M77.31 Calcaneal spur, right foot

Name of the Condition

• Calcaneal spur, right foot

Summary

Calcaneal spur, right foot, refers to a bony outgrowth that forms on the heel bone (calcaneus) of the right foot. This condition can cause discomfort, especially when walking or standing, as the spur may press against soft tissues.

Causes

Calcaneal spur typically develops due to chronic inflammation of the plantar fascia, the thick band of tissue running along the bottom of the foot. Overuse or excessive stress on the heel, such as from repetitive activities or prolonged standing, can contribute to its formation.

Risk Factors

• Age (more common in individuals over 40)
• Obesity or excessive weight
• High-impact activities such as running or jumping
• Foot structure issues, such as flat feet or high arches
• Wearing poorly fitting or unsupportive footwear

Symptoms

• Heel pain, often worse in the morning or after prolonged sitting
• Tenderness at the base of the heel
• Swelling and inflammation in the heel area

Diagnosis

Diagnosis involves a physical examination of the foot to assess pain and tenderness. Imaging tests like X-rays may be used to visualize the spur and rule out other conditions. Assessment of gait and foot structure may also be performed.

Treatment Options

• Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation
• Physical therapy to strengthen and stretch the foot muscles
• Orthotic devices and supportive footwear to relieve pressure
• Corticosteroid injections for severe pain
• Surgery in extreme cases to remove the spur

Prognosis and Follow-Up

Prognosis is generally good with appropriate treatment, though symptoms may persist if underlying factors like foot structure or weight are not addressed. Follow-up may involve monitoring pain levels and adjusting treatment plans as needed.

Complications

• Chronic heel pain that interferes with daily activities
• Difficulty walking or standing for extended periods
• Potential development of plantar fasciitis or other foot conditions

Lifestyle & Prevention

• Maintain a healthy weight to reduce stress on the heels
• Wear supportive, well-fitting footwear
• Avoid prolonged standing or high-impact activities
• Perform regular foot stretches to improve flexibility

When to Seek Professional Help

Seek medical attention if heel pain is severe, persistent, or worsening, or if it interferes with daily activities. Prompt evaluation is recommended if swelling, redness, or warmth in the heel area is present.

Tips for Medical Coders

Use M77.31 for documentation of a calcaneal spur specifically affecting the right foot. Ensure clinical notes specify the laterality (right foot) and confirm the diagnosis through physical examination or imaging. Avoid using this code for bilateral or unspecified foot involvement.
