Coding Pearls

“I have a patient with a hereditary floating 2nd toe, secondary to joint instability and contracture of the extensor tendon and capsular tissue. I have decided that the most appropriate surgical procedures for the correction of this situation are a V-Y skin-plasty and an extensor tendon lengthening and are coded with CPT code 14040 and CPT code 28234, respectively. However, the ICD code M20.5×2 (Other deformities of toe(s) (acquired), left foot) does not seem to be listed as a potential diagnosis for the above CPT codes. Please help!”
