Q86.8
Q86.8 — Other congenital malformation syndromes due to known exogenous causes
Billable / specific codeICD-10-CMPOA exempt
Q86.8 is a billable, specific ICD-10-CM code for other congenital malformation syndromes due to known exogenous causes. It is valid for submission on a claim.
Risk adjustment
Q86.8 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
How Q86.8 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to Q86.8.
