Clinical InformationClinical

  • Gagging

    contraction of the muscle of the pharynx caused by stimulation of sensory receptors on the soft palate, by psychic stimuli, or systemically by drugs.

  • 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)

  • 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.

  • Gagging

    the sudden, coordinated, involuntary contraction of pharyngeal muscles in an attempt to prevent any matter from passing into the posterior pharynx; it is stimulated by touching the posterior palate, tongue, or pharynx, or by psychic stimuli.

Patient EducationClinical

Digestive Diseases

When you eat, your body breaks food down to a form it can use to build and nourish cells and provide energy. This process is called digestion.

Questions About R19.8Overview

Is R19.8 a billable code?

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

What MS-DRG does R19.8 group to?

When other specified symptoms and signs involving the digestive system and abdomen is the principal diagnosis on an inpatient stay, it groups to MS-DRG 391, 392, with relative weights from 0.7796 to 1.2683 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R19.8 be a principal diagnosis?

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

What is the ICD-9 equivalent of R19.8?

Under the General Equivalence Mappings, other specified symptoms and signs involving the digestive system and abdomen converts to ICD-9-CM 787.99 (digestve syst symptm NEC) and 789.9 (abdomen/pelvis symp 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.
