Unspecified open wound of right upper arm, sequela

This code signifies an open wound on the right upper arm that is not further specified regarding its type (e.g., laceration, puncture). The "sequela" designation indicates that this code is used for a condition that is a late effect or complication of an earlier injury or disease, meaning the initial acute injury has resolved, but its lasting effects are being treated.

Use this code when documenting the long-term effects or complications of a previously sustained, unspecified open wound to the right upper arm. This would apply to situations where a patient presents for treatment of issues like chronic pain, scarring, non-healing ulcers, or other persistent problems directly attributable to an old open wound.

• Always assign an external cause code (V00-Y99) to describe the circumstances of the original injury, if known.
• Ensure documentation clearly supports the "sequela" designation, indicating the current condition is a residual effect of a past injury.
• Do not use this code for acute, current open wounds; those require codes without the "S" (sequela) seventh character.
