About coding proctitis
The ICD-10-CM code for proctitis is K62.89 (Other specified diseases of anus and rectum). The official index lists 13 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K62.89.
Within K62.8, choose K62.89 (Other specified diseases of anus and rectum) only when documentation doesn't support a more specific option: anal sphincter tear (healed) (nontraumatic) (old) (K62.81) and dysplasia of anus (K62.82).
Use an additional code for any associated fecal incontinence (R15.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
