M41.00

Billable

Infantile idiopathic scoliosis, site unspecified

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

An abnormal sideways curvature of the spine that develops in infants before age 3, with no known cause, affecting an unspecified region of the spine.

Coding Tips

  • Use this code only when the specific spinal region is not documented; if region is known, use a more specific M41.02-M41.08 code
  • Infantile idiopathic scoliosis typically appears before age 3 and may resolve spontaneously or progress; document age of onset when available
