Your diagnosis will also need to support the appropriate injection code. Surgeons most often use ICD-9 code 726.79 (Enthesopathy of ankle and tarsus; other) to report sinus tarsi syndrome. Don't forget to use a corresponding J code to gain reimbursement for the drug that the surgeon injected.
You may consider this a joint, as the sinus tarsi traverses the sub-talar joint, so you should report 20605 (Arthrocentesis, aspiration and/or injection; intermediate joint or bursa [e.g., temporomandibular, acromioclavicular, wrist, elbow, or ankle, olecranon bursa]). Your diagnosis will also need to support the appropriate injection code.

Answer: The correct code for this procedure is hard to pin down because the sinus tarsi is neither a joint nor a ligament but a space.
The sinus tarsi is a tunnel between the talus and the calcaneus that contains structures that contribute to the stability of the ankle and to its proprioception but can get damaged in the sinus tarsi. The joint between the talus and calcaneus is also known as the subtalar joint.
It is located on the outside of the foot, just in front of your large bony bump (called the lateral malleolus) and the tunnel continues deep into the foot. The sinus tarsi provides stability to the joints of the rear foot during inversion and eversion movements.
What Is Sinus Tarsi Syndrome? Sinus tarsi syndrome is painful swelling on the outside of the joint below the ankle known as the subtalar joint. This joint allows the foot to move from side to side.
Open wound of ankle, foot and toes ICD-10-CM S91. 001A is grouped within Diagnostic Related Group(s) (MS-DRG v39.0):
The trick for coding the procedure is to be accurate with the site of injection. If your physician administers the injection into the surrounding soft tissue you need to use 20550 (Injection[s]; single tendon sheath, or ligament, aponeurosis [e.g., plantar “fascia”])...
Common symptoms of sinus tarsi syndrome include: Chronic pain along the anterolateral (front and side) part of the ankle. Pain with foot inversion (turned in) or eversion (turned out) A feeling of instability of the foot or ankle when bearing weight.
The sinus tarsi artery was formed in all cases from anastomoses between various arteries of the lateral region of the foot.
Figure 1: Anatomy of the sinus tarsi The main ligament is the ITCL. This is a wide and very strong ligament that originates from a broad attachment in the middle of the canal on the surface of the calcaneus and runs anteromedially to the deepest portion of the tarsal canal, where it inserts on the talus.

The types of open wounds classified in ICD-10-CM are laceration without foreign body, laceration with foreign body, puncture wound without foreign body, puncture wound with foreign body, open bite, and unspecified open wound. For instance, S81. 812A Laceration without foreign body, right lower leg, initial encounter.

The wound care (97597-97598) and debridement codes (11042-11047) are used for debridement of wounds that are intended to heal by secondary intention. Some conditions that support medical necessity include infections, chronic venous ulcers, and diabetic ulcers, to name a few.
