Nonspecific (abnormal) findings on radiological and other examination of musculoskeletal system

This code signifies abnormal or inconclusive findings identified during imaging studies (e.g., X-ray, MRI, CT scan) or other examinations of the musculoskeletal system, where a definitive diagnosis cannot yet be established. It indicates that an anomaly was detected, but its specific nature or cause remains undetermined.

Use this code when imaging reports or other diagnostic tests reveal an abnormality in bones, joints, muscles, or connective tissues, but the radiologist or clinician cannot provide a more specific diagnosis. This is often an interim code used while further investigation is pending to pinpoint the exact condition. Documentation should clearly state "abnormal findings," "nonspecific changes," or "further evaluation recommended."

• Do not use this code if a more specific diagnosis is available, even if it's a "probable" or "suspected" diagnosis.
• This code is typically sequenced as a secondary diagnosis when the primary reason for the encounter is the symptom prompting the imaging (e.g., pain).
• Always review the full diagnostic report; avoid coding solely from the impression if a more definitive finding is detailed elsewhere.
