Exposure to other inanimate mechanical forces, sequela

This code signifies a long-term or late-effect condition resulting from an injury caused by an unspecified inanimate mechanical force. It indicates that the initial acute injury has resolved, but residual symptoms, complications, or conditions persist. This category is used when the specific nature of the inanimate mechanical force is not documented.

Use this code when documenting a sequela of an injury where the original cause was an inanimate mechanical force, but the specific type (e.g., crushing, striking, pushing) is unknown or unstated. This applies to conditions such as chronic pain, scar tissue, limited range of motion, or nerve damage that are directly attributable to a past injury from an unspecified mechanical force.

• Always sequence this code after the code for the specific sequela (e.g., chronic pain, scar, deformity).
• Avoid using this code for acute injuries; it is exclusively for late effects or complications.
• If the specific inanimate mechanical force is known, a more specific W49 subcategory should be used.
