Nonspecific abnormal results of other specified function study

This code signifies an abnormal finding from a functional study that does not have a more specific diagnostic code. It indicates that a physiological test, beyond those specifically categorized elsewhere (e.g., cardiac, pulmonary, renal function tests), yielded an unexpected or atypical result. This code is used when the abnormality is noted but its precise nature or underlying cause is not yet determined or cannot be classified more precisely.

Use this code when documentation indicates an abnormal result from a functional study that falls outside of specific organ system function tests (e.g., neurological function studies, endocrine function studies, or other specialized physiological assessments). It is appropriate when the physician explicitly states "nonspecific abnormal results of other specified function study" or similar language, and no more definitive diagnosis or specific abnormal finding code is available.

• Avoid using this code if a more specific abnormal finding or definitive diagnosis is documented.
• Always review the full diagnostic statement and any associated findings to ensure a more precise code isn't applicable.
• This code is typically a secondary diagnosis, as it describes a finding rather than a definitive disease.
