Code Classification

  • External causes of morbidity and mortality
    (V01–Y99)

      (W50-W64)
      • Accidental hit, strike, kick, twist, bite or scratch by another person

W50.3XXD is a billable diagnosis code used to specify a medical diagnosis of accidental bite by another person, subsequent encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

W50.3XXD is a subsequent encounter code, includes a 7th character and should be used after the patient has completed active treatment for a condition like accidental bite by another person. According to ICD-10-CM Guidelines a "subsequent encounter" occurs when the patient is receiving routine care for the condition during the healing or recovery phase of treatment. Subsequent diagnosis codes are appropriate during the recovery phase, no matter how many times the patient has seen the provider for this condition. If the provider needs to adjust the patient's care plan due to a setback or other complication, the encounter becomes active again.

Patient Education


Animal Bites

Wild animals usually avoid people. They might attack, however, if they feel threatened, are sick, or are protecting their young or territory. Attacks by pets are more common. Animal bites rarely are life-threatening, but if they become infected, you can develop serious medical problems.

To prevent animal bites and complications from bites:

  • Never pet, handle, or feed unknown animals
  • Leave snakes alone
  • Watch your children closely around animals
  • Vaccinate your cats, ferrets, and dogs against rabies
  • Spay or neuter your dog to make it less aggressive
  • Get a tetanus booster if you have not had one recently
  • Wear boots and long pants when you are in areas with venomous snakes

If an animal bites you, clean the wound with soap and water as soon as possible. Get medical attention if necessary.
