About coding anus dysplasia
The ICD-10-CM code for anus dysplasia is K62.82 (Dysplasia of anus). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on K62.82.
Within K62.8 (other specified diseases of anus and rectum), K62.82 is specifically for dysplasia of anus. Related codes cover anal sphincter tear (healed) (nontraumatic) (old) (K62.81) and other specified diseases of anus and rectum (K62.89).
Don't report K62.82 together with the conditions in its Excludes1 note: abnormal results from anal cytologic examination without histologic confirmation (R85.61-), anal intraepithelial neoplasia III (D01.3), carcinoma in situ of anus (D01.3), HGSIL of anus (R85.613) and 1 more.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
