Explore resources for accurate and efficient medical record keeping related to kidney injuries and bleeding.
Blood collection around the kidney, usually due to trauma.
Flank pain, bruising, tenderness, and possible signs of shock.
Trauma centers, emergency rooms, and operating rooms.
ICD-10 Code Families
Complete code families applicable to N28.89
When to use each related code
| Description | When to use |
|---|---|
| Blood collection around kidney | Trauma, surgery, bleeding disorders causing bleeding around kidney. Not for blood within kidney. |
| Kidney bleed within capsule | Subcapsular hematoma: blunt trauma, contained bleed within kidney capsule. Not for perirenal bleeds. |
| Kidney laceration | Kidney injury with parenchymal tear due to trauma. Not for contusions without laceration. |
Best-practice checklist
- ✓Document cause of perinephric hematoma (trauma, surgery, etc.)
- ✓Size and location of hematoma precisely documented using imaging reports
- ✓Signs/symptoms: flank pain, hematuria, hypotension documented
- ✓Labs: hemoglobin, hematocrit, coagulation studies results
- ✓Treatment plan: observation, intervention (if any) specified
Common pitfalls to avoid
Coding perinephric hematoma without documenting the cause (traumatic vs. spontaneous) leads to coding errors and claim denials.
Failing to document laterality (right, left, bilateral) for perinephric hematoma impacts coding specificity and reimbursement.
Distinguishing between iatrogenic (procedure-related) and non-iatrogenic hematomas is crucial for accurate coding and quality reporting.
Best-practice tips
- 01Document trauma mechanism for accurate ICD-10-CM S37.xxx coding.
- 02Clearly specify hematoma location (perinephric) in operative reports for CDI.
- 03Correlate imaging (CT/MRI) with clinical findings for compliant S37.xxx justification.
- 04Query physician for bleed source to ensure complete HCC coding compliance.
- 05Monitor renal function, document changes for accurate severity coding (N17.x).
Step-by-step checklist
- 1
Verify history of trauma, anticoagulant use, or bleeding disorder
- 2
Confirm flank pain, ecchymosis, and hypotension signs
- 3
Check imaging (CT scan) for perinephric fluid collection
- 4
Review labs for declining hemoglobin and hematocrit
- 5
Assess for signs of hemorrhagic shock and renal dysfunction
Ready-to-paste narrative
Patient presents with complaints consistent with perinephric hematoma, including flank pain, abdominal pain, and hematuria. Symptoms onset was [timeframe] and associated with [precipitating event, if any, e.g., trauma, anticoagulant therapy, interventional procedure, spontaneous bleed]. Review of systems reveals [positive findings related to pain, bleeding, urinary symptoms, or systemic effects e.g., dizziness, lightheadedness, nausea, vomiting]. Physical examination reveals [positive and pertinent negative findings e.g., flank tenderness, ecchymosis, palpable mass, stable vital signs]. Differential diagnosis includes renal trauma, renal cell carcinoma, renal infarction, retroperitoneal hemorrhage, and aortic aneurysm. Imaging studies, including [mention specific imaging like CT scan abdomen and pelvis with IV contrast, ultrasound], were ordered to evaluate for perinephric bleeding and assess the extent of the hematoma. Laboratory tests, including [mention specific labs like CBC, coagulation panel, urinalysis, BUN, creatinine], were ordered to evaluate for active bleeding, assess renal function, and identify any coagulopathy. Impression: Perinephric hematoma, likely secondary to [cause, e.g., blunt trauma, anticoagulant therapy]. Management plan includes [specific management plan, e.g., monitoring vital signs, serial imaging, pain management, correction of coagulopathy if present, urology consultation, surgical intervention if indicated]. Patient education provided regarding the diagnosis, treatment plan, and potential complications. Follow-up scheduled for [timeframe] to re-evaluate and assess response to treatment. Patient advised to return to the emergency department if symptoms worsen or new symptoms develop. ICD-10 code S37.01XA (Traumatic subcapsular or perinephric hematoma of right kidney with active bleeding) or S37.02XA (Traumatic subcapsular or perinephric hematoma of left kidney with active bleeding) may be applicable depending on laterality and presence of active bleeding; other codes may be necessary depending on etiology and complications.
