Major laceration of unsp innominate or subclav vein, sequela

This code describes the long-term effects or complications arising from a significant tear or cut in an unspecified innominate or subclavian vein. It indicates that the initial injury has resolved, but the patient continues to experience residual problems directly attributable to that major laceration.

Apply this code when documenting conditions such as chronic pain, venous insufficiency, scarring, or other persistent sequelae resulting from a previously treated major laceration of an innominate or subclavian vein. This code is appropriate for encounters where the primary focus is managing these lasting effects, not the acute injury itself.

• Always ensure documentation clearly links the current condition to the prior major laceration.
• Do not use for acute or initial treatment of the laceration; this code is exclusively for sequelae.
• Specify the laterality (left or right) if known and documented, as this code is for an unspecified side.
