ICD10 code: Linear and whorled nevoid hypermelanosis is classified under the ICD10 code Q82.8.
ICD9 code: Unfortunately, there is no specific ICD9 code for linear and whorled nevoid hypermelanosis as the ICD9 system does not provide a direct equivalent for this condition.
Linear and whorled nevoid hypermelanosis is a rare skin disorder characterized by the presence of linear or whorled patterns of hyperpigmentation on the skin. This condition typically appears in infancy or early childhood and persists throughout life. Although the exact cause of this condition is unknown, it is believed to be a result of abnormal melanocyte function.
In the International Classification of Diseases, Tenth Revision (ICD-10), the code for linear and whorled nevoid hypermelanosis is Q82.5. This code falls under the category of "Other congenital malformations of skin" and specifically refers to disorders characterized by abnormal pigmentation. It is important to note that ICD-10 codes are used for medical classification and billing purposes, allowing healthcare providers to accurately document and identify specific conditions.
In the previous version of the classification system, the ICD-9 code for this condition was 757.39. The ICD-9 code system was used prior to the implementation of ICD-10 and has since been replaced to provide a more detailed and comprehensive classification of diseases and related health problems.
Linear and whorled nevoid hypermelanosis is a unique and relatively rare condition, and the accurate coding of this disorder using the appropriate ICD-10 code ensures proper recognition and documentation in medical records.
