Question: Which code should we report for an iliopsoas tendon release?

Answer: You should report 27005 (Tenotomy, hip flexor[s], open [separate procedure]) if the surgeon performs the tendon release as an open procedure.
If he performs the surgery arthroscopically, you should report the unlisted-procedure code 29999 (Unlisted procedure, arthroscopy) because no arthroscopic code properly describes the iliopsoas tendon release.
