Diseases of the genitourinary system
This chapter covers ICD-10-CM codes in the range N00-N99 for diseases of the genitourinary system. Includes diseases of the genitourinary system such as kidney disease, urinary disorders, and disorders of male/female genital organs.
Chapter Overview
Key Statistics
- •Contains 11 categories and 84 total codes
- •Includes 66 billable codes and 18 non-billable codes
- •Chapter range: N00-N99
Clinical Relevance
Covers kidney disease, urinary tract infections, and reproductive system disorders. Important for nephrology, urology, and gynecology.
Documentation Requirements
Requires kidney function staging, organism identification for infections, and anatomical site specification.
Special Considerations
Chronic kidney disease requires stage documentation. UTI coding needs organism and site specificity.
Categories in this Chapter
Glomerular diseases
Renal tubulo-interstitial diseases
Acute kidney failure and chronic kidney disease
Urolithiasis
Other disorders of kidney and ureter
Other diseases of the urinary system
Diseases of male genital organs
Disorders of breast
Inflammatory diseases of female pelvic organs
Noninflammatory disorders of female genital tract
Intraoperative and postprocedural complications and disorders of genitourinary system
Chapter-Specific Coding Guidelines
General Guidelines for Diseases of the genitourinary system:
- Follow standard ICD-10-CM coding principles for diseases of the genitourinary system
- Document the most specific diagnosis supported by the medical record
- Use additional codes for manifestations, complications, or associated conditions
- Ensure proper sequencing based on the reason for the encounter
Documentation Requirements:
- •Specific condition or disease process
- •Acute versus chronic status when applicable
- •Severity or stage when documented
- •Associated symptoms or complications
- •Treatment response and current status
Sequencing Rules:
- Principal diagnosis should reflect the main reason for the encounter
- Sequence complications according to treatment focus
- Use appropriate combination codes when available
- Follow chapter-specific sequencing guidelines
When to Use:
- ✓For conditions classified in the N00-N99 range
- ✓When the condition is the primary focus of care
- ✓During active treatment or monitoring
- ✓For documented complications of the condition
When NOT to Use:
- ✗For personal history without current manifestations
- ✗During screening encounters without findings
- ✗For conditions better classified elsewhere
- ✗When condition is ruled out or suspected only
Special Considerations:
- ⚠Review chapter-specific coding guidelines
- ⚠Consider combination codes before multiple codes
- ⚠Document functional impact when relevant
- ⚠Use external cause codes when applicable
Version Updates

Frequently Asked Questions
What are the key considerations when coding diseases of the genitourinary system?
Focus on specific diagnosis documentation, proper sequencing, and use of additional codes for complications or manifestations related to diseases of the genitourinary system.
How do I determine the most appropriate code within this chapter?
Review the medical documentation for the most specific diagnosis, check for combination codes, and follow the ICD-10-CM guidelines for this chapter.
When should I use additional codes?
Use additional codes for manifestations, complications, external causes, or other conditions that affect patient care during the encounter.
