R44.8 is a billable ICD-10-CM diagnosis code for other symptoms and signs involving general sensations and perceptions. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026).

Clinical InformationClinical

  • Globus Sensation

    a feeling of a lump in the throat that occurs between meals in the absence of other gastrointestinal and motility disorders (e.g., dysphagia; gastroesophageal reflux).

  • Hyperalgesia

    an increased sensation of pain or discomfort produced by minimally noxious stimuli due to damage to soft tissue containing nociceptors or injury to a peripheral nerve.

  • Hyperesthesia

    increased sensitivity to cutaneous stimulation due to a diminished threshold or an increased response to stimuli.

  • Hypesthesia

    absent or reduced sensitivity to cutaneous stimulation.

  • Phantom Limb

    perception of painful and nonpainful phantom sensations that occur following the complete or partial loss of a limb. the majority of individuals with an amputated extremity will experience the impression that the limb is still present, and in many cases, painful. (from neurol clin 1998 nov;16(4):919-36; brain 1998 sep;121(pt 9):1603-30)

  • Sensation

    the process in which specialized sensory receptor cells transduce peripheral stimuli (physical or chemical) into nerve impulses which are then transmitted to the various sensory centers in the central nervous system.

  • Sensation Disorders

    disorders of the special senses (i.e., vision; hearing; taste; and smell) or somatosensory system (i.e., afferent components of the peripheral nervous system).

  • Somatosensory Disorders

    disorders of sensory information received from superficial and deep regions of the body. the somatosensory system conveys neural impulses which pertain to proprioception, tactile sensation, thermal sensation, pressure sensation, and pain. peripheral nervous system diseases; spinal cord diseases; and brain diseases may be associated with impaired or abnormal somatic sensation.

  • Vertigo

    an illusion of movement, either of the external world revolving around the individual or of the individual revolving in space. vertigo may be associated with disorders of the inner ear (ear, inner); vestibular nerve; brainstem; or cerebral cortex. lesions in the temporal lobe and parietal lobe may be associated with focal seizures that may feature vertigo as an ictal manifestation. (from adams et al., principles of neurology, 6th ed, pp300-1)

  • Role Playing

    the adopting or performing the role of another significant individual in order to gain insight into the behavior of that person.

  • Depersonalization

    state in which an individual perceives or experiences a sensation of unreality concerning the self or the environment; it is seen in disorders such as schizophrenia, affection disorders, organic mental disorders, and personality disorders. (apa, thesaurus of psychological index terms, 8th ed.)

  • Nociceptors

    peripheral afferent neurons which are sensitive to injuries or pain, usually caused by extreme thermal exposures, mechanical forces, or other noxious stimuli. their cell bodies reside in the dorsal root ganglia. their peripheral terminals (nerve endings) innervate target tissues and transduce noxious stimuli via axons to the central nervous system.

  • CAPS DSM-5 With DSM IV Scoring 2016 Version - Derealization|CAP01-Derealization|CAP01-Derealization|CAP0130

    clinician-administered ptsd scale (current) dsm-5 with dsm iv scoring 2016 version (caps dsm-5 with dsm iv scoring 2016 version) dsm-5 scoring: derealization: persistent or recurrent experiences of unreality of surroundings (e.g., the world around the individual is experienced as unreal, dreamlike, distant, or distorted).

  • Derealization

    a feeling of altered reality characterized by a feeling of unreality, or being unreal.

Patient EducationClinical

Psychotic Disorders

Psychotic disorders are severe mental disorders that cause abnormal thinking and perceptions. People with psychoses lose touch with reality. Two of the main symptoms are delusions and hallucinations. Delusions are false beliefs, such as thinking that someone is plotting against you or that the TV is sending you secret messages.

Questions About R44.8Overview

Is R44.8 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other symptoms and signs involving general sensations and perceptions on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Can R44.8 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the other symptoms and signs involving general sensations and perceptions is established, that condition takes the principal position instead.

What is the ICD-9 equivalent of R44.8?

Under the General Equivalence Mappings, other symptoms and signs involving general sensations and perceptions converts to ICD-9-CM 799.89 (ill-define condition NEC). The mapping is approximate, so confirm the match fits the documentation.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
