| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D47.4 | Chronic myeloproliferative disease | Use for primary myelofibrosis with documented bone marrow findings and mutation status. |
|
| D75.81 | Other specified diseases of blood and blood-forming organs | Use for secondary myelofibrosis with documentation of the underlying condition. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Primary ICD-10-CM Codes for myelofibrosis
Decision Criteria
clinical Criteria
- Presence of JAK2, CALR, or MPL mutations
documentation Criteria
- Bone marrow biopsy results
Applicable To
- Chronic idiopathic myelofibrosis
- Primary myelofibrosis
Excludes
- Secondary myelofibrosis (D75.81)
Clinical Validation Requirements
- Bone marrow biopsy showing megakaryocyte proliferation and reticulin fibrosis
- JAK2, CALR, or MPL mutation status
Code-Specific Risks
- Misclassification if secondary myelofibrosis is not distinguished
Coding Notes
- Ensure documentation specifies primary versus secondary myelofibrosis.
D75.81 - Other specified diseases of blood and blood-forming organs
Use for secondary myelofibrosis with documentation of the underlying condition.
Applicable To
- Secondary myelofibrosis
Excludes
- Primary myelofibrosis (D47.4)
Clinical Validation Requirements
- Documentation of underlying condition such as post-PV or post-ET
Coding Notes
Ensure the underlying condition is documented and coded first.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Myelofibrosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D47.4.
Impact
Clinical: Inaccurate diagnosis and treatment planning., Regulatory: Non-compliance with coding standards., Financial: Potential for claim denials.
Mitigation Strategy
Ensure mutation testing is documented, Include mutation status in clinical notes
Impact
Reimbursement: Incorrect DRG assignment leading to lower reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Do not code D63.0 unless anemia requires separate treatment.
Impact
Incorrect selection of principal diagnosis can lead to audit issues.
Mitigation Strategy
Verify documentation supports the principal diagnosis choice.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
