Summary & Overview
CPT 82710: Quantitative Fecal Fat Analysis
CPT code 82710 represents a quantitative fecal fat analysis performed on a timed stool collection (24-, 48-, or 72-hour) to detect steatorrhea and evaluate malabsorption syndromes, including workups for celiac disease. Nationally, this laboratory test supports diagnostic pathways for patients with chronic diarrhea, weight loss, or suspected fat-malabsorption and informs clinical decision-making and downstream care.
Key payers addressed in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise synthesis of clinical context, common sites of service, and typical billing considerations. The publication reviews payer coverage patterns and benchmarks where available, summarizes relevant policy considerations that affect access to testing, and explains operational implications for laboratories and ordering clinicians.
This overview is intended for a national audience of clinicians, laboratory managers, and revenue cycle staff seeking to understand the clinical purpose of CPT code 82710, typical utilization settings, and the payer landscape that drives authorization and reimbursement practices. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 82710 measures the amount of fat (lipids) excreted in a timed fecal collection. The laboratory procedure quantifies fat in a 24-, 48-, or 72-hour stool specimen to evaluate for steatorrhea and related malabsorption disorders, including suspicion for celiac disease.
-
Service type: Laboratory diagnostic test, quantitative fecal fat analysis
-
Typical site of service: Clinical laboratory or hospital laboratory; specimen is collected by the patient at home over the timed collection period and returned to the laboratory for analysis.

Clinical & Coding Specifications
Clinical Context
A 34-year-old patient presents to a gastroenterology clinic with a 3-month history of chronic loose, bulky, foul-smelling stools, unintended weight loss, and abdominal cramping. The gastroenterologist suspects fat malabsorption and celiac disease versus pancreatic insufficiency. The clinician orders a quantitative fecal fat test to measure total fat excretion over a 72-hour stool collection.
The clinical workflow: the clinician documents indication and places the order in the electronic medical record. The patient receives collection instructions and appropriate containers from the outpatient laboratory or gastroenterology clinic and collects stool over 24, 48, or 72 hours at home, storing specimens refrigerated as instructed. The completed collection is returned to the clinical laboratory or hospital outpatient lab, where the medical laboratory scientist performs extraction and gravimetric or spectrophotometric analysis to quantify total fecal fat. Results are reported to the ordering provider, who correlates fecal fat values with clinical findings, pancreatic function testing, celiac serologies, and imaging to determine diagnosis and management.
