From the nysora website.
In conclusion, anticoagulated patients receiving perineuraxial, deep plexus, or deep peripheral nerve blocks should be managed as if they are undergoing neuraxial anesthesia. Clinical discretion should be used for decision-making regarding the safety of other regional anesthesia techniques, such as superficial plexus blocks and nerve blocks. As an example, the vascularity and compressibility of the anatomical site where the blocks are being performed and the potential consequences of bleeding at those sites should be kept in mind. The risks of discontinuing anticoagulation therapy in these patients should be weighed versus the benefits of neuraxial and nerve block anesthesia and analgesia.
To completely dismiss the idea that INR may be relevant in a law suit or bad outcome is just ignorant of you.
