ICD-10-PCS Code For Inferior Parathyroid Gland Left: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0GMP includes procedures performed to reattach endocrine system structures in the left inferior parathyroid gland. These ICD-10-PCS codes are used for inpatient documentation when a separated left inferior parathyroid gland is reattached to its normal or suitable location. Accurate coding within the ICD-10-PCS 0GMP group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Inferior Parathyroid Gland, Left Reattachment Procedure Overview

Procedures in this group involve reattachment of the left inferior parathyroid gland within the endocrine system to restore its anatomical continuity and function. These operations reestablish blood supply and tissue connections after separation or avulsion of the gland. Accurate ICD-10-PCS coding matters for inpatient reimbursement because it documents the specific reattachment procedure performed and supports correct case mix and payment.

When to Use

Typical Clinical Scenarios

A 45-year-old woman undergoes total thyroidectomy for a multinodular goiter and intraoperatively one left inferior parathyroid gland is inadvertently avulsed from its native bed with loss of vascular supply; the surgical team performs immediate reattachment to the original site to attempt restoration of blood flow and preserve parathyroid function during the same inpatient operation. Typical codes: 0GMP0ZZ.
An 18-year-old trauma patient arrives after a neck penetrating injury with partial separation of the left inferior parathyroid gland identified during emergency neck exploration; after stabilization and hemostasis, the surgeon reattaches the gland to a suitable location in the neck to reestablish anatomical continuity and reduce risk of hypoparathyroidism, performed during the inpatient admission. Typical codes: 0GMP0ZZ.
A 62-year-old man with prior neck surgery presents with persistent symptomatic hypocalcemia and is taken back to the operating room for exploratory reoperation; scar tissue release and microsurgical reattachment of a previously detached left inferior parathyroid gland to a vascularized bed are performed to restore gland function during the inpatient revision procedure. Typical codes: 0GMP0ZZ, 0GMP4ZZ.
