Monoplegia of lower limb affecting unspecified side

This code signifies paralysis affecting a single lower extremity, without specifying whether it's the left or right leg. It indicates a loss of motor function in one leg due to neurological impairment.

Apply this code when documentation clearly states monoplegia of a lower limb but does not specify the affected side. This is appropriate when the laterality is unknown or not documented by the provider.

• Avoid using this code if the laterality (left or right) is specified in the medical record; instead, use the more specific G83.11 or G83.12.
• Ensure the documentation explicitly states "monoplegia" or "paralysis of one leg" to support this code.
• Always query the provider for laterality if it's missing, as more specific codes are preferred for accurate reporting.
