ICD-10 Code D50.0 – Iron deficiency anemia secondary to blood loss (chronic) (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D50.0 – Iron deficiency anemia secondary to blood loss (chronic)
What it is
This code identifies iron deficiency anemia caused by ongoing blood loss over time. Use it when documentation clearly links the anemia to chronic bleeding rather than another cause.
Clinical signs
Common findings include anemia with evidence of iron depletion and a history or source of persistent blood loss. Clinical features vary; refer to documentation.
When to use this code
Use D50.0 when the provider documents iron deficiency anemia due to chronic blood loss, such as from a long-term bleeding source. You should also use it when the record states chronic blood loss as the cause and no more specific code applies.
If the anemia is attributed to another etiology, or the blood loss is acute rather than chronic, this code is not appropriate. Check documentation for the exact cause and whether the condition is confirmed.
Do not use for
Do not use this code for iron deficiency anemia without documented chronic blood loss. Avoid it when the anemia is due to acute hemorrhage or another specified cause.
Coding tip
Confirm that both iron deficiency anemia and chronic blood loss are documented together before assigning D50.0.
