Patient presents with left calf pain.  Onset, duration, character, aggravating factors, and relieving factors were explored.  Differential diagnosis includes but is not limited to muscle strain, calf muscle tear, deep vein thrombosis (DVT), peripheral artery disease (PAD), sciatica, Baker's cyst, Achilles tendinitis, and nerve entrapment.  Patient reports [onset - acute or chronic] pain described as [character - sharp, dull, aching, throbbing, cramping, burning] located in the [specific location - upper, mid, lower calf; medial, lateral, posterior].  Pain is [aggravated by - walking, standing, exercise, rest] and [relieved by - elevation, rest, ice, heat, medication].  Review of systems was conducted.  Physical exam revealed [palpation findings - tenderness, swelling, warmth, induration; range of motion; pulses - dorsalis pedis, posterior tibial; neurological exam - sensation, reflexes].  Assessment includes left lower extremity pain, rule out DVT, rule out muscle strain, rule out PAD.  Plan includes [diagnostic testing - D-dimer, venous Doppler ultrasound, arterial ultrasound, MRI, X-ray] and [treatment plan - RICE therapy (rest, ice, compression, elevation), NSAIDs, physical therapy, referral to specialist if indicated].  Patient education provided regarding activity modification, pain management, and signs and symptoms of DVT.  Follow-up scheduled as needed.  ICD-10 code [M79.604, M79.104 or other appropriate code based on suspected etiology] considered.  Medical necessity for all testing and treatment will be documented and justified based on clinical findings.
