Patient presents with complaints of anterior knee pain, consistent with patellofemoral pain syndrome (PFPS).  Symptoms include retropatellar pain, peripatellar pain, and crepitus with flexion and extension of the knee.  Onset of pain is gradual and aggravated by activities such as stair climbing, prolonged sitting, squatting, and running.  Patient denies any specific injury or trauma to the knee.  Physical examination reveals tenderness to palpation along the patellofemoral joint line and reproduction of pain with patellar compression and apprehension testing.  No effusion or instability noted.  Range of motion is within normal limits, though painful.  McMurray's test is negative.  Diagnosis of patellofemoral pain syndrome is made based on clinical presentation and physical exam findings.  Differential diagnosis includes chondromalacia patellae, patellar tendinitis, and iliotibial band syndrome.  Treatment plan includes conservative management with physical therapy focusing on strengthening of the quadriceps and hip abductors, stretching of hamstrings and iliotibial band, and patellar taping.  Patient education provided on activity modification, avoiding aggravating activities, and proper body mechanics.  Referral to orthopedic specialist will be considered if symptoms do not improve with conservative treatment within 6-8 weeks.  ICD-10 code M22.2 and CPT codes for evaluation and management (e.g., 99202-99215) and physical therapy (e.g., 97110, 97140) will be used for billing purposes.  Follow-up scheduled in 4 weeks to assess response to treatment.
