Nondisplaced oblique fracture of shaft of unsp ulna, sequela

This code signifies a long-term complication or late effect stemming from a previous oblique fracture of the shaft of the ulna, where the bone fragments were not displaced at the time of the initial injury. The specific ulna (left or right) is not documented or known.

Use this code when documenting a patient presenting with ongoing issues, such as pain, limited range of motion, nonunion, malunion, or other residual problems directly attributable to a past, nondisplaced oblique ulnar shaft fracture. This code is appropriate for encounters occurring after the initial healing phase of the fracture.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., pain, nonunion).
• Ensure documentation clearly links the current condition to the previous nondisplaced oblique ulnar shaft fracture.
• Avoid using this code for the initial treatment of the acute fracture; it is exclusively for sequelae.
