ICD-10 Code D50.1 – Sideropenic Dysphagia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D50.1 – Sideropenic dysphagia
What it is
D50.1 identifies dysphagia associated with iron deficiency. Use it when the record shows difficulty swallowing linked to sideropenia or iron-deficiency anemia, not a general swallowing problem.
Clinical signs
Clinical features vary; refer to documentation. Typical references describe swallowing difficulty, often with other signs of iron deficiency such as pallor or fatigue, but the chart should support the association.
When to use this code
Use D50.1 when the clinician documents sideropenic dysphagia, Plummer-Vinson syndrome, or swallowing difficulty clearly tied to iron deficiency. It fits cases where the diagnosis is specific, not merely suspected. If the note only says dysphagia, code the swallowing symptom or the documented underlying condition instead.
Do not use for
Do not use this code for dysphagia from neurologic, structural, reflux, or malignant causes. Check documentation if iron deficiency is not stated or the link between anemia and swallowing difficulty is unclear.
Coding tip
Assign D50.1 only when the provider connects dysphagia to iron deficiency in the record.
