Wednesday — Case #3: The Anatomy Says Something Different
Welcome to Day 3. Today we are putting one of the most important anesthesia coding habits to work: don’t code the word—code the anatomy.
THE CASE
The procedure note is titled “Saphenous Nerve Block.” The documentation describes ultrasound guidance at the mid-thigh, identification of the femoral artery beneath the sartorius muscle, advancement of the needle into the adductor canal, and deposition of local anesthetic adjacent to the saphenous nerve. The coder sees the words “saphenous nerve block” and considers selecting a code based only on the named nerve.
BEFORE YOU KEEP READING
Would you:
- A. Code strictly from the procedure title because the provider named the nerve.
- B. Review the documented anatomical approach and target before choosing the code.
- C. Choose the code with the highest reimbursement when two descriptions appear possible.
- D. Query every time the procedure title and anatomical terminology are not identical.
Make your choice: A, B, C, or D.
LET’S TALK THROUGH IT
Procedure names are helpful, but regional anesthesia coding often depends on more than the label at the top of the note. The documented target, anatomical location, approach, and technique can be critical to understanding what service was actually performed. In this case, the note gives us more information than the title alone. It describes a mid-thigh adductor canal approach with identifiable anatomical landmarks.
WHAT I WOULD LOOK FOR
- The exact anatomical location of needle placement.
- The nerve, plexus, fascial plane, or compartment targeted.
- Ultrasound-described landmarks.
- Whether the documented approach corresponds to the code under consideration.
- Whether the provider’s terminology is being used broadly or specifically.
- Whether clarification is needed because the anatomy remains ambiguous.
MY ANSWER
B — I would review and code from the documented anatomy rather than selecting a code solely because of the procedure title.
That does not mean coders should reinterpret clinical documentation or diagnose the procedure themselves. It means we should use the complete procedure note—not one isolated word—to determine whether the documentation supports the code being considered.
CODER’S CHECKPOINT
When a regional block name and the described anatomy seem different, stop before choosing the code. Trace the documented approach: where was the probe, what structure was identified, where did the needle travel, and where was the medication deposited?
TODAY’S TAKEAWAY
The title tells you what the provider called it. The anatomy helps you understand what was actually documented.
NOW IT’S YOUR TURN
Have you ever changed your initial code selection after reading the anatomical details of a block note? What clues make you stop and look closer? Put your comments below and let’s talk about it.

Thursday — Case #4: Medical Direction — One Missing Piece. Everything looks good at first glance, but one required element is not clearly supported.
