Unspecified open wound of unspecified upper arm, sequela

This code signifies a long-term complication or late effect resulting from an open wound on an unspecified part of the upper arm. The original wound's specific nature (e.g., laceration, puncture) is not documented, nor is the precise location on the upper arm.

Utilize this code when documenting a current condition that is a direct consequence of a previously healed or resolved open wound of the upper arm, and the original wound's details are unknown or not specified. This applies to scenarios such as chronic pain, scarring, or functional limitations directly attributable to the past injury.

• Always assign a seventh character of "S" for sequela when using this code.
• Ensure documentation clearly links the current condition to a past open wound of the upper arm.
• Avoid this code if the specific type of open wound or the exact location on the upper arm is known; instead, use a more specific sequela code.
