Ankle Sprain That Is Not an Ankle Sprain, and a Request to Pad the Note
You are the only PT in a physician-owned outpatient clinic. A 52-year-old man is referred by a physician assistant for right ankle sprain, three weeks ago, not improving. Intake: he flew six hours from Seattle four days ago, has a history of left leg DVT five years ago, and reports the right calf tightened up over the weekend. Exam: right calf 3 cm larger than the left, diffuse tenderness, mild pitting edema, no bruising, ankle dorsiflexion limited by pain, and no clear mechanism of injury. Your boss says to keep him on the schedule for 12 visits and to document manual therapy and ultrasound each visit because that is what his insurance approves.
1. What is the single most important action in this visit, and what must you not do?
Read the worked answer
Action: stop and send him for urgent same-day evaluation for deep vein thrombosis. The picture is not an ankle sprain:
- Unilateral calf swelling of 3 cm with pitting edema and diffuse tenderness.
- A six-hour flight four days ago and a personal history of DVT.
- No mechanism of injury and no bruising, with pain limiting dorsiflexion rather than a focal ligament sign.
Contact the referring clinician and arrange same-day duplex ultrasound, or send him to urgent care/emergency if he cannot be seen promptly. Ask about and act on pulmonary embolism symptoms: new dyspnea, pleuritic chest pain, tachycardia, syncope, or hemoptysis means emergency transport, not a referral.
Do not: massage the calf, apply ultrasound, apply compression, perform vigorous stretching or joint mobilization, or schedule treatment visits before the diagnosis is settled. Mechanical compression and deep massage over a clot are contraindicated, and exercise of the limb increases venous return from a potentially unstable thrombus.
Clinically, note that calf swelling plus a negative workup still warrants a repeat scan in about a week if suspicion stays high, because a single negative study does not exclude a propagating calf clot.
2. Your boss tells you to keep the 12-visit schedule and document manual therapy and ultrasound each time. How do you respond, and what are the consequences of complying?

Refuse, in clear professional language, and offer an alternative.
'The documentation has to describe what I actually did. I have not provided manual therapy or ultrasound to this patient, and both are contraindicated while we are ruling out a clot, so writing them down would be a false claim. I will document the evaluation, the suspected DVT, the referral, and the education. I will not pre-schedule 12 visits for a diagnosis we do not have.'
Why this is not negotiable:
- Recording services that were not delivered, or that were not skilled and medically necessary, is fabrication. Billing it to a payer is fraud with civil and criminal exposure under false claims statutes.
- It exposes your license to discipline and the clinic to recoupment, fines, and payer exclusion.
- Treating a suspected DVT would also be a patient-safety violation, which is worse than the billing problem.
Constructive path: hold the schedule pending the ultrasound, tell the referral source what you found, offer to see him for evaluation and education only if that is clinically appropriate, and reschedule skilled care once cleared. If pressure continues, use the clinic compliance officer, then your state board and employer whistleblower policy. Document the request and your refusal factually.
3. The ultrasound is negative and he returns to you. Outline your plan and the red flags you teach him.

Reframe the case as a musculoskeletal problem only after the vascular question is closed. A negative scan lowers but does not eliminate suspicion, so if symptoms progress, the referral goes back.
Plan:
- Re-examine now that pain allows: clear the ankle and proximal tibia/fibula, assess calf flexibility, single-leg heel raise endurance, and gait.
- Treat with progressive loading rather than passive modalities: weight-bearing calf raises, balance, and a graded return to walking and sport.
- Address deconditioning from three weeks of guarding.
- Keep visits tied to measurable goals (heel-raise repetitions, pain-free walking distance), not to an approved visit count.
Teach him: new or worsening unilateral swelling, calf pain or warmth, chest pain, unexplained breathlessness, or fainting means seek care immediately, not at the next appointment. Also flag his prior DVT and long-haul travel as ongoing risk factors and suggest he discuss prophylaxis with his physician for future flights.
Document the reassessment, the objective change from baseline, the skilled interventions, and the education, so the record supports the medical necessity of each visit on its own merits.
