Lesion of lateral popliteal nerve, right lower limb

This code signifies a specific type of mononeuropathy affecting the right lateral popliteal nerve, also known as the common peroneal nerve. This condition involves damage or dysfunction of this nerve, leading to sensory and/or motor deficits in its distribution.

Use this code for documented cases of common peroneal nerve palsy or injury affecting the right lower limb. This includes conditions like foot drop, numbness over the dorsum of the foot, or weakness in ankle dorsiflexion and eversion, when attributed to a lesion of the lateral popliteal nerve. Documentation should clearly specify the right side and the nerve involved.

• Ensure documentation specifies "right lower limb" to support laterality.
• Distinguish from other lower limb mononeuropathies, such as those affecting the tibial or femoral nerves.
• Consider an additional code for the underlying cause of the lesion (e.g., trauma, compression) if known and documented.
