Summary & Overview
CPT 28222: Flexor Tendon Adhesion Release, Foot
CPT code 28222 represents a surgical release of adhesions involving multiple flexor tendons in the foot. The procedure addresses restricted tendon motion and pain from tendonitis or postoperative scar formation and is an important intervention for restoring function in affected patients. Nationally, this code is relevant across hospital and ambulatory surgical settings where foot and ankle surgical care is delivered.
Key payers commonly involved in coverage decisions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Payer policies can affect prior authorization requirements, medical necessity criteria, and coverage of related perioperative services.

Clinical & Coding Specifications
Clinical Context
A 52-year-old recreational runner presents with persistent medial forefoot pain, stiffness, and reduced toe flexion despite 6 months of conservative care including physical therapy, activity modification, orthotics, and corticosteroid injection. Examination shows tender, palpable cord-like bands along the plantar aspect with limited active flexion of multiple toes. Imaging (ultrasound/MRI) demonstrates adhesions and scarring involving multiple flexor tendons of the foot consistent with tenosynovitis and adhesions. The surgeon schedules a planned outpatient operative release of adhesions under regional or general anesthesia to restore tendon glide and relieve pain. Typical workflow includes preoperative evaluation, informed consent documenting procedure 28222, anesthesia clearance, intraoperative exploration and tenolysis of involved flexor tendons, wound closure with sterile dressing, postoperative recovery with weight-bearing instructions, and referral for postoperative rehabilitation to regain range of motion and strength. Typical site of service is an ambulatory surgical center or hospital outpatient department. The procedure is performed by an orthopedic foot and ankle surgeon or podiatric surgeon trained in tendon surgery.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | Use when billing only the surgeon's professional service separate from facility charges (rare for this operative code). |
50 | Bilateral procedure | Use when identical tenolysis is performed on both feet during the same operative session. |
51 | Multiple procedures | Use when 28222 is reported with other distinct procedures during the same operative episode. |
52 | Reduced services | Use when the procedure is partially performed or incomplete due to intraoperative findings. |
53 | Discontinued procedure | Use if the procedure is started but terminated for extenuating circumstances prior to completion. |
59 | Distinct procedural service | Use to indicate separate and unrelated procedures performed at different anatomic sites or greater than usual separate procedural service. |
62 | Two surgeons | Use when two surgeons with different specialties operate together and both report their services. |
78 | Return to OR for related procedure during global period | Use when the patient returns to the operating room for a related procedure during the postoperative global period. |
79 | unrelated procedure during global period | Data not available in the input. |
