ICD-10 Code D61.811 – Other drug-induced pancytopenia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D61.811 – Other drug-induced pancytopenia
What it is
This code identifies pancytopenia caused by a medication or drug exposure, when the record specifies an other drug-induced cause. It means all three blood cell lines are reduced and the cause is attributed to a drug.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include anemia, infection risk from low white cells, and bleeding or bruising from low platelets, but the chart should link the condition to a drug cause.
When to use this code
Use D61.811 when the provider documents pancytopenia due to a medication, and the drug cause is not better captured by another specific code. You should code from the documented diagnosis, not from suspicion alone. If the note states an adverse effect from a drug with pancytopenia, this code may apply.
Do not use for
Do not use this code for pancytopenia from chemotherapy when a more specific code is documented. Do not use it when the cause is unknown or when the record only mentions anemia or thrombocytopenia alone.
Coding tip
Verify the provider’s causal wording and code the implicated drug separately when required.
