AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2026 Issue 1; Section 4 – Measurement and Monitoring
Measurement of Whole-Body Mass Composition
In table 4A0, Measurement of Physiological Systems, qualifier value J Air Displacement Plethysmography, and function value E Body Composition, were added to body system value F Musculoskeletal, for approach value X External, to capture analysis of infant body composition using air displacement plethysmography.Body System Approach Function/Device Qualifier F Musculoskeletal X External E Body Composition J Air Displacement Plethysmography Technology that measures infant body mass and volume using air displacement plethysmography, such as the PEA POD® Air Displacement Plethysmography (ADP) system, measures how much air the body displaces while inside a sealed chamber. Volume changes in the chamber are...
