    What about 733.90? However, this is an unspecified code. I'd talk to your provider to see if he/she can help you come up with something more specific.

    Fibrous Cortical Defect it's a common small defect of a bone, in which the cortex is filled with fibrous tissue. Also called as Non -Ossifying Fibroma.

    So I think, 733.29 is appropriate code.

    Go thro' Fibroma --> nonosteogenic(i.e. Nonossifying), which stated see also

    Dysplasia - -> Fibrous - -> Bone - -> 733.29.

    Hope this helps.
