344: Other paralytic syndromes Note: This category is to be used when the listed conditions are reported without further specification or are stated to be old or long-standing but of unspecified cause. The category is also for use in multiple coding to identify these conditions resulting from any cause. Includes: paralysis (complete) (incomplete), except as classifiable to 342 and 343 Excludes: congenital or infantile cerebral palsy (343.0-343.9) hemiplegia (342.0-342.9) congenital or infantile (343.1, 343.4)
