2025 ICD-10-CM code I12
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Circulatory system diseases - Hypertensive diseases Chapter 9: Diseases of the circulatory system (I00-I99) Feed
Hypertensive chronic kidney disease;this code indicates hypertension as the cause of chronic kidney disease.
Modifiers may apply to procedures performed in the context of managing this condition. Consult payer guidelines and coding manuals for appropriate modifier usage.
Medical necessity is established by the presence of hypertension as the causative factor for the chronic kidney disease. Documentation should clearly link the hypertension to the development and progression of the CKD.
Diagnosis and management of hypertension and chronic kidney disease, including monitoring blood pressure, kidney function (GFR/eGFR), and appropriate interventions such as medication management and lifestyle modifications.
In simple words: This code means high blood pressure has caused long-term kidney damage.The doctor needs to specify the severity of the kidney damage for accurate billing.
This ICD-10-CM code, I12, represents hypertensive chronic kidney disease.It signifies that hypertension is the underlying cause of the chronic kidney disease.The code encompasses various stages of CKD, requiring further specification (e.g., I12.9 for stages 1-4, I12.0 for stages 5-6) based on the patient's glomerular filtration rate (GFR) or estimated GFR (eGFR).Accurate staging is crucial for proper reimbursement and reflects the severity of the renal impairment.
Example 1: A 65-year-old male patient with a history of poorly controlled hypertension presents with elevated creatinine levels and reduced GFR, indicating stage 3 CKD.Code I12.9 is used to reflect hypertensive chronic kidney disease, stage 3., A 70-year-old female patient with long-standing hypertension develops end-stage renal disease (ESRD), requiring dialysis.Code I12.0 is appropriate, indicating hypertensive chronic kidney disease, stages 5-6., A 50-year-old patient with a history of hypertension is found to have early stage CKD (stage 1) during a routine checkup. Code I12.9 will be used to reflect hypertensive chronic kidney disease stage 1.
Medical history detailing hypertension,laboratory results (serum creatinine, GFR/eGFR,urine analysis),physician's assessment of kidney function, and any treatment plan for hypertension and CKD.
** The severity of the CKD should be specified using appropriate codes (I12.0, I12.9) based on the GFR/eGFR.
- Revenue Code: Revenue codes will vary based on the specific services provided and the payer.
- RVU: RVUs are not directly associated with ICD-10 codes; they are linked to CPT codes which represent procedures and services.The reimbursement for services related to this diagnosis will depend on the specific procedures performed and payer's fee schedule.
- Global Days: Not applicable to ICD-10 codes.
- Payment Status: Active
- Modifier TC rule: Not applicable to ICD-10 codes.
- Fee Schedule: Not applicable to ICD-10 codes. Reimbursement is determined by the procedures and services rendered, coded using CPT codes, and the payer's fee schedule.
