Struck by volleyball, sequela

This code indicates a health condition or injury that is a lasting effect (sequela) of being struck by a volleyball. It signifies that the initial injury from the volleyball impact has resolved, but the patient is now presenting for treatment of a residual problem directly attributable to that past event.

Apply this code when a patient presents with a chronic or long-term complication stemming from a previous incident where they were hit by a volleyball. Examples include persistent pain, limited range of motion, nerve damage, or other ongoing issues directly related to the original trauma. This code is used for follow-up care of these lasting effects, not for the initial acute injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., M25.511 for right shoulder pain).
• Ensure the "S" seventh character is appended for sequela, indicating a late effect.
• Do not use this code for the initial encounter of the acute injury; instead, use the appropriate acute injury code with the "A" or "D" seventh character.
