ICD-10 Code for Pancreatitis
Also indexed as (annular) (apoplectic) (calcareous) (edematous) (hemorrhagic) (malignant) (subacute) (suppurative)
The ICD-10-CM code for pancreatitis is K85.90 — Acute pancreatitis without necrosis or infection, unspecified. This is the code the Alphabetic Index gives for pancreatitis with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
K85.90 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which pancreatitis code should you use?
The Alphabetic Index lists 23 codes under Pancreatitis. 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.
