Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the R29 range.
Meningism
A condition characterized by neck stiffness, headache, and other symptoms suggestive of meningeal irritation, but without actual inflammation of the meninges (MENINGITIS). Spinal fluid pressure may be elevated but spinal fluid is normal. (DeJong, The Neurologic Examination, 4th ed, p673)
Reflex, Abnormal
An abnormal response to a stimulus applied to the sensory components of the nervous system. This may take the form of increased, decreased, or absent reflexes.
Tetany
A disorder characterized by muscle twitches, cramps, and carpopedal spasm, and when severe, laryngospasm and seizures. This condition is associated with unstable depolarization of axonal membranes, primarily in the peripheral nervous system. Tetany usually results from HYPOCALCEMIA or reduced serum levels of MAGNESIUM that may be associated with HYPERVENTILATION; HYPOPARATHYROIDISM; RICKETS; UREMIA; or other conditions. (From Adams et al., Principles of Neurology, 6th ed, p1490)
About the R29 Code Range
These symptoms and signs involve the nervous system, muscles, or skeleton. They include abnormal reflexes, abnormal posture, a clicking hip, temporary paralysis, and repeated falls.
Separate codes identify each of those findings. R29.7 groups National Institutes of Health Stroke Scale (NIHSS) scores into score bands. R29.8 identifies other symptoms and signs, while R29.9 identifies unspecified ones. Both divide further between nervous-system and musculoskeletal findings.
