ICD-10 Code D69.6 – Thrombocytopenia, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D69.6 – Thrombocytopenia, unspecified
What it is
D69.6 identifies thrombocytopenia when the record does not specify a cause. It means the patient has a low platelet count, but the documentation does not name the underlying disorder.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include easy bruising, petechiae, mucosal bleeding, or incidental laboratory evidence of low platelets.
When to use this code
Use D69.6 when the provider documents thrombocytopenia without further detail, such as “thrombocytopenia” or “low platelets” with no stated etiology. It is appropriate when the chart does not support a more specific thrombocytopenia code. If a cause is documented, code the specified condition instead.
Do not use for
Do not use this code when thrombocytopenia is clearly linked to another diagnosis, such as drug-induced, immune, or congenital thrombocytopenia. Check documentation if the record names a more specific disorder.
Coding tip
Query the provider when the cause is unclear, because a documented etiology usually supports a more specific code than D69.6.
