R10.819

Abdominal tenderness, unspecified site

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R10.819 is a billable code used to indicate a diagnosis of abdominal tenderness, unspecified site.

Key Diagnostic Point:

Abdominal tenderness is a clinical sign characterized by discomfort or pain upon palpation of the abdomen. It is a nonspecific finding that can indicate a variety of underlying conditions, ranging from benign to serious. The tenderness may be localized or generalized and can be associated with other symptoms such as nausea, vomiting, diarrhea, or fever. Common causes of abdominal tenderness include gastrointestinal disorders (e.g., appendicitis, pancreatitis, diverticulitis), infections, and inflammatory conditions. The assessment of abdominal tenderness is crucial in the clinical evaluation of patients presenting with abdominal complaints, as it can guide further diagnostic testing and management. However, because this code is for unspecified site tenderness, it is essential for clinicians to document the location and characteristics of the tenderness to provide a clearer clinical picture and assist in accurate coding.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in documentation of tenderness location
  • Need for correlation with other clinical findings
  • Potential overlap with other abdominal pain codes
  • Differentiation from more specific abdominal tenderness codes

Audit Risk Factors

  • Inadequate documentation of the site of tenderness
  • Failure to link tenderness to a specific diagnosis
  • Use of this code when a more specific code is available
  • Lack of supporting clinical findings in the medical record

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Detailed documentation of the patient's history, physical examination findings, and any diagnostic tests performed is essential. The location, severity, and duration of tenderness should be clearly noted.

Common Clinical Scenarios

Patients presenting with vague abdominal pain, requiring further evaluation to rule out serious conditions.

Billing Considerations

Consideration of comorbidities and the patient's overall clinical picture is crucial for accurate coding.

Emergency Medicine

Documentation Requirements

Acute care documentation must include a thorough assessment of the abdomen, including the presence of tenderness, associated symptoms, and any immediate interventions.

Common Clinical Scenarios

Patients with acute abdominal pain requiring rapid assessment and possible surgical intervention.

Billing Considerations

Emergency settings may necessitate expedited documentation, but clarity on tenderness location is still vital.

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding options, but it has also introduced complexity in distinguishing between similar codes. Coders must be diligent in ensuring that R10.819 is used appropriately and supported by clinical documentation.

ICD-9 vs ICD-10
