R85.7

Abnormal histological findings in specimens from digestive organs and abdominal cavity

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

Code Description

ICD-10 R85.7 is a billable code used to indicate a diagnosis of abnormal histological findings in specimens from digestive organs and abdominal cavity.

Key Diagnostic Point:

R85.7 is used to classify abnormal histological findings in specimens obtained from the digestive organs and abdominal cavity that do not fall under more specific categories. These findings may include atypical cellular changes, inflammation, or other histopathological abnormalities identified through biopsy or surgical specimens. Common causes of such findings can range from benign conditions like gastritis or colitis to malignant processes such as adenocarcinoma or lymphoma. The diagnosis often requires a thorough review of the patient's clinical history, presenting symptoms, and laboratory results, including imaging studies. Accurate coding is essential for proper treatment planning and reimbursement, as these findings can significantly impact patient management and outcomes.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of potential underlying conditions
  • Need for precise documentation of histological findings
  • Differentiation from similar codes
  • Potential for overlapping symptoms with other diagnoses

Audit Risk Factors

  • Inadequate documentation of histological findings
  • Failure to specify the site of the abnormality
  • Misclassification of benign versus malignant findings
  • Lack of correlation between clinical findings and coding

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Detailed clinical history, including symptoms and prior treatments, must be documented. Pathology reports should clearly describe the histological findings.

Common Clinical Scenarios

Patients presenting with abdominal pain, weight loss, or gastrointestinal bleeding may undergo biopsies leading to abnormal findings.

Billing Considerations

Ensure that the documentation reflects the clinical significance of the findings and any follow-up actions taken.

Emergency Medicine

Documentation Requirements

Acute care documentation must include the patient's presenting symptoms, any imaging or lab results, and the rationale for obtaining biopsies.

Common Clinical Scenarios

Patients with acute abdominal pain or gastrointestinal hemorrhage may require urgent biopsies.

Billing Considerations

In emergency settings, rapid documentation is crucial; ensure that all findings are accurately captured for coding.

Coding Guidelines

Inclusion Criteria

Use R85.7 When
  • Follow the official ICD
  • CM coding guidelines, ensuring that the code is used only when the histological findings are not classified elsewhere
  • Documentation must support the diagnosis and findings

Exclusion Criteria

Do NOT use R85.7 When
No specific exclusions found.

Clinical Scenario

Used when a biopsy is performed and histological findings are evaluated.

Documentation Requirements

Pathology report must include detailed findings and correlate with clinical history.

Specialty Considerations

Pathologists must ensure accurate reporting of findings to support coding.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of abnormal findings, improving the granularity of data for research and treatment planning. R85.7 provides a means to capture findings that do not fit neatly into other categories.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of abnormal findings, improving the granularity of data for research and treatment planning. R85.7 provides a means to capture findings that do not fit neatly into other categories.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of abnormal findings, improving the granularity of data for research and treatment planning. R85.7 provides a means to capture findings that do not fit neatly into other categories.
