Hone in on Heel Spurs

Heel spur, also called calcaneal spur, may be caused by the tears in the origin of the plantar fascia at the calcaneus. The plantar fascia is a layer of fibrous connective tissue that originates in the heel bone and fans out to insert in the metatarsals. Due to excessive use or microtrauma, the plantar fascia may tear at its origin on the heel bone. If adequate healing does not occur, calcium deposits may collect to form an exostosis or protrusion, which constitutes the heel spur.

Dx code: Here are your three diagnosis coding options:

  • M77.31 — Calcaneal spur, right foot
  • M77.32 — Calcaneal spur, left foot
  • M77.30 — Calcaneal spur, unspecified foot.
