Unspecified fracture of upper end of left ulna, sequela

This code signifies a long-term complication or late effect stemming from an unspecific fracture of the proximal (upper) end of the left ulna. The original acute injury has healed, but the patient is now experiencing residual issues directly attributable to that past fracture.

Apply this code when documentation clearly indicates a sequela (e.g., malunion, nonunion, chronic pain, deformity, restricted range of motion) resulting from a previously sustained, but unspecified, fracture of the upper end of the left ulna. This code is appropriate when the initial fracture is no longer acute and the patient is being treated for the lasting effects.

• Always ensure documentation explicitly links the current condition to a past fracture of the specified anatomical site.
• Do not use this code for acute fractures; instead, use the appropriate acute fracture code.
• Requires a seventh character "S" to indicate sequela, signifying the patient is being treated for the late effects of the injury.
