R84.1

Abnormal level of hormones in specimens from respiratory organs and thorax

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

Code Description

ICD-10 R84.1 is a billable code used to indicate a diagnosis of abnormal level of hormones in specimens from respiratory organs and thorax.

Key Diagnostic Point:

R84.1 refers to abnormal hormone levels detected in specimens obtained from the respiratory organs and thoracic region. Hormones such as catecholamines, cortisol, and others can be produced by tumors or other pathologies affecting the lungs and thorax. Symptoms may include unexplained weight changes, fatigue, or respiratory distress, depending on the specific hormone involved. Abnormal hormone levels can indicate conditions such as pheochromocytoma, Cushing's syndrome, or other endocrine disorders. Laboratory findings may include elevated levels of specific hormones in blood or urine tests, and imaging studies may reveal tumors or lesions in the thoracic cavity. Accurate diagnosis requires a thorough clinical evaluation, including patient history, physical examination, and targeted laboratory tests.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of hormones that can be involved
  • Need for specific laboratory tests to confirm abnormal levels
  • Potential overlap with other respiratory conditions
  • Variability in symptoms based on hormone type

Audit Risk Factors

  • Inadequate documentation of hormone levels
  • Failure to specify the respiratory organ involved
  • Misclassification of symptoms related to hormone abnormalities
  • Lack of correlation between clinical findings and lab results

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Detailed patient history, physical exam findings, and lab results must be documented to support the diagnosis.

Common Clinical Scenarios

Patients presenting with fatigue, weight changes, or respiratory symptoms requiring hormonal evaluation.

Billing Considerations

Consider the patient's overall endocrine function and any comorbid conditions that may affect hormone levels.

Emergency Medicine

Documentation Requirements

Acute care documentation must include vital signs, immediate lab results, and any interventions performed.

Common Clinical Scenarios

Patients with acute respiratory distress or hypertensive crises potentially related to abnormal hormone levels.

Billing Considerations

Rapid assessment and documentation are crucial in emergency settings to ensure appropriate coding.
