In November 2025, NHS England released a final summary of core changes between OPCS-4.10 and OPCS-4.11, a procedure coding classification updated every three years. Multiple changes were implemented, including 572 new four-character (subcategory) codes in various fields, such as cardiovascular, peripheral vascular, diagnostic imaging, endoscopy, gastroenterology, urology and nephrology, obstetrics and gynecology, men’s health, neurology and neurosurgery, pulmonology, orthopedics, spine, interventional radiology, and radiotherapy. OPCS-4.11 is expected to take effect on April 1, 2026.
