Oth fx of lower end unsp radius, init for opn fx type 3A/B/C

This code signifies an open fracture of the distal radius, specifically involving the lower end of the bone, where the type of open fracture (IIIA, IIIB, or IIIC) is not specified. It indicates the initial encounter for treatment of this injury, implying the patient is presenting for definitive care of a newly diagnosed fracture.

Use this code when documenting the initial treatment of a patient presenting with an open fracture of the distal radius where the specific Gustilo-Anderson classification (IIIA, IIIB, or IIIC) is known to be one of these types but not further specified in the medical record. This applies to emergency department visits, initial orthopedic consultations, or hospital admissions for the primary management of the fracture.

• Ensure the documentation clearly states an "open" fracture and specifies the "lower end of the radius" or "distal radius."
• Verify that the encounter is the "initial" treatment for the fracture; subsequent care would require a different encounter character.
• If the specific Gustilo-Anderson type (IIIA, IIIB, or IIIC) is documented, a more specific code within the S52.5- series should be used.
