Coverage Summary

This coverage policy (Policy G2153) defines criteria and limitations for laboratory measurement of pancreatic enzymes and related biomarkers for the diagnosis and management of acute pancreatitis across commercial, BlueCare, Medicare Advantage, and DSNP members. The policy stance is mixed: serum lipase measurement is covered for individuals presenting with signs and symptoms of acute pancreatitis when criteria are met, while multiple other enzyme and biomarker measurements are not covered in most situations. The policy was last reviewed on 2025-06-04. Per a material change in the 06/04/2025 update, amylase was removed from diagnostic coverage and is no longer allowed for the diagnosis of acute pancreatitis except when used for analysis of pancreatic cyst fluid.

Provider Actions & Billing Rules

Prior Authorization

Coverage depends on individual benefit

Application of coverage criteria is dependent upon an individual's benefit coverage at the time of the request; providers must verify member benefits and any Medicare/Medicaid local or national coverage determinations that may supersede this policy.

Billing Rule

Lipase testing frequency limitation

Do not bill for measurement of serum lipase more than once per visit (claims may be denied if billed more than once per visit).

83690
Do not bill more than once per visit; claims may be denied

Background, Evidence & Definitions

Pancreatitis is inflammation of pancreatic tissue; pancreatic enzymes (including amylase, lipase, and trypsinogen) are used to assess pancreatic health because elevations can indicate pancreatic injury and depressed levels relate to exocrine pancreatic insufficiency. Biomarkers such as serum lipase are used diagnostically, while others (trypsin/trypsinogen/TAP, CRP, IL-6, IL-8, procalcitonin, urinary amylase) are discussed but noted as not meeting coverage due to limited evidence. The policy references multiple clinical guidelines and literature (including American College of Gastroenterology, AGA, IAP/APA guidelines, and systematic reviews) to support testing recommendations. A literature review completed through 06/04/2025 prompted updates to background, guidelines, and coverage — specifically removing amylase from diagnostic coverage and updating recommendations and evidence-based references.

Revision date evidence update: Literature review through 06/04/2025 prompted removal of amylase from diagnostic coverage.
