ICD-10 Code R20.2
Parasthesia of skin
What is the code R20.2?
R20.2 is an ICD-10-CM code that stands for "paresthesia of skin." This code is used to identify and document the presence of abnormal skin sensations, such as tingling, prickling, or numbness, and the sensation of "pins and needles."
Detailed description of R20.2
Paresthesia of skin (R20.2) refers to a condition where an individual experiences unusual sensations on the skin. These sensations can be temporary or chronic and can occur in any part of the body. Commonly, paresthesia is associated with neurological conditions, peripheral nerve damage, or circulatory issues.
Symptoms commonly associated with R20.2
Patients with paresthesia of skin may report the following symptoms:
- Tingling or prickling sensations
- Numbness or a "pins and needles" feeling
- Burning or itching sensations
- A feeling of skin crawling
These symptoms can vary in intensity and duration, often depending on the underlying cause.
Related and similar ICD-10-CM codes
There are several ICD-10-CM codes related to R20.2 that describe similar conditions:
- R20.0: Anesthesia of skin
- R20.1: Hypoesthesia of skin
- R20.3: Hyperesthesia
- R20.8: Other disturbances of skin sensation
- G56.0: Carpal tunnel syndrome
These codes help in differentiating between various types of skin sensory disturbances.
Appropriate usage of R20.2 for billing
R20.2 should be used in billing to document cases where a patient presents with paresthesia of the skin. It is important to ensure that this code is used when paresthesia is the primary symptom being treated or evaluated. In addition to tingling, numbness, and pins and needles, there are many included signs and symptoms reported with this code.
Instructional guidelines for coding R20.2
When coding for R20.2, adhere to the following best practices:
- Ensure detailed documentation of the patient's symptoms and the areas affected.
- Rule out other potential causes or conditions that might explain the symptoms before assigning R20.2.
- Use this code in conjunction with other codes if the paresthesia is a symptom of an underlying condition.
Additional instructional notes for R20.2 include:
- Ensuring that the paresthesia is not better described by another specific condition.
- Using additional codes to identify any underlying neurological or circulatory conditions that might be contributing to the symptoms.
- Following the ICD-10-CM coding manual's guidelines for accurate and comprehensive coding.
Common pitfalls in coding with R20.2
Avoid these common mistakes when coding with R20.2:
- Using the code without sufficient documentation of the symptoms.
- Failing to differentiate between paresthesia and other types of skin sensation disturbances.
- Not considering underlying conditions that might be more accurately coded.
