What This Code Means
D50.1 is the ICD-10-CM diagnosis code for sideropenic dysphagia. Difficulty swallowing caused by iron deficiency, often presenting as a web-like tissue in the throat that narrows the esophagus. D50.1 sits in the ICD-10-CM chapter for diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (d50-d89), within the section covering nutritional anemias (d50-d53).
D50.1 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
This is a specific manifestation of iron deficiency; code both the anemia (D50.x) and this complication.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for D50.1 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
