In-Office Treatment at Balance Foot & Ankle

If home treatment isn’t providing relief for your foot and ankle conditions, our podiatry team at Balance Foot & Ankle can help with expert evaluations and advanced in-office care.

Frequently Asked Questions

How long does treatment take to work?

Most patients see improvement in 4-8 weeks with consistent conservative care. Persistent symptoms after 8 weeks need imaging and escalation.

When is surgery needed?

Surgery is reserved for cases that fail 3-6 months of conservative care, structural deformities, or fractures requiring stabilization.

Is this covered by insurance?

Most diagnostic visits and conservative treatments are covered by Medicare and major insurers. Custom orthotics often require diabetic or post-surgical justification.

Balance Foot & Ankle surgeons are affiliated with Trinity Health Michigan, Corewell Health, and Henry Ford Health — three of Michigan’s largest health systems.
