ICD-10 Code for Proctitis
The ICD-10-CM code for proctitis is K62.89 — Other specified diseases of anus and rectum. This is the code the Alphabetic Index gives for proctitis with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
K62.89 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which proctitis code should you use?
The Alphabetic Index lists 14 codes under Proctitis. Which one applies depends on the qualifier documented in the record — the type, site, cause, or associated condition. Find the qualifier below, then verify the code in the Tabular List before using it.
