New ICD-10-CM Code for Glanzmann Thrombasthenia Secured Through Advocacy
The National Bleeding Disorders Foundation (NBDF), in collaboration with the Glanzmann's Research Foundation and CHES Foundation, has successfully advocated for a dedicated ICD-10-CM code—D69.11—for Glanzmann thrombasthenia (GT). This rare inherited platelet disorder was previously grouped under general codes that failed to capture its unique clinical characteristics. The new code will improve diagnosis accuracy, insurance billing clarity, and data collection for research purposes. Glanzmann thrombasthenia affects blood clotting and can lead to frequent nosebleeds, easy bruising, heavy menstrual bleeding, and other serious complications. Until now, the lack of a specific ICD-10-CM code made it difficult to track prevalence, treatment patterns, and healthcare utilization for GT patients. The introduction of D69.11 will help clinicians better identify cases and support more targeted research. The new code was submitted by NBDF in 2024, reviewed in 2025, and implemented on October 1, 2026. Healthcare providers must update their systems to use the new code for patient encounters from that date onward.
