About coding palmaris et plantaris keratosis
The ICD-10-CM code for palmaris et plantaris keratosis is Q82.8 (Other specified congenital malformations of skin). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Q82.8.
Within Q82, choose Q82.8 (Other specified congenital malformations of skin) only when documentation doesn't support a more specific option: hereditary lymphedema (Q82.0), Xeroderma pigmentosum (Q82.1), congenital cutaneous mastocytosis (Q82.2), Incontinentia pigmenti (Q82.3), ectodermal dysplasia (anhidrotic) (Q82.4), congenital non-neoplastic nevus (Q82.5), congenital sacral dimple (Q82.6) and congenital malformation of skin, unspecified (Q82.9).
Don't report Q82.8 together with the conditions in its Excludes1 note: Ehlers-Danlos syndromes (Q79.6-).
The conditions in its Excludes2 note aren't part of Q82.8, but may be coded alongside it if the patient has both: disorders of pyrophosphate metabolism (E83.82-).
