Disturbances of skin sensation

Code Description

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

Key Diagnostic Point:

Disturbances of skin sensation encompass a range of symptoms that indicate abnormal sensory perception in the skin, including numbness, tingling, burning sensations, or heightened sensitivity. These disturbances can arise from various underlying conditions, including neuropathies, dermatological disorders, or systemic diseases. Patients may report sensations that are not aligned with the actual stimuli, such as feeling pain from a light touch or experiencing a lack of sensation in certain areas. The clinical context is crucial, as these symptoms can indicate serious underlying conditions such as diabetes mellitus, multiple sclerosis, or peripheral vascular disease. A thorough history and physical examination are essential to determine the nature and extent of the sensory disturbance, and to guide further diagnostic testing, which may include nerve conduction studies, imaging, or laboratory tests to identify metabolic or autoimmune causes. Accurate documentation of the patient's symptoms, duration, and any associated factors is vital for appropriate coding and management.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying causes requiring differential diagnosis
  • Potential overlap with other neurological and dermatological codes
  • Need for detailed patient history and symptom description
  • Variability in clinical presentation among patients

Audit Risk Factors

  • Inadequate documentation of symptoms leading to vague coding
  • Failure to specify the nature of the disturbance (e.g., numbness vs. tingling)
  • Misclassification of sensory disturbances as purely dermatological
  • Lack of correlation between symptoms and documented diagnoses
