Summary & Overview
CPT 82656: Pancreatic Elastase (Fecal) Test
CPT code 82656 represents a laboratory test measuring pancreatic elastase (EL–1) in fecal specimens, commonly performed by qualitative or semi-quantitative ELISA. This test is used clinically to evaluate exocrine pancreatic function and can aid in the assessment of conditions such as cystic fibrosis, chronic pancreatic inflammation, and pancreatic neoplasms. Nationally, fecal pancreatic elastase testing is an important noninvasive diagnostic tool that supports differential diagnosis and management pathways for patients with malabsorption or suspected pancreatic insufficiency.
Key payers referenced in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides readers with operational benchmarks, clinical context for test utilization, and relevant policy considerations affecting laboratory reimbursement and coverage. It summarizes common sites of service, expected clinical indications, and how the test fits into diagnostic algorithms for pancreatic disease.
Readers will learn where CPT code 82656 is applied in practice, the typical laboratory setting for specimen processing, and the clinical scenarios in which the test is ordered. The report also outlines what is available in the input data and clearly notes where information is not provided. Data not available in the input includes detailed payer-specific reimbursement rates, associated taxonomies, ICD-10 diagnoses mapping, and related billing codes.
Billing Code Overview
CPT code 82656 describes testing for pancreatic elastase (EL–1) in a fecal specimen. The assay is typically performed using a qualitative or semi-quantitative enzyme-linked immunosorbent assay (ELISA) to assess exocrine pancreatic function.
Service Type: Laboratory test for pancreatic function assessment
Typical Site of Service: Clinical laboratory or hospital laboratory with stool specimen collection occurring in outpatient clinics or inpatient settings as clinically indicated.
Clinical & Coding Specifications
Clinical Context
A 28-year-old adult presents to gastroenterology with chronic steatorrhea, unexplained weight loss, and persistent bloating. The clinician suspects exocrine pancreatic insufficiency (EPI) possibly due to chronic pancreatitis or cystic fibrosis carrier status. A fecal pancreatic elastase test is ordered to evaluate pancreatic exocrine function. The patient collects a single stool specimen at home or in the clinic and submits it to the laboratory. The lab performs a qualitative or semi-quantitative ELISA for pancreatic elastase (EL–1) and reports results as normal, borderline, or low, which the clinician uses alongside imaging, sweat chloride testing, and clinical history to guide further evaluation or management.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | When a physician interprets the test and bills separately for the interpretation. |
TC | Technical component | When the laboratory performs the test but a separate professional interpretation is not billed. |
