ICD-10 Code L98.8 – Other specified disorders of the skin and subcutaneous tissue (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.8 – Other specified disorders of the skin and subcutaneous tissue
What it is
L98.8 is used for skin or subcutaneous tissue disorders that are documented but do not fit a more specific ICD-10-CM code. It serves as a catch-all for named conditions that are not otherwise classified.
Clinical signs
Clinical features vary; refer to documentation. You may see localized skin changes, nodules, lesions, or tissue abnormalities that are described by the provider but not identified by a more specific diagnosis.
When to use this code
Use L98.8 when the record clearly identifies an “other specified” disorder of the skin or subcutaneous tissue and no more specific code is available. It is appropriate when the provider names a condition that is not indexed elsewhere or cannot be coded more precisely from the documentation.
Review the note for the exact diagnosis and any stated site or etiology. If the documentation supports a more specific skin disorder, code that condition instead.
Do not use for
Do not use L98.8 for common skin diseases that have their own ICD-10-CM codes, such as dermatitis, eczema, or infections. Check documentation if the condition is unspecified or better described by another code.
Coding tip
Before assigning L98.8, confirm that the provider’s wording truly indicates an “other specified” disorder and that no indexed code describes it more accurately.
