Oth injury of unsp innominate or subclavian vein, sequela

This code signifies a long-term complication or late effect resulting from a previously sustained injury to an unspecified innominate or subclavian vein, where the specific nature of the injury is known but doesn't fit into more precise categories. It indicates that the initial acute injury has resolved, but its lasting consequences are still present and require ongoing management.

Use this code when documenting conditions such as chronic venous insufficiency, post-thrombotic syndrome, persistent pain, or functional impairment directly attributable to a past, specified injury of an innominate or subclavian vein. This applies when the original injury event is no longer active, but its sequelae are being treated or evaluated.

• Always assign a code for the primary condition or manifestation of the sequela first, if applicable.
• Ensure documentation clearly links the current condition to a past injury of the specified veins.
• Do not use for acute injuries; this code is exclusively for late effects.
