Clinical Significance

Unspecified disorder of the parathyroid gland represents parathyroid pathology where neither the nature nor type of dysfunction has been determined. This code indicates incomplete diagnostic workup or insufficient documentation to characterize the gland disorder.

✓Document any available lab values and imaging results.

Commonly Confused Codes
