Code Classification
D72.819 is a billable diagnosis code used to specify a medical diagnosis of decreased white blood cell count, unspecified. The code D72.819 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code D72.819 might also be used to specify conditions or terms like decreased blood leukocyte number, leukopenia or white blood cell number - finding.
Unspecified diagnosis codes like D72.819 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

- Leukocytopenia, unspecified
- Leukopenia
Type 1 Excludes

Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code D72.819 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 814 | RETICULOENDOTHELIAL AND IMMUNITY DISORDERS WITH MCC | 16 | 1.8907 |
| 815 | RETICULOENDOTHELIAL AND IMMUNITY DISORDERS WITH CC | 16 | 0.9925 |
| 816 | RETICULOENDOTHELIAL AND IMMUNITY DISORDERS WITHOUT CC/MCC | 16 | 0.6609 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code D72.819 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Information for Patients
Blood Disorders
Your blood is living tissue made up of liquid and solids. The liquid part, called plasma, is made of water, salts and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells and platelets.
Blood disorders affect one or more parts of the blood and prevent your blood from doing its job. They can be acute or chronic. Many blood disorders are inherited. Other causes include other diseases, side effects of medicines, and a lack of certain nutrients in your diet.
Types of blood disorders include
- Platelet disorders, excessive clotting, and bleeding problems, which affect how your blood clots
- Anemia, which happens when your blood does not carry enough oxygen to the rest of your body
- Cancers of the blood, such as leukemia and myeloma
- Eosinophilic disorders, which are problems with one type of white blood cell.
