Diseases of the blood and blood-forming organs
This chapter covers ICD-10-CM codes in the range D50-D89 for diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism. Covers disorders of blood cells, blood-forming organs, and immune mechanisms including anemias and coagulation defects.
Chapter Overview
Key Statistics
- •Contains 7 categories and 34 total codes
- •Includes 34 billable codes and 0 non-billable codes
- •Chapter range: D50-D89
Clinical Relevance
Used for hematologic conditions including anemias, coagulation disorders, and immunodeficiencies. Important for hematology, internal medicine, and laboratory correlation.
Documentation Requirements
Requires laboratory values (hemoglobin, hematocrit, coagulation studies), underlying cause identification, and severity assessment.
Special Considerations
Often requires additional codes for underlying conditions causing blood disorders. Drug-induced blood disorders need external cause codes.
Categories in this Chapter
Nutritional anemias
Hemolytic anemias
Aplastic and other anemias and other bone marrow failure syndromes
Coagulation defects, purpura and other hemorrhagic conditions
Other disorders of blood and blood-forming organs
Intraoperative and postprocedural complications of the spleen
Certain disorders involving the immune mechanism
Chapter-Specific Coding Guidelines
General Guidelines for Diseases of the blood and blood-forming organs:
- Follow standard ICD-10-CM coding principles for diseases of the blood and blood-forming organs
- Document the most specific diagnosis supported by the medical record
- Use additional codes for manifestations, complications, or associated conditions
- Ensure proper sequencing based on the reason for the encounter
Documentation Requirements:
- •Specific condition or disease process
- •Acute versus chronic status when applicable
- •Severity or stage when documented
- •Associated symptoms or complications
- •Treatment response and current status
Sequencing Rules:
- Principal diagnosis should reflect the main reason for the encounter
- Sequence complications according to treatment focus
- Use appropriate combination codes when available
- Follow chapter-specific sequencing guidelines
When to Use:
- ✓For conditions classified in the D50-D89 range
- ✓When the condition is the primary focus of care
- ✓During active treatment or monitoring
- ✓For documented complications of the condition
When NOT to Use:
- ✗For personal history without current manifestations
- ✗During screening encounters without findings
- ✗For conditions better classified elsewhere
- ✗When condition is ruled out or suspected only
Special Considerations:
- ⚠Review chapter-specific coding guidelines
- ⚠Consider combination codes before multiple codes
- ⚠Document functional impact when relevant
- ⚠Use external cause codes when applicable
