Clinical Context
A typical patient is an adult presenting to an outpatient endocrine surgery clinic with a thyroid nodule discovered on palpation or imaging, or a patient with hyperthyroidism being evaluated for definitive surgical management. The workflow begins with history, focused neck exam, review of prior thyroid ultrasound and fine-needle aspiration cytology, and preoperative evaluation including labs and voice assessment. The surgeon documents informed consent and operative plan. On the day of service the patient undergoes general anesthesia in an ambulatory surgery center or hospital operating room. The procedure involves identification and preservation of the recurrent laryngeal nerve and parathyroid glands, removal of part or all of the thyroid gland depending on indication, hemostasis, and wound closure. Postoperative management includes observation for bleeding, calcium monitoring for signs of hypocalcemia, voice assessment, and discharge with wound care and endocrine follow-up for thyroid hormone replacement or suppression therapy as indicated.
Coding Specifications
| Modifier | Description | When to Use |
|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure | Use when a medically necessary E/M visit is provided on the same day as the operative procedure and is properly documented as distinct from the surgery |
| 57 | Decision for surgery | Use when the E/M encounter on the day prior to or day of major surgery resulted in the decision to perform the surgery
| 59 | Distinct procedural service | Use to indicate a procedure or service that is distinct or independent from other services performed on the same day
| 76 | Repeat procedure by same physician | Use when the same procedure is repeated later the same day by the same practitioner
| 77 | Repeat procedure by another physician | Use when the same procedure is repeated later the same day by a different practitioner
| 79 | Unrelated procedure or service by the same physician during the postoperative period | Use for an unrelated procedure during the global period
| 22 | Increased procedural services | Use when the work required to provide a service is substantially greater than typically required
| 51 | Multiple procedures | Use when multiple procedures are performed at the same session by the same provider
| 50 | Bilateral procedure | Use when the procedure is performed bilaterally and the code describes a unilateral service
| 24 | Unrelated E/M service during postoperative period | Use for an E/M service unrelated to the original procedure during the global period
