Summary & Overview
CPT 0510T: Explantation of Sinus Tarsi Implant for Hyperpronation
CPT code 0510T denotes surgical removal of an implant located in the soft tissues between the ankle and heel bones, performed to address hyperpronation of the foot. This code captures a focused explantation procedure relevant to foot and ankle specialists and to payers managing musculoskeletal and podiatric surgical benefits. Nationally, accurate capture of this code matters for claims adjudication, episode-of-care tracking, and post-market surveillance of foot stabilizing implants.
Key payers considered in coverage and payment discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise account of the clinical context for the procedure, expected site-of-service settings, and what to expect in payer coverage conversations. The publication summarizes benchmark payment themes, coding and billing considerations tied to procedural documentation, and recent policy developments affecting outpatient implant removal procedures.
The analysis provides clinical context for the procedure, outlines the service setting, and highlights areas where documentation supports coding accuracy and medical necessity determinations. Data not available in the input is noted where specific payer policies, associated taxonomies, ICD-10 diagnoses, and related codes would normally appear.
Billing Code Overview
CPT code 0510T describes the physician removal of an implant previously attached to soft tissues located between the ankle and heel bones to treat hyperpronation of the foot. This procedure involves explantation of an implant positioned in the sinus tarsi or adjacent soft-tissue structures that were originally placed to correct excessive foot pronation.

Service type: Implant removal surgery for foot hyperpronation

Clinical & Coding Specifications
Clinical Context
A 35-year-old ambulatory patient presents to an outpatient orthopedic surgery clinic with persistent symptomatic hyperpronation (flexible flatfoot) after prior placement of a subtalar soft-tissue implant between the ankle and heel bones. The patient reports ongoing medial midfoot pain, instability, and failure of conservative care such as orthotics and physical therapy. Imaging (weight-bearing radiographs and/or CT) demonstrates appropriate implant position but ongoing clinical symptoms consistent with implant irritation or failure. The surgeon schedules removal of the previously placed soft-tissue subtalar implant under regional or general anesthesia in an ambulatory surgery center (typical site of service) or hospital outpatient department when patient comorbidities require. The clinical workflow includes preoperative evaluation, informed consent documenting reason for removal, operative removal of the implant (0510T), wound closure, postoperative recovery, and discharge with activity restrictions and follow-up. Typical providers include foot and ankle orthopedic surgeons or podiatrists with surgical privileges; anesthesia services and perioperative nursing support are involved. Documentation should include the original implant history, indication for removal (pain, infection, malposition, or failed correction), intraoperative findings, and whether additional procedures (e.g., adjacent soft-tissue repair) were performed (and reported with separate CPT codes if applicable).
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required is substantially greater than typically required for 0510T and documentation supports increased complexity. |
50 | Bilateral procedure | Use when identical implant removal is performed on both feet during the same operative session. |
51 | Multiple procedures | Use when 0510T is one of multiple distinct procedures performed during the same operative episode. |
52 | Reduced services | Use when the procedure is partially reduced or not completed as originally planned. |
53 | Discontinued procedure | Use when the procedure is started but discontinued due to extenuating circumstances. |
54 | Surgical care only | Use when the surgeon provides only the surgical portion and pre/postoperative care is billed by another provider. |
55 | Postoperative management only | Use when the surgeon bills only postoperative care for the episode related to the implant removal. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons for the same procedure. |
78 | Return to the operating room for related procedure during the postoperative period | Use when a related return to OR for revision or complication occurs after initial implant removal. |
79 | Unlisted here; not in provided list | Data not applicable — omitted per input constraints. |
80 | Assistant surgeon | Use when an assistant surgeon participates and billing for assistant-at-surgery is allowed. |
81 | Minimum assistant surgeon | Use when a minimal assistant provides limited assistance. |
82 | Assistant surgeon when qualified resident not available | Use when a qualified resident is not available and assistant services are required. |
AS | Ambulatory surgical center payment | Use to indicate the service was performed in an ambulatory surgical center on Medicare claims. |
RT | Right side | Use to indicate laterality when the implant removal is on the right side. |
