Range Overview

high priority

The ICD-10 code range F50-F59, 'Behavioral syndromes associated with physiological disturbances and physical factors', is used to document conditions where physical health issues are significantly affected by behavioral factors. This includes eating disorders, sleep disorders, sexual dysfunction, and other conditions where physiological disturbances are linked to mental and behavioral patterns. These codes are used across various medical specialties, including psychiatry, neurology, and primary care.

Key Usage Points:

  • •F50-F59 codes are used when a patient's physical health is significantly affected by behavioral factors.
  • •These codes cover a wide range of conditions, including eating disorders, sleep disorders, and sexual dysfunction.
  • •F50-F59 codes are used across various medical specialties, including psychiatry, neurology, and primary care.
  • •Documentation should clearly link the physical disturbance to the behavioral syndrome.
  • •Always code to the highest level of specificity within the F50-F59 range.

Coding Guidelines

When to Use:

  • ✓When a patient has an eating disorder that is causing physical health issues.
  • ✓When a patient has a sleep disorder that is significantly affecting their daily life.
  • ✓When a patient has sexual dysfunction that is linked to a behavioral syndrome.
  • ✓When a patient's physical health issue is significantly affected by a mental or behavioral disorder.
  • ✓When a patient has a mental or behavioral disorder that is causing a physical disturbance.

When NOT to Use:

  • ✗When a patient has a physical health issue that is not significantly affected by a behavioral syndrome.
  • ✗When a patient has a mental or behavioral disorder that is not causing a physical disturbance.
  • ✗When a patient's condition can be better described by a code outside the F50-F59 range.
  • ✗When a patient's condition is due to substance abuse or dependence.
  • ✗When a patient's condition is due to a neurological disorder.

Code Exclusions

Always verify exclusions with the latest ICD-10 guidelines and the patient's medical record.

Documentation Requirements

Documentation for the F50-F59 range should clearly link the patient's physical disturbance to a behavioral syndrome. This includes a detailed description of the patient's symptoms, the impact of the condition on the patient's daily life, and any relevant medical history. Documentation should also include any diagnostic tests or treatments that have been performed, as well as the patient's response to treatment.

Clinical Information:

  • •Detailed description of the patient's symptoms
  • •Impact of the condition on the patient's daily life
  • •Relevant medical history
  • •Diagnostic tests or treatments performed
  • •Patient's response to treatment

Supporting Evidence:

  • •Clinical notes
  • •Diagnostic test results
  • •Treatment records
  • •Patient self-reports
Good Documentation Example:

Patient has been diagnosed with anorexia nervosa. She has lost significant weight and is experiencing physical health issues as a result. She has a history of body image issues and has been receiving counseling.

Poor Documentation Example:

Patient has lost weight.

Common Documentation Errors:

  • âš Not linking the physical disturbance to a behavioral syndrome
  • âš Not documenting the impact of the condition on the patient's daily life
  • âš Not including relevant medical history
  • âš Not documenting diagnostic tests or treatments performed
  • âš Not documenting the patient's response to treatment
