In simple words: An aponeurosis is like a flat sheet extending from a tendon. This procedure involves injecting medicine into a tendon sheath, ligament, or aponeurosis to reduce pain and inflammation. The injection usually contains a corticosteroid, anesthetic, or anti-inflammatory drug. These injections are also known as trigger point injections, targeting painful knots in muscles that haven't relaxed due to injury or overuse.

The physician injects an anti-inflammatory medication using code 20550. For bilateral injections, modifier 50 would be appended, and specific joint location would be documented., A patient with de Quervain's tenosynovitis receives an injection around the affected tendon sheath in the wrist, coded as 20550.
