Break Down Descriptions to Uncover Transposition Code
Published on Sun Dec 01, 2002
Test your coding knowledge. Determine how you would code this situation before looking at the box below for the answer.
Question: A patient presented with severe nerve palsy. My ophthalmologist's operative notes report cutting of the superior oblique tendon at the medial border of the superior rectus muscle and 2 mm anterior to the medial insertion of the superior rectus muscle. He also reported recessing the lateral rectus muscle. How should I code all of this?

Answer: To ensure accurate coding, break down each service description into "codeable" language.
Determine which muscles were operated on and what was done to them.
The first piece of information to note is the "cutting of the superior oblique tendon." This wording may throw you off if you don't know that the superior oblique muscle is also known as the superior oblique tendon. This is the muscle that wraps around the eyeball, and its recession or resection is described by 67318 (Strabismus surgery, any procedure, superior oblique muscle).
The second important piece of information is the recession of the lateral rectus muscle, a horizontal muscle, which can be coded 67311 (Strabismus surgery, recession or resection procedure; one horizontal muscle). You must append modifier -51 (Multiple procedures) to 67311 to indicate that more than one procedure was performed on the same site.
