HCC Risk Adjustment Status (CMS-HCC V28)
| Attribute | Status |
|---|---|
| HCC Category | Not assigned to any HCC category |
| RAF Score Impact | None - does not contribute to risk adjustment |
| CMS-HCC Model | V28 (Fully implemented 2026) |
| Risk Adjustment | No risk adjustment value |
HCC Context for 2026
- CMS-HCC Model V28 is fully implemented in 2026
- N32.89 does NOT map to any HCC category
- This code will not contribute to the patient’s Risk Adjustment Factor (RAF) score
- V28 reduced the number of diagnosis codes that map to HCCs from 9,797 to 7,770
- Genitourinary conditions generally have limited HCC representation unless associated with chronic kidney disease or ESRD
MS-DRG Mapping (Inpatient Hospital)
N32.89 maps to the following Medicare Severity Diagnosis-Related Groups:
| MS-DRG | Description | MDC | Relative Weight (v43.0) |
|---|---|---|---|
| 698 | Other kidney and urinary tract diagnoses with MCC | 11 | 1.6544 |
| 699 | Other kidney and urinary tract diagnoses with CC | 11 | 1.0150 |
| 700 | Other kidney and urinary tract diagnoses without CC/MCC | 11 | 0.6899 |
MDC 11: Diseases & Disorders of the Kidney & Urinary Tract
CC/MCC Status
- N32.89 alone does not qualify as a CC (Complication/Comorbidity) or MCC (Major Complication/Comorbidity)
- However, when paired with other qualifying conditions, it can contribute to the overall DRG assignment
- Final DRG assignment depends on:
- Principal diagnosis
- Secondary diagnoses with CC/MCC status
- Procedures performed
- Patient demographics

Coding Guidelines & Best Practices
Documentation Requirements
For accurate coding with N32.89, ensure documentation includes:
- Specific bladder disorder - Clearly identify which condition (hemorrhage, hypertrophy, calcification, contraction, etc.)
- Etiology - Document cause if known (infection, radiation, surgery, idiopathic)
- Chronicity - Indicate if acute or chronic condition
- Severity - Document extent of condition when applicable
- Associated symptoms - Pain, frequency, urgency, hematuria, etc.
- Diagnostic findings - Cystoscopy results, imaging findings, lab results
When to Use N32.89
✅ Appropriate Use:
- Bladder hemorrhage not due to trauma or malignancy
- Bladder hypertrophy from chronic obstruction
- Calcified bladder from chronic infection or schistosomiasis
- Contracted bladder from radiation cystitis or tuberculosis
- Bladder fibrosis from chronic inflammation
- Bladder ulceration (Hunner’s ulcer would use N30.10 for interstitial cystitis)
- Bladder trabeculation from chronic outlet obstruction
- Nontraumatic bladder rupture
❌ Do NOT Use N32.89 When:
- Bladder stones present - use N21.0 instead
- Female cystocele - use N81.1- series
- Overactive bladder - use N32.81 instead
- Bladder cancer - use appropriate C67.- code
- Traumatic bladder injury - use S37.2- series
- Interstitial cystitis - use N30.1- series
- Unspecified bladder disorder - use N32.9 instead
Coding Tips
- Specificity matters - If a more specific code exists, use it instead of N32.89
- Code all manifestations - If bladder disorder is due to underlying condition, code both
- Laterality - Bladder codes generally do not require laterality
- Sequencing - Code the underlying condition first if bladder disorder is secondary
- HCC capture - N32.89 does not contribute to HCC/RAF scores; focus on documenting comorbidities that do
Clinical Coding Examples

Quality Measures & Reporting
MIPS/QPP Considerations
- N32.89 may be relevant for urology-specific quality measures
- Document thoroughly to support medical necessity for procedures
- Consider impact on patient risk stratification (though not HCC)
Clinical Documentation Improvement (CDI)
Query opportunities when N32.89 is documented:
- Specify type of bladder disorder (hemorrhage, hypertrophy, calcification, contraction)
- Document etiology (radiation, infection, obstruction, idiopathic)
- Clarify acuity (acute vs. chronic)
- Identify associated complications
- Link to underlying conditions when applicable
Common Denial Reasons & How to Avoid
| Denial Reason | Prevention Strategy |
|---|---|
| Medical necessity not established | Document symptoms, diagnostic findings, and treatment rationale |
| More specific code available | Review full code set before selecting N32.89 |
| Duplicate coding | Ensure not coding both N32.89 and more specific bladder code |
| Excludes note violation | Review Type 1 and Type 2 excludes before finalizing codes |
| Insufficient documentation | Ensure operative reports support diagnosis coded |
