The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group Q86 includes congenital malformation syndromes due to known exogenous causes and not elsewhere classified, such as fetal alcohol spectrum disorders and other teratogenic exposures that lead to multisystem anomalies. These ICD-10-CM diagnosis codes are used to document patients with congenital anomalies arising from specified external causes, capturing the extent of organ involvement and developmental impact.

ICD-10-CM Q86: Congenital Malformation Syndromes Due To Known Exogenous Causes, Not Elsewhere Classified Overview
This group represents congenital malformation syndromes caused by identified external exposures that produce multiple structural anomalies present at birth, often affecting multiple organ systems. These conditions target embryologic development and commonly involve the central nervous system, craniofacial structures, limbs, and internal organs. Accurate coding is important to reflect clinical complexity and to ensure appropriate claim processing and reimbursement.
