What This Code Means
D50.0 is the ICD-10-CM diagnosis code for iron deficiency anemia secondary to blood loss (chronic). Low red blood cell count caused by ongoing or repeated blood loss, resulting in insufficient iron in the body. D50.0 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).
D50.0 is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, 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.
Identify and code the source of blood loss separately (e.g., gastrointestinal bleeding, heavy menstrual bleeding).
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for D50.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Identify and code the source of blood loss separately (e.g., gastrointestinal bleeding, heavy menstrual bleeding)
- •The 'chronic' designation indicates this is long-term; acute blood loss anemia uses a different code
