About coding cecum polyp
The ICD-10-CM code for cecum polyp is K63.5 (Polyp of colon). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on K63.5.
Within K63 (other diseases of intestine), K63.5 is specifically for polyp of colon. Related codes cover abscess of intestine (K63.0), perforation of intestine (nontraumatic) (K63.1), fistula of intestine (K63.2), ulcer of intestine (K63.3), Enteroptosis (K63.4), other specified diseases of intestine (K63.8) and disease of intestine, unspecified (K63.9).
The conditions in its Excludes2 note aren't part of K63.5, but may be coded alongside it if the patient has both: adenomatous polyp of colon (D12.-), inflammatory polyp of colon (K51.4-) and polyposis of colon (D12.6).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
