Official coding guidelines
From the ICD-10-CM Official Guidelines for Coding and Reporting, FY 2027 (CMS and NCHS). Links open the PDF at the right page.
There are no chapter-specific rules for Chapter 3 yet, so the general rules in Section I.B apply.
All codes under D63
D63 can't be used on a claim. Pick a billable code below; grey headings group them.
D63 MS-DRGs
As the principal diagnosis, all 3 billable codes under D63 group to MS-DRG 811 or 812 (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.
About the condition
Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.
Anemia
If you have anemia, your blood does not carry enough oxygen to the rest of your body. The most common cause of anemia is not having enough iron. Your body needs iron to make hemoglobin. Hemoglobin is an iron-rich protein that gives the red color to blood. It carries oxygen from the lungs to the rest of the body.
