Pruritus on primarily unchanged skin L29.89

The current clinical classification bypasses this inaccurate classification and describes this condition as "pruritus on primarily unchanged skin". This designation is based on the clinical picture and is therefore easy for the clinician to classify and provides a clear guideline for a further causal research.
