Summary & Overview
CPT 27605: Percutaneous Incision of Achilles Tendon
CPT code 27605 represents a percutaneous incision of the Achilles tendon, a minor surgical procedure performed under local anesthesia to address Achilles tendinitis and to correct clubfoot deformity in pediatric patients. Nationally, this code captures a focused, low-complexity surgical intervention commonly provided in outpatient clinics and ambulatory surgery centers and is relevant to orthopedic and podiatric practice patterns.
Key payers addressed in this publication include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an explanation of the clinical context for use of 27605, typical sites of service, and common billing considerations. The report provides benchmarks where available, outlines relevant coding and billing themes for percutaneous tendon procedures, and summarizes recent policy and coverage considerations that affect reimbursement and preauthorization practices nationally.
This summary equips clinicians, billing professionals, and policy stakeholders with a concise reference to the code’s clinical intent, expected care setting, and the payer landscape for 27605. Data not available in the input will be identified in the detailed sections.

Clinical & Coding Specifications
Clinical Context
A 6-year-old child with idiopathic equinovarus (clubfoot) presents for percutaneous Achilles tendon release after serial casting (Ponseti method) failed to achieve adequate dorsiflexion. The procedure is performed in an ambulatory surgery center or clinic procedure room under local anesthesia with topical or infiltrated anesthetic. The provider prepares the distal posterior heel, applies sterile technique, palpates the tendon, and makes a small percutaneous incision to section the tendon partially or completely to lengthen it and allow corrected positioning of the foot. The patient is monitored briefly post-procedure and discharged with a long-leg cast or specialized boot; follow-up includes casting changes, wound check, and physical 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 | When a distinct E/M visit documents decision-making and medical management on the same day as the percutaneous Achilles release |
50 | Bilateral procedure | When the provider performs percutaneous Achilles tendon release on both right and left sides during the same operative session |
52 | Reduced services | When the procedure is partially reduced or not completed as originally planned |
53 | Discontinued procedure | When the procedure is started but halted due to an unforeseen complication |
59 | Distinct procedural service | When another unrelated procedure is performed at a separate anatomic site on the same day |
62 | Two surgeons | When two surgeons work together as primary surgeons on the same procedure |
78 | Unplanned return to the OR for a related procedure during the global period | When the patient returns to the operating room for a complication related to the original tendon release within the global period |
79 | Unrelated procedure or service by the same physician during the postoperative period | When an unrelated procedure is performed during the global period |
LT | Left side | To identify the left Achilles tendon procedure when laterality is required |
RT | Right side | To identify the right Achilles tendon procedure when laterality is required |
GA | Waiver of liability statement on file, voluntary under payer policy (if applicable) | When a payer requires a signed ABN-equivalent prior to elective procedure and the indicator for blanket authorization is documented |
QX | Certified registered nurse anesthetist (CRNA) service with medical direction by a physician | When anesthesia services are provided by a CRNA under the qualifying supervision model |
| Taxonomy Code | Specialty | Notes |

207V00000X | Podiatry | Podiatrists commonly perform Achilles tendon procedures, especially in adult foot and ankle pathology |
2080P0207X | Pediatric Orthopaedic Surgery | Pediatric orthopaedists commonly perform percutaneous releases for clubfoot correction |
163W00000X | Physical Medicine & Rehabilitation | May be involved in perioperative management and rehabilitation planning |
