Code Description

ICD-10 S31.805 is a billable code used to indicate a diagnosis of open bite of unspecified buttock.

Key Diagnostic Point:

An open bite of the buttock is a type of traumatic injury characterized by a break in the skin and underlying tissues, resulting from a penetrating object or animal bite. This injury can lead to significant complications, including infection, hemorrhage, and damage to underlying structures such as muscles, nerves, and blood vessels. The buttock region is particularly vulnerable due to its anatomical complexity, which includes the gluteal muscles, sciatic nerve, and major blood vessels. In cases of open bites, immediate assessment is crucial to determine the extent of the injury and the need for surgical intervention. Emergency care may involve wound cleaning, debridement, and possibly suturing or other surgical procedures to ensure proper healing and prevent complications. The management of such injuries often requires a multidisciplinary approach, including trauma surgery, infectious disease specialists, and rehabilitation services, especially if there are associated injuries to the pelvic region or lumbar spine. Accurate coding of this condition is essential for appropriate treatment planning and reimbursement.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in documentation of injury severity
  • Potential for associated injuries in the pelvic region
  • Need for detailed descriptions of the wound and treatment
  • Differentiation from other types of buttock injuries

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to specify the location of the injury
  • Lack of follow-up documentation on treatment outcomes
  • Inconsistent coding practices across providers

Specialty Focus

Medical Specialties

Trauma Surgery

Documentation Requirements

Detailed operative notes, including the extent of the injury, surgical interventions performed, and post-operative care.

Common Clinical Scenarios

Management of open bites resulting from animal attacks or accidents, requiring surgical intervention.

Billing Considerations

Documentation must clearly outline the injury's mechanism and any associated injuries to ensure accurate coding.

Emergency Medicine

Documentation Requirements

Initial assessment notes, including vital signs, wound examination, and treatment provided in the emergency setting.

Common Clinical Scenarios

Patients presenting with open bites due to falls, assaults, or animal bites requiring immediate care.

Billing Considerations

Timely and thorough documentation is critical for coding and billing, especially in acute trauma cases.

Coding Guidelines

Inclusion Criteria

Use S31.805 When
  • According to ICD
  • CM guidelines, codes for open bites should be used to specify the site and type of injury
  • The code S31
  • 805 is used when the specific buttock is not documented
  • Coders should ensure that the documentation supports the use of this code and that any associated injuries are also coded appropriately

Exclusion Criteria

Do NOT use S31.805 When
No specific exclusions found.

Specialty Considerations

Trauma surgeons should ensure that the procedure is well-documented to support the coding.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of injuries, including open bites. This specificity helps in better tracking of injury types and outcomes, leading to improved patient care and resource allocation.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of injuries, including open bites. This specificity helps in better tracking of injury types and outcomes, leading to improved patient care and resource allocation.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of injuries, including open bites. This specificity helps in better tracking of injury types and outcomes, leading to improved patient care and resource allocation.

Frequently Asked Questions

What is the difference between an open bite and a closed bite?

An open bite involves a break in the skin and underlying tissues, while a closed bite does not penetrate the skin. Open bites are more prone to infection and require different management.
