How do you code febrile neutropenia?

Code febrile neutropenia using D70.8 for drug-induced neutropenia and R50.81 for fever. Ensure documentation includes ANC values and temperature readings.

What is the ICD-10 code for unspecified neutropenia?

The ICD-10 code for unspecified neutropenia is D70.9. Use this code when the specific cause of neutropenia is not identified.

Code Comparison: When to Use Each Code

Compare key differences between these codes to ensure accurate selection

Code	Description	When to Use	Key Documentation
D70.1	Chronic congenital neutropenia	Use for patients with confirmed congenital neutropenia, typically diagnosed in childhood.	Serial CBCs showing ANC <500 x3 episodes Genetic testing confirming congenital origin
D70.8	Other neutropenia	Use when neutropenia is secondary to drug exposure, confirmed by clinical documentation.	Documentation of drug exposure ANC drop ≥50% from baseline
D70.9	Unspecified neutropenia	Use when the specific cause of neutropenia is not determined.	Two CBCs 24h apart showing ANC <1500
P61.5	Transient neonatal neutropenia	Use for neonates with transient neutropenia, typically resolving without intervention.	Neonatal CBC showing transient ANC drop

Documentation & Coding Risks

Avoid these common issues when documenting Neutrophil Disorders.

Failure to specify drug causing neutropenia

Impact

Clinical: Inaccurate treatment planning, Regulatory: Non-compliance with coding standards, Financial: Potential for denied claims

Mitigation

Always document the specific drug and its temporal relationship to neutropenia.

Using D70.9 for all neutropenia cases

Impact

Reimbursement: May lead to lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Reduces data specificity and quality.

Mitigation

Use specific codes like D70.8 when the cause is known.

Unspecified Neutropenia

Impact

Overuse of D70.9 can trigger audits.

Mitigation

Use specific codes whenever possible and ensure documentation supports code choice.
