K86.3 is a billable, specific ICD-10-CM code for pseudocyst of pancreas. It is valid for submission on a claim.
Excludes2 inherited from the categories above K86.3
Also inherited, and the opposite of Excludes1: these conditions are not part of K86.3, but a patient can have both, so you may code both.
Risk adjustment
K86.3 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.
