Overview of CPT Code 28308

CPT code 28308 describes an osteotomy procedure done on a single metatarsal bone in the foot. This involves surgically cutting and realigning the metatarsal bone to correct deformity or malalignment.

The osteotomy can be performed at either the base or shaft of the metatarsal. The metatarsal base connects to the tarsal bones. The metatarsal shaft is the long part of the bone leading to the metatarsal head.

With or without internal fixation means that metal hardware like plates, screws or pins may or may not be used to stabilize the osteotomy site.

CPT code 28308 covers the basic osteotomy procedure itself. Additional procedures like tendon transfers, arthroplasties or hammertoe correction are reported separately.

When is CPT Code 28308 Used?

Common foot conditions treated with a metatarsal osteotomy covered by 28308 include:

• Metatarsalgia – pain and inflammation in the ball of the foot
• Hallux valgus – bunion deformity of the big toe
• Metatarsus adductus – inward angling of the metatarsals and forefoot

Osteotomy realigns the metatarsal bone and helps redistribute weight-bearing forces across the ball of the foot. This can relieve pain and improve function.

Billing and Coding Guidelines

• CPT code 28308 is part of the CPT code range 28290-28315 for foot and toe repair, revision and reconstruction procedures.
• For an osteotomy of two or more metatarsal bones, report 28308 multiple times.
• If done, report internal fixation separately with CPT codes 28406 or 28407.
• Include diagnosis codes documenting the specific foot condition, laterality, and any complications.
