P94.1 is a billable ICD code used to specify a diagnosis of congenital hypertonia. A 'billable code' is detailed enough to be used to specify a medical diagnosis.


The ICD code P941 is used to code Hypertonia

Hypertonia is a term sometimes used synonymously with spasticity in the literature surrounding damage to the central nervous system, namely upper motor brain lesions. Impaired ability of damaged motor neurons to regulate descending pathways gives rise to disordered spinal reflexes, increased excitability of muscle spindles, and decreased synaptic inhibition. These consequences result in abnormally increased muscle tone of symptomatic muscles. Some authors suggest that the current definition for spasticity, the velocity-dependent over-activity of the stretch reflex, is not sufficient as it fails to take into account patients exhibiting increased muscle tone in the absence of stretch reflex over-activity. They instead suggest that “reversible hypertonia” is more appropriate and represents a treatable condition that is responsive to various therapy modalities like drug and/or physical therapy.

Other specified conditions originating in the perinatal period (approximate match)

This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code P94.1 and a single ICD9 code, 779.89 is an approximate match for comparison and conversion purposes.
