Clinical InformationClinical

  • Paraparesis

    mild to moderate loss of bilateral lower extremity motor function, which may be a manifestation of spinal cord diseases; peripheral nervous system diseases; muscular diseases; intracranial hypertension; parasagittal brain lesions; and other conditions.

  • Paraparesis, Spastic

    mild or moderate loss of motor function accompanied by spasticity in the lower extremities. this condition is a manifestation of central nervous system diseases that cause injury to the motor cortex or descending motor pathways.

  • Paraparesis, Tropical Spastic

    a subacute paralytic myeloneuropathy occurring endemically in tropical areas such as the caribbean, colombia, india, and africa, as well as in the southwestern region of japan; associated with infection by human t-cell leukemia virus i. clinical manifestations include a slowly progressive spastic weakness of the legs, increased reflexes, babinski signs, incontinence, and loss of vibratory and position sensation. on pathologic examination inflammatory, demyelination, and necrotic lesions may be found in the spinal cord. (adams et al., principles of neurology, 6th ed, p1239)

  • Akinetic Mutism

    a syndrome characterized by a silent and inert state without voluntary motor activity despite preserved sensorimotor pathways and vigilance. bilateral frontal lobe dysfunction involving the anterior cingulate gyrus and related brain injuries are associated with this condition. this may result in impaired abilities to communicate and initiate motor activities. (from adams et al., principles of neurology, 6th ed, p348; fortschr neurol psychiatr 1995 feb;63(2):59-67)

  • Mutism

    the inability to generate oral-verbal expression, despite normal comprehension of speech. this may be associated with brain diseases or mental disorders. organic mutism may be associated with damage to the frontal lobe; brain stem; thalamus; and cerebellum. selective mutism is a psychological condition that usually affects children characterized by continuous refusal to speak in social situations by a child who is able and willing to speak to selected persons. kussmal aphasia refers to mutism in psychosis. (from fortschr neurol psychiatr 1994; 62(9):337-44)

  • Pseudobulbar Palsy

    a syndrome characterized by dysarthria, dysphagia, dysphonia, impairment of voluntary movements of tongue and facial muscles, and emotional lability. this condition is caused by diseases that affect the motor fibers that travel from the cerebral cortex to the lower brain stem (i.e., corticobulbar tracts); including multiple sclerosis; motor neuron disease; and cerebrovascular disorders. (from adams et al., principles of neurology, 6th ed, p489)

  • Central Nervous System Diseases

    diseases of any component of the brain (including the cerebral hemispheres, diencephalon, brain stem, and cerebellum) or the spinal cord.

  • Frontal Lobe

    the part of the cerebral hemisphere anterior to the central sulcus, and anterior and superior to the lateral sulcus.

  • HTLV-1 Associated Myelopathy/Tropical Spastic Paraparesis|HAM/TSP|Tropical spastic paraplegia

    a progressive neurological disorder resulting in weakness or paralysis of the legs, lower back pain, and urinary symptoms. it is a sequela of infection with the htlv-1 virus.

Patient EducationClinical

Mental Disorders

Mental disorders (or mental illnesses) are conditions that affect your thinking, feeling, mood, and behavior. They may happen over a short period of time or come and go. Some can be chronic (long-lasting). They can affect your ability to relate to others and function each day..

Questions About F44.4Overview

Is F44.4 (Dissociative and conversion disorders) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report conversion disorder with motor symptom or deficit on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What is the ICD-9 equivalent of F44.4?

Under the General Equivalence Mappings, conversion disorder with motor symptom or deficit converts to ICD-9-CM 300.11 (conversion disorder). The mapping is approximate, so confirm the match fits the documentation.

Footnotes

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:

  • The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
  • The condition places limitations on self-care, independent living, and social interactions.
