[***, MD/DO]

[Resident/PA name]

[Wide-awake local anesthesia (WALANT) with lidocaine and epinephrine / digital block / local with sedation]

The patient is a [age]-year-old [male / female] with [painful triggering / locking / snapping] of the [right / left] [thumb / index / middle / ring / small] finger consistent with stenosing tenosynovitis, Quinnell grade [II: actively correctable locking / III: passively correctable locking / IV: fixed flexion deformity]. [Conservative management including [X] corticosteroid injection(s) has failed. / Patient declined further injections.] Decision made to proceed with surgical A1 pulley release. Risks including digital nerve injury, incomplete release, stiffness, infection, and bowstringing (if A2 pulley inadvertently divided) were discussed. Informed consent was obtained.

Thickened and constricted A1 pulley over the [finger / thumb] flexor tendon sheath. Flexor tendons intact, tendon surface smooth after release. [Nodule palpable on tendon noted preoperatively / tendon surface smooth after release.] A2 pulley intact. Complete triggering resolution confirmed with active and passive flexion-extension after release.

The patient was positioned supine with the [right / left] hand on a hand table in the extended position. [Wide-awake local anesthesia with 1% lidocaine and epinephrine (1:100,000) was administered — no tourniquet required. / Digital block was administered with plain lidocaine — no epinephrine for digital block. / Local infiltration and a tourniquet was inflated at the upper arm to [250] mmHg after exsanguination.]

[For thumb:] A [transverse / longitudinal] incision of approximately 1.5 cm was made over the A1 pulley at the [MP flexion crease] of the thumb.
[For digits 2–5:] A [transverse / longitudinal] incision of approximately 1.5 cm was made over the A1 pulley at the [distal palmar crease], which overlies the proximal extent of the A1 pulley for this digit.

Dissection was carried through the skin and subcutaneous tissue. The digital neurovascular bundles were identified on each side and protected throughout — particular attention was paid to the [radial digital nerve of the thumb, which lies superficial to the A1 pulley / neurovascular bundles on either side of the flexor sheath]. The A1 pulley was identified and divided longitudinally with a [15-blade / tenotomy scissors] from its proximal to distal extent. The A2 pulley was identified and confirmed intact — the A2 pulley was not divided to avoid bowstringing. The flexor tendons were visualized: FDS and FDP intact, tendon surface smooth, no nodule. Active and passive flexion-extension confirmed complete release without triggering.

[Tourniquet released. Hemostasis achieved.] Wound irrigated. Skin closed with [4-0 Nylon / 4-0 Monocryl]. Sterile dressing applied. Patient tolerated the procedure well.

Percutaneous A1 pulley release

Technique: 18-gauge needle introduced through the skin over the A1 pulley (for digits 2–5, at the distal palmar crease; for thumb, at the MCP flexion crease), directed longitudinally along the tendon axis, and used to release the pulley with in-and-out needle passes confirmed under ultrasound or by palpation of release. Active tendon excursion confirmed after release to verify tendon integrity (the goal is A1 pulley division, not tendon division). Avoid percutaneous technique for the thumb: the radial digital nerve of the thumb lies just beneath the skin (as little as roughly 1.3 mm deep to the dermis) and follows an oblique course at the MCP joint, putting it at high risk of inadvertent injury with a blind needle technique.

Multiple digits, same session

Document each digit released individually with separate findings and release confirmation in the operative note. Medicare applies multiple-procedure reduction (50% for each procedure after the highest-valued). Multiple-procedure reporting is typically applied automatically by Medicare's claims processing system. Commercial payers vary; confirm with the individual payer.

Adult thumb trigger finger

Extra care with the radial digital nerve, which lies superficial to the A1 pulley on the radial aspect of the thumb at the MCP flexion crease — it is particularly susceptible to injury during thumb trigger release. Incision is placed at the MCP flexion crease (not the distal palmar crease used for digits 2-5). Use WALANT when possible to allow active tendon gliding confirmation intraoperatively. Document explicit identification and protection of the radial digital nerve.

Pediatric trigger thumb

Pediatric trigger thumb is developmental, not congenital (prospective newborn screening found zero cases at birth; it presents in early childhood). Spontaneous resolution is common, so observation is reasonable, especially under 1 year of age, and a delay in surgery up to age 3 is not detrimental to motion or contracture. Surgery is indicated for a rigid fixed-flexion deformity (Sugimoto stage IV) in a child older than 1 year. Children older than 1 year with persistent active (stage II) or passively correctable (stage III) triggering can either continue nonoperative measures or proceed with release, depending on family preference. Sugimoto stages: I, Notta nodule without triggering; II, active triggering; III, passively correctable triggering; IV, fixed flexion deformity. Open release under general anesthesia and tourniquet; the radial digital nerve is especially superficial in children and must be directly visualized and protected before the A1 pulley is divided. The Notta nodule itself is not addressed. Percutaneous release is not recommended in children (same radial digital nerve risk, and it does not avoid anesthesia). Document Sugimoto stage, age at surgery, and radial digital nerve identification and protection.

Charting Tips
  • State each digit released and its laterality. Claims for multiple digits require the payer's anatomical digit designation; missing or incorrect designations commonly cause denials.
  • Document digital nerve identification and protection. For digits 2–5, document bilateral neurovascular bundle protection. For the thumb, explicitly document radial digital nerve identification — the radial digital nerve of the thumb crosses superficial to the A1 pulley and is the highest-risk structure for iatrogenic injury during thumb trigger release.
  • Document A2 pulley identification and preservation. Division of the A2 pulley causes bowstringing — a recognized complication of over-aggressive distal extension of the A1 release. Document: 'the A2 pulley was identified and confirmed intact; it was not divided.'
  • Document complete release confirmation with ACTIVE (not only passive) flexion-extension. Active tendon excursion under direct visualization confirms the release is complete and the tendon is not disrupted — particularly important in wide-awake cases where patient can actively flex and extend on command. Passive-only testing can miss subtle incomplete releases.
  • Document prior conservative management for medical necessity. Record: number, date(s), and dose of corticosteroid injections; patient response and duration of relief; Quinnell grade; and duration of symptoms. The injection-to-surgery interval should be noted — deep infection risk is increased when surgery follows injection within 90 days; many hand surgeons defer surgery until 90 days after the last injection.
  • Document Quinnell grade preoperatively. Quinnell I: uneven movement; II: actively correctable locking; III: passively correctable locking; IV: fixed flexion deformity. Grade IV (fixed contracture) may be an independent surgical indication without requiring prior injection failure. The grade establishes severity and justifies surgical intervention.
Documentation & Reimbursement Considerations
  • Report Trigger Finger Release as the primary service when it is the definitive operation performed.
  • The primary service applies to any digit (thumb or finger) for open surgical release. Document which digit was treated.
  • Use the payer-required anatomic designation for each treated digit. Medicare generally applies multiple-procedure payment reductions automatically: 100% for the highest-valued procedure and 50% for each additional procedure. Document each digit released with separate findings and confirmation of release.
  • A steroid injection to a different digit's tendon sheath at the same session may be separately reportable with distinct-service reporting and appropriate digit modifier — document it as a distinct structure with a distinct indication.
  • 90-day global period: hand therapy, splinting, suture removal, and routine follow-up are bundled.
