Name of the Condition

• Struck by Orca, Initial Encounter
• ICD-10 Code: W56.22XA

Summary

This condition involves an individual being struck by an orca (also known as a killer whale) for the first time. Orcas are large marine mammals known for their powerful physical capabilities.

Causes

The primary cause is physical contact with an orca, a species known for its size and strength. Such encounters may occur in marine environments, including during whale-watching tours, marine research activities, or aquatic shows.

Risk Factors

• Being in environments populated by orcas, such as open oceans or certain coastal areas.
• Engaging in water activities like scuba diving, snorkeling, or swimming in areas where orcas are present.
• Occupational exposure in marine biology, animal training, or related fields.

Symptoms

• Bruising, lacerations, or fractures resulting from the physical impact.
• Soft tissue damage or musculoskeletal injuries.
• Emotional or psychological distress following the encounter.

Diagnosis

• Medical examination to assess visible injuries.
• Imaging techniques like X-rays or MRIs to detect internal damage.
• Psychological evaluation if the encounter leads to stress or trauma.

Treatment Options

• Immediate first aid to address wounds or injuries.
• Pain management through medications.
• Surgery for severe injuries such as fractures.
• Psychological support or therapy if needed.

Prognosis and Follow-Up

• Prognosis depends on the severity of the injuries.
• Regular check-ups to monitor healing and prevent complications.
• Ongoing psychological support for emotional recovery.

Complications

• Infection from open wounds if not properly treated.
• Long-term musculoskeletal issues due to severe injuries.
• Post-traumatic stress disorder (PTSD) or anxiety concerning marine environments.

Lifestyle & Prevention

• Education on orca behavior and safe practices in marine environments.
• Use of protective equipment when in oceans known for orca populations.
• Avoiding close proximity to orcas in the wild.

When to Seek Professional Help

• Immediate medical attention for any physical injuries.
• Psychological support for distress or trauma signs.
• Follow-up care for any persistent pain or complications.

Tips for Medical Coders

• Ensure accurate initial encounter specification; use 'XA' to denote this is the first encounter.
• Double-check that "struck by" is clearly documented as the cause of injury.
• Avoid coding errors such as misclassifying the type of encounter or initial vs. subsequent encounters.
