R20.8

Other disturbances of skin sensation

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 R20.8 is a billable code used to indicate a diagnosis of other disturbances of skin sensation.

Key Diagnostic Point:

R20.8 encompasses a variety of disturbances in skin sensation that are not classified elsewhere. This includes symptoms such as tingling, numbness, burning sensations, or altered sensitivity in the skin that cannot be attributed to a specific diagnosis. These disturbances may arise from various underlying conditions, including neuropathies, dermatological disorders, or systemic diseases. Patients may report sensations that are inconsistent with the expected physiological response to stimuli, leading to discomfort or distress. The clinical presentation can vary widely, and the disturbances may be localized or generalized. Accurate identification of the underlying cause is essential for effective management and treatment. Common causes include diabetes mellitus, multiple sclerosis, vitamin deficiencies, and peripheral nerve injuries. A thorough clinical evaluation, including a detailed history and physical examination, is crucial to determine the etiology of the symptoms and guide further diagnostic testing.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of potential underlying causes
  • Overlap with other neurological and dermatological conditions
  • Need for comprehensive patient history and examination
  • Potential for misdiagnosis if symptoms are vague

Audit Risk Factors

  • Inadequate documentation of symptoms
  • Failure to specify the underlying cause if known
  • Misuse of the code for more specific conditions
  • Lack of follow-up documentation

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Detailed patient history, including onset, duration, and characteristics of symptoms; relevant medical history; and any diagnostic tests performed.

Common Clinical Scenarios

Patients presenting with unexplained numbness or tingling in extremities, often requiring further evaluation for systemic conditions.

Billing Considerations

Consideration of comorbidities such as diabetes or thyroid disorders that may contribute to sensory disturbances.

Emergency Medicine

Documentation Requirements

Acute assessment of symptoms, including vital signs and neurological examination; documentation of any immediate interventions.

Common Clinical Scenarios

Patients presenting with acute onset of sensory disturbances, potentially indicating serious underlying conditions such as stroke or acute neuropathy.

Billing Considerations

Rapid assessment and documentation are critical to ensure appropriate coding and management.

Coding Guidelines

Inclusion Criteria

Use R20.8 When
  • Follow official ICD
  • CM guidelines for coding symptoms and signs
