Other specified disorders of parathyroid gland

This code represents parathyroid gland disorders that do not fit into more specific categories of hyperparathyroidism, hypoparathyroidism, or other defined parathyroid conditions. It encompasses a range of less common or atypical functional or structural abnormalities of the parathyroid glands.

Use this code when documentation indicates a parathyroid disorder that is clearly specified but lacks a more precise ICD-10-CM code. Examples include parathyroid cysts, parathyroid hemorrhage, or other non-functional anatomical anomalies not causing hyper- or hypoparathyroidism. Documentation should explicitly state the specific "other" parathyroid condition.

• Ensure documentation specifies the exact "other" parathyroid condition; avoid using this code for unspecified parathyroid disorders.
• Distinguish carefully from hyperparathyroidism (E21.0-E21.3) and hypoparathyroidism (E20.0-E20.9).
• If the "other specified" condition is a manifestation of another underlying disease, sequence the underlying disease first.
