How to Document and Code for Hypertensive Illnesses in ICD-10

When assigning a diagnosis code for HTN or hypertension, there’s a presumed causal connection between heart involvement and hypertension, and between kidney involvement and hypertension.

These conditions must be coded as associated even in the nonappearance of provider documentation openly linking them, if not the documentation states the condition is not related.

ICD 10 Code for High Blood Pressure with Heart Illness

Hypertension or HTN with heart diseases categorized to 150 must be allocated to a code from type I11, hypertensive heart disease. An extra code from class 150, which is heart failure, must be reported to know the kind of heart failure in patients that have heart failure. When the provider has documented has specifically a different cause, similar hear conditions with hypertension are coded singly. These must be sequenced by the conditions of the encounter or admission. Like for instance, the provider recorded exacerbated CHF or chronic heart failure and HTN.

Hypertensive Chronic Kidney Disease

Why is it necessary to differentiate icd 10 code for high blood pressure from other codes? Codes from I12 category, chronic hypertensive illness, must be assigned if both hypertension and a situation classifiable to N18 category, CKD or chronic kidney disease, are present. Chronic Kidney Disease shouldn’t be coded as HTN or hypertensive if the doctor has documented specifically a different cause. The right coded from N18 category must be utilized as a secondary code with a system from N12 category to determine the level of CKD.

When you have hypertensive CKD and ARF or acute renal failure, an extra code for the ARF is needed. Like for instance, the provider codes hypertension and stage 2 kidney disorder. Hypertensive CKD illness with stage one through stage four CKD or not specified CKD and N18.3, CKD, stage III (moderate).

Like for instance, the provider documents hypertension, CHG as well as stage 3 kidney illnesses. Hypertensive heart and CKD with stage one through 4 CKD, and heart failure or not specified CKD, congestive, systolic, heart failure, acute as well as CKD, stage III moderate.

Secondary Hypertension Coding

Even if the focus of this article has been essential HTN, which include comorbidities of chronic kidney disease and heart failure, there might be some people in the primary care setting who are experiencing HTN secondary to other illness states. In these conditions, providers are not able to utilize the ICD-10 codes mentioned above. Rather utilize these codes:

  • 0, Renovascular hypertension
  • 1, Hypertension secondary to other renal disorders
  • 2, Hypertension secondary to endocrine disorders
  • 8, Other secondary hypertension
  • 9, Secondary hypertension, unspecified.

These 5 secondary hypertension codes need that you code the fundamental condition as well. ICD10 usually allows either the fundamental condition or the secondary code to be recorded first. It depends on the reason for the one meet. The exemption to this is I15.8, other secondary HTN. This is because this is an “other” code, the “other” disease or condition should be documented first.

Hypertensive Hear and CKD or Chronic Kidney Disease

The codes in I13 category, hypertensive heart, and CKD or chronic kidney diseases, are permutation codes which take account of hypertension HTN, heart illness as well as chronic kidney disease, and must be utilized when there’s hypertension with both kidney and heart involvement.

When heart failure is at hand, and extra code from I50 category must be reported to know or determine the kind of heart failure. The right code from N18 category, chronic kidney disease or CKD, must be utilized as a secondary code with a code from I13 category to know the level of CKD or chronic kidney disease.

For HTN with other diseases not mentioned above, provider documentation should link the conditions or diseases to record or code them as related.

Tobacco Use/ Exposure in People with Hypertensive Conditions

Use of tobacco or exposure in people suffering from hypertensive illnesses, all the HTN codes needs an extra ICD-10 code when the patient is a previous or current user of tobacco. In some conditions, you would utilize these following codes and not simply code it as icd 10 code for high blood pressure:

  • F17, Nicotine dependence
  • 20, Unspecified
  • 21, Cigar
  • 22 Grinding tobacco
  • 29, other products made of tobacco

Each of the categories mentioned has a needed six character such as 0 or uncomplicated, 1 or in remission, 3 or withdrawal, as well as 8, with another particular nicotine-induced disarray.

The ICD-10 manual partly explains the disparity between nicotine dependence, cigars, in remission and personal history of nicotine addiction. It shows that a personal history code must be utilized when the condition of the patient is no longer exists and isn’t being handled but has the chance to recur, and so, might need regular monitoring. The remission code is applicable once a patient is keenly utilizing a product to put an end to smoking. If the patient has ended using tobacco products, it’s up to the provider to identify if the status of the patient would go from in remission to the personal history.

Adapting to ICD-10

Once this overture to the new HTN codes has augmented your blood pressure, you need to stop, relax and inhale. ICD-10 coding is indeed a huge adjustment. However, it will get more straightforward and more comfortable with practice and with time, as well.

Conclusion

These are the essential steps in documenting icd 10 code for high blood pressure. This is vital in determining the level of HTN or hypertension.
