Key Information: ICD-10 code for chemotherapy-induced neutropenia

Essential facts and insights about Chemotherapy-Induced Neutropenia

The ICD-10 code for chemotherapy-induced neutropenia is D70.1, used when neutropenia is directly attributed to chemotherapy.

Primary ICD-10-CM Code for chemotherapy induced neutropenia

Agranulocytosis secondary to cancer chemotherapy
Billable Code

Decision Criteria

clinical Criteria

  • ANC <500 cells/µL and temporal relationship to chemotherapy

documentation Criteria

  • Explicit mention of chemotherapy as the cause of neutropenia

Applicable To

  • Chemotherapy-induced neutropenia

Excludes

  • Pancytopenia due to chemotherapy (D61.818)

Clinical Validation Requirements

  • ANC <500 cells/µL during or following chemotherapy
  • Documentation of chemotherapy regimen

Code-Specific Risks

  • Incorrectly coding as unspecified neutropenia (D70.9) when chemotherapy causation is documented.

Coding Notes

  • Ensure documentation specifies 'chemotherapy-induced' to use D70.1.

Ancillary Codes

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

Fever with neutropenia

R50.81
Use when fever is present with neutropenia and is linked to chemotherapy.

Adverse effect of antineoplastic and immunosuppressive drugs

T45.1X5A
Use when neutropenia is documented as an adverse effect of chemotherapy.

Differential Codes

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

Unspecified neutropenia

D70.9
Use D70.9 only when the cause of neutropenia is not specified as chemotherapy-induced.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Chemotherapy-Induced Neutropenia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D70.1.

Impact

Clinical: Inaccurate assessment of neutropenia severity., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials due to insufficient documentation.

Mitigation Strategy

Standardize documentation templates to include ANC values., Educate staff on documentation requirements.

Impact

Reimbursement: Incorrect coding may lead to claim denials or reduced reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Impacts the accuracy of clinical data and patient records.

Mitigation Strategy

Ensure documentation explicitly states 'chemotherapy-induced neutropenia'.

Impact

Incorrect sequencing of D70.1 with ancillary codes.

Mitigation Strategy

Educate coders on proper sequencing rules.

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.

Oncology Progress Note

Specialty: Oncology

Required Elements

  • Chemotherapy regimen
  • ANC values
  • Fever details

Example Documentation

Assessment: Chemotherapy-induced neutropenia (ANC 480) secondary to cycle 3 of AC regimen for breast cancer. Febrile neutropenia (Tmax 39.1°C 24 hours post-chemo). Plan: Start cefepime IV, Filgrastim 5 mcg/kg SC daily, Monitor ANC q24h.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Neutropenia noted.
Good Documentation Example
ANC 480 (severe neutropenia) 10 days post-cycle 2 of docetaxel for breast cancer. Febrile to 38.5°C with no identifiable infection. Diagnosed as chemotherapy-induced febrile neutropenia.
Explanation
The good example provides specific ANC values, temporal relationship to chemotherapy, and links fever to neutropenia.
