Nondisp segmental fx shaft of ulna, left arm, sequela

This code signifies a healed or chronic complication resulting from a fracture in the middle section of the left ulna bone, where the bone fragments remained in their normal anatomical alignment during the initial injury. The "sequela" indicates that the patient is presenting for treatment of a residual condition directly attributable to this past fracture, such as malunion, nonunion, pain, or functional limitation.

Use this code when documenting a patient encounter for a long-term complication or residual effect of a previously sustained, nondisplaced segmental fracture of the shaft of the left ulna. This applies to situations where the initial fracture has healed, but the patient continues to experience issues related to that injury. Examples include chronic pain, stiffness, or deformity at the fracture site.

• Always use an additional code to specify the nature of the sequela (e.g., M84.422A for malunion, M96.0 for pseudarthrosis).
• Ensure documentation clearly states the fracture is "nondisplaced" and "segmental" and located on the "left ulna shaft."
• This code is for sequela only; do not use for initial or subsequent encounters for active fracture treatment.
