specialist, such as an otolaryngologist or oral medicine specialist, may be necessary for advanced imaging or biopsies.
Q: How can I differentiate between drug-induced xerostomia and Sjogren's syndrome when evaluating a patient presenting with dry mouth symptoms?
A: Distinguishing drug-induced xerostomia from Sjogren's syndrome requires a multi-faceted approach. Start by reviewing the patient's medication list, as numerous medications, including antihistamines, antidepressants, and diuretics, can cause dry mouth as a side effect. If a causative medication is identified, consider collaborating with the prescribing physician to explore alternative medications if feasible. In contrast to drug-induced xerostomia, Sjogren's syndrome is an autoimmune disorder characterized by lymphocytic infiltration of the exocrine glands. Look for additional symptoms suggestive of Sjogren's, such as dry eyes, joint pain, and fatigue. Serological tests, like anti-SSA/Ro and anti-SSB/La antibodies, can aid in the diagnosis of Sjogren's syndrome. Lip biopsy or salivary gland scintigraphy may be necessary for definitive diagnosis in ambiguous cases. Learn more about the diagnostic criteria for Sjogren's syndrome to ensure accurate and timely diagnosis.
Patient presents with complaints of dry mouth, medically termed xerostomia, consistent with salivary gland hypofunction. Symptoms include persistent oral dryness, difficulty swallowing, altered taste sensation, and a burning sensation in the mouth. The patient also reports increased thirst and difficulty speaking for extended periods. On examination, the oral mucosa appears dry and sticky with reduced saliva pooling. The patient's medical history includes medications known to cause dry mouth as a side effect, specifically [mention medication names if applicable]. Differential diagnosis includes Sjogren's syndrome, dehydration, and medication-induced xerostomia. Diagnostic evaluation may include salivary flow rate measurement, sialography, or serologic testing for Sjogren's antibodies if clinically indicated. The current assessment suggests medication-induced dry mouth as the most likely etiology. The patient was counseled on strategies for managing dry mouth symptoms, including increasing fluid intake, using sugar-free candies and gum to stimulate saliva production, and maintaining good oral hygiene. A review of current medications will be conducted to assess for potential adjustments to minimize xerostomia side effects. Follow-up appointment scheduled in [timeframe] to monitor symptom improvement and discuss further management options if needed. ICD-10 code K11.7 for dry mouth is documented for medical billing and coding purposes. SNOMED CT code 269004002 for xerostomia is also recorded for enhanced clinical documentation specificity and interoperability within the EHR.
