D61.1-D61.9Primary Range

Aplastic anemia and other bone marrow failure syndromes

This range includes codes for aplastic anemia and other bone marrow failure syndromes, which can be associated with bicytopenia.

Other specified and unspecified anemias

These codes may be used when bicytopenia is due to anemia of unspecified or other specified causes.

CodeDescriptionWhen to UseKey Documentation
D61.1Drug-induced aplastic anemia with bicytopeniaUse when bicytopenia is due to drug-induced aplastic anemia.
  • ANC <1,800
  • Hgb <12g/dL (F)/<13g/dL (M)
  • Plt <150,000
D61.818Other pancytopeniaUse when bicytopenia is idiopathic or non-drug-induced.
  • Two cytopenias with bone marrow biopsy showing hypoplasia

Clinical Decision Support

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

Key Information: ICD-10 code for bicytopenia

Essential facts and insights about Bicytopenia

Bicytopenia is coded based on its cause, such as D61.1 for drug-induced or D61.818 for other causes.

Decision Criteria

clinical Criteria

  • Documented drug-induced cause with two cytopenias.

Applicable To

  • Bicytopenia due to drug treatment

Excludes

Clinical Validation Requirements

  • ANC <1,800
  • Hgb <12g/dL (F)/<13g/dL (M)
  • Plt <150,000

Code-Specific Risks

  • Ensure drug causation is documented.

Coding Notes

  • Ensure documentation specifies drug causation and affected cell lines.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Adverse effect of antineoplastic and immunosuppressive drugs

T45.1X5A
Use with D61.1 when bicytopenia is due to chemotherapy.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Other pancytopenia

D61.818
Use D61.818 for non-drug-induced pancytopenia.

Drug-induced aplastic anemia with bicytopenia

D61.1
Use D61.1 when bicytopenia is drug-induced.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Bicytopenia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D61.1.

Impact

Clinical: Leads to mismanagement of underlying cause., Regulatory: Increases risk of non-compliance with coding standards., Financial: Potential for reduced reimbursement.

Mitigation Strategy

Always document drug name and dosage., Link cytopenia onset to drug administration.

Impact

Reimbursement: May lead to lower reimbursement rates., Compliance: Increases risk of audit due to unspecified coding., Data Quality: Reduces accuracy of clinical data.

Mitigation Strategy

Use specific codes like D61.1 or D61.818 based on etiology.

Impact

Using unspecified codes increases audit risk.

Mitigation Strategy

Document specific cell lines and causes.

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.

Documentation Templates for Bicytopenia

Use these documentation templates to ensure complete and accurate documentation for Bicytopenia. These templates include all required elements for proper coding and billing.

Bicytopenia due to chemotherapy

Specialty: Hematology

Required Elements

  • Specific cell lines affected
  • Drug name and dosage
  • Bone marrow biopsy results

Example Documentation

Patient presents with bicytopenia (Hgb 10.2 g/dL, WBC 3.2K/μL) secondary to valproic acid therapy. Bone marrow confirms reduced myeloid:erythroid ratio (1:4).

Examples: Poor vs. Good Documentation

Poor Documentation Example
Low blood counts. Will monitor.
Good Documentation Example
Bicytopenia (Hgb 10.2 g/dL, WBC 3.2K/μL) secondary to valproic acid therapy. Bone marrow confirms reduced myeloid:erythroid ratio (1:4).
Explanation
The good example specifies the cell lines, drug cause, and bone marrow findings.
