ICD 10 Code I12.9

Hypertensive chronic kidney disease with stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease

2017 Billable/Specific Code

  • I12.9 is a billable ICD-10 medical codes that provide a detailed representation of a patient's conditions or diagnoses.
  • ICD-10-CM codes are used for a variety of purposes, including statistics and for billing and claims reimbursement.
  • This is the American ICD 10 CM Version Of I12.9 allows for the capture of data regarding signs, symptoms, risk factors and comorbidities to better describe the clinical issue overall.

ICD 10 Official Documentation Guidelines For I12.9

  • Chapter 9
    Hypertension
    Hypertension The classification presumes a causal relationship between hypertension and heart involvement and between hypertension and kidney involvement, as the two conditions are linked by the term “with” in the Alphabetic Index. These conditions should be coded as related even in the absence of provider documentation explicitly linking them, unless the documentation clearly states the conditions are unrelated. For hypertension and conditions not specifically linked by relational terms such as “with,” “associated with” or “due to” in the classification, provider documentation must link the conditions in order to code them as related.
  • Chapter 9
    Hypertensive Chronic Kidney Disease
    2) Hypertensive Chronic Kidney Disease Assign codes from category I12, Hypertensive chronic kidney disease, when both hypertension and a condition classifiable to category N18, Chronic kidney disease (CKD), are present. CKD should not be coded as hypertensive if the physician has specifically documented a different cause. The appropriate code from category N18 should be used as a secondary code with a code from category I12 to identify the stage of chronic kidney disease. See Section I.C.14. Chronic kidney disease. If a patient has hypertensive chronic kidney disease and acute renal failure, an additional code for the acute renal failure is required.
  • Chapter 9
    Hypertensive Heart and Chronic Kidney Disease
    3) Hypertensive Heart and Chronic Kidney Disease Assign codes from combination category I13, Hypertensive heart and chronic kidney disease, when there is hypertension with both heart and kidney involvement. If heart failure is present, assign an additional code from category I50 to identify the type of heart failure. The appropriate code from category N18, Chronic kidney disease, should be used as a secondary code with a code from category I13 to identify the stage of chronic kidney disease. See Section I.C.14. Chronic kidney disease. The codes in category I13, Hypertensive heart and chronic kidney disease, are combination codes that include hypertension, heart disease and chronic kidney disease. The Includes note at I13 specifies that the conditions included at I11 and I12 are included together in I13. If a patient has hypertension, heart disease and chronic kidney disease, then a code from I13 should be used, not individual codes for hypertension, heart disease and chronic kidney disease, or codes from I11 or I12. For patients with both acute renal failure and chronic kidney disease, an additional code for acute renal failure is required.
  • Chapter 9
    Hypertensive Retinopathy
    5) Hypertensive Retinopathy Subcategory H35.0, Background retinopathy and retinal vascular changes, should be used with a code from category I10 – I15, Hypertensive disease to include the systemic hypertension. The sequencing is based on the reason for the encounter.
  • Chapter 9
    Hypertension, Controlled
    8) Hypertension, Controlled This diagnostic statement usually refers to an existing state of hypertension under control by therapy. Assign the appropriate code from categories I10-I15, Hypertensive diseases.
  • Chapter 9
    Hypertension, Uncontrolled
    9) Hypertension, Uncontrolled Uncontrolled hypertension may refer to untreated hypertension or hypertension not responding to current therapeutic regimen. In either case, assign the appropriate code from categories I10I15, Hypertensive diseases.
  • Chapter 9
    Hypertensive Crisis
    10) Hypertensive Crisis Assign a code from category I16, Hypertensive crisis, for documented hypertensive urgency, hypertensive emergency or unspecified hypertensive crisis. Code also any identified hypertensive disease (I10-I15). The sequencing is based on the reason for the encounter.
  • Chapter 14
    Chronic kidney disease
    a. Chronic kidney disease 1) Stages of chronic kidney disease (CKD) The ICD-10-CM classifies CKD based on severity. The severity of CKD is designated by stages 1-5. Stage 2, code N18.2, equates to mild CKD; stage 3, code N18.3, equates to moderate CKD; and stage 4, code N18.4, equates to severe CKD. Code N18.6, End stage renal disease (ESRD), is assigned when the provider has documented end-stage-renal disease (ESRD). If both a stage of CKD and ESRD are documented, assign code N18.6 only.
  • Chapter 14
    Chronic kidney disease with other conditions
    3) Chronic kidney disease with other conditions Patients with CKD may also suffer from other serious conditions, most commonly diabetes mellitus and hypertension. The sequencing of the CKD code in relationship to codes for other contributing conditions is based on the conventions in the Tabular List. See I.C.9. Hypertensive chronic kidney disease. See I.C.19. Chronic kidney disease and kidney transplant complications.
