Coding for a Knee Injection
A 68-year-old female patient with primary osteoarthritis of the left knee returns to the office for her scheduled hyaluronan injection. The patient reports that her knee is a little tender, but on a scale of 1–10, it is a 4. She is stiff in the morning for 10–20 minutes. The patient’s temperature is 98ºF, height is 5’5”, weight is 260 lbs. and BMI is 41. Her obesity is due to excess calorie intake. There was crepitus in her left knee with a large effusion. The patient receives injections of 1 mg hyaluronan into her right knee via needle guidance due to the patient’s obesity. The patient tolerates the procedure well.
