Q87 ICD-10-CM Code: Other specified congenital malformation syndromes affecting multiple systems

Q87 is the ICD-10-CM diagnosis code for other specified congenital malformation syndromes affecting multiple systems. Q87 sits in the ICD-10-CM chapter for congenital malformations, deformations and chromosomal abnormalities (q00-qa0), within the section covering other congenital malformations (q80-q89).

Header codes like Q87 cannot be reported on claims directly, they organize child codes that share clinical context but the actual diagnosis must be coded to the highest level of specificity supported by the documentation. Coders should look at Q87's child codes and select the one that matches the patient's documented presentation, since payers reject header codes submitted as the primary diagnosis. For risk adjustment workflows, header codes never contribute to a Medicare Advantage member's RAF score on their own; only billable child codes that happen to map to a payment HCC affect risk-adjusted plan payments.
