Stress fracture, unsp finger(s), init encntr for fracture

This diagnosis code signifies a stress fracture affecting an unspecified finger, indicating a fracture resulting from repetitive microtrauma rather than a single acute injury. It describes the initial presentation and treatment of such a fracture, where the specific digit involved is not documented.

This code is appropriate for the initial encounter when a patient presents with symptoms and imaging (e.g., X-ray, MRI) confirms a stress fracture in a finger, but the medical record does not specify which finger is affected. Documentation should clearly state "stress fracture" and "finger," and indicate that this is the first time the patient is being treated for this specific fracture.

• Ensure documentation explicitly states "stress fracture" to differentiate from acute traumatic fractures.
• If the specific finger (e.g., thumb, index finger) is identified, a more specific code from M84.34- should be used.
• The "A" seventh character indicates an initial encounter for fracture care; subsequent encounters will require different seventh characters (e.g., D for subsequent, S for sequela).
