Nondisp fx of olecran pro w intartic extn unsp ulna, sequela

This code signifies a long-term complication or late effect resulting from a previous nondisplaced fracture of the olecranon process, where the fracture line extended into the elbow joint, and the specific ulna (left or right) was not documented. It indicates that the initial injury has healed, but the patient is now experiencing residual problems or conditions directly attributable to that past fracture.

Use this code when documenting a sequela (e.g., chronic pain, stiffness, limited range of motion, nonunion, malunion, or arthritis) stemming from a previously sustained nondisplaced intraarticular olecranon fracture of an unspecified ulna. This code is appropriate for encounters where the patient is being treated for the residual effects of the old injury, not the acute fracture itself.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past olecranon fracture.
• If the laterality of the ulna is known, a more specific code (e.g., S52.034S or S52.035S) should be used instead.
