Pelvic floor injections
A patient with pelvic floor pain and pelvic floor muscle high-tone dysfunction was administered bilateral botulinum injections in the pelvic floor muscles. A bilateral pudendal block was given under finger guidance into the Alcock’s canal. With a finger in the vagina to confirm location and depth of the injection, botulinum was injected into two locations in each obturator internus muscle bilaterally, followed by an injection into one location in each of the pubococcygeus, ileococcygeus, coccygeus and puborectalis muscles bilaterally. The provider has documented the injections as trigger point injections. However, when injecting a toxin such as botulinum, is it more appropriate to assign a code for chemodenervation from CPT code range 64642 - 64647 ? If so, would it be appropriate to assign CPT code 64646 , Chemodenervation of trunk muscle(s); 1-5 muscle(s), to capture injections into the pelvic floor muscles? ...

Article Overview
This premium article examines coding questions arising from pelvic floor injections performed for pelvic floor pain and high-tone dysfunction. It focuses on the documentation elements that affect CPT code selection, including botulinum use, pelvic floor muscle involvement, and a related pudendal block, making it relevant to coders working in gynecology, urogynecology, pain management, and procedural coding.
Why This Topic Matters
Pelvic floor injection encounters can be difficult to code because the documented technique, treatment intent, and anatomic sites may not align cleanly with a single procedure label. Understanding the article helps coders interpret documentation for accurate CPT assignment and support consistent reporting of these specialized services.
