ICD-10 codes for Pancreatitis
Pancreatitis is coded primarily under K85, K85.90, K85.20 in the ICD-10-CM (Clinical Modification) classification. Top-level categories include K85 (Acute pancreatitis); K86 (Other diseases of pancreas). The 2025 ICD-10-CM code set includes 34 codes related to pancreatitis, of which 25 are billable (specific enough to appear on a medical claim).
Acute pancreatitis is coded under K85, with subcodes specifying etiology: K85.00 (idiopathic, no necrosis or infection), K85.10 (biliary), K85.20 (alcohol-induced), K85.30 (drug-induced), and additional codes for necrotizing or infected. Chronic pancreatitis uses K86 codes (alcoholic K86.0 vs other K86.1).

Yes. 25 of the 34 ICD-10-CM codes for pancreatitis are billable. Common examples include K85.00 (Idiopathic acute pancreatitis without necrosis or infection); K85.01 (Idiopathic acute pancreatitis with uninfected necrosis); K85.02 (Idiopathic acute pancreatitis with infected necrosis). Code to the highest level of specificity supported by the documentation.
Which pancreatitis ICD-10 code should I use for billing?
The most commonly used billable codes for pancreatitis include: K85.00 (Idiopathic acute pancreatitis without necrosis or infection); K85.01 (Idiopathic acute pancreatitis with uninfected necrosis); K85.02 (Idiopathic acute pancreatitis with infected necrosis).

Always code to the highest level of specificity supported by the clinical documentation.
Is K85 a billable ICD-10 code?
No, K85 (Acute pancreatitis) is a non-billable header code. You need to use a more specific child code for billing purposes.
What are the SNOMED CT concepts for pancreatitis?
The ICD-10 codes for pancreatitis map to at least 25 SNOMED CT concepts. Examples of SNOMED CT concept IDs in this group include 235943006, 235949005, 68072000, 235941008, 95563007. SNOMED CT is a clinical terminology used in electronic health records; AutoICD's coding API returns SNOMED CT IDs alongside each ICD-10 code via the include_snomed=true flag.
What UMLS Concept Unique Identifiers (CUIs) cover pancreatitis?
The ICD-10 codes for pancreatitis are linked to at least 25 UMLS CUIs in the National Library of Medicine's Metathesaurus. Sample CUIs include C0001339, C0267937, C0267938, C0341461, C4268644.
