For treatment of arthritic changes involving partial ostectomy, exostectomy, or condylectomy of the metatarsophalangeal head only, see 28288. For radiology services, see 73620-73660.
The associated diagnosis codes reported with these surgical procedures are:
M20.11: Hallux valgus (acquired)
M20.12: Hallux valgus (acquired)
M20.21: Hallux rigidus, right foot
M20.22: Hallux rigidus, left foot

If both procedures are performed on the same joint, CPT 28291 should be reported along with the appropriate T modifier since 28292 is considered a component of 28291 per current CCI edits. If documentation supports both procedure codes being billed for the DOS, they should be indicated by different T modifiers.
