There are now codes to describe hypertensive crisis in ICD-10-CM category I16, Hypertensive Crisis. Coders are now able to differentiate coding of hypertensive urgency (I16.0), hypertensive emergency (I16.1), and hypertensive crisis, unspecified (I16.9). This allows tracking of patients that require immediate treatment for clinically significant hypertension. Accelerated or malignant hypertension would not be coded in this category and would be reported with a code from category I10-I15.
Hypertensive crisis definition:
- Hypertensive crisis—severe rapid increase in blood pressure with the systolic (top number) of 180 (mm Hg) or higher or a diastolic (bottom number) of 120 (mm Hg) or higher. This can lead to damaged blood vessels. The blood vessels become inflamed and can leak fluid or blood. This can result in the heart not being able to pump the blood effectively. When patients present with hypertensive crisis, immediate evaluation is needed to assess the organ function and rule out/in any organ damage and then determine the appropriate treatment. A patient without a diagnosis of hypertension may have a hypertensive crisis with a lower blood pressure documented (lower than 180 systolic or 120 diastolic).
Hypertensive crisis is divided into two categories:
- Urgent—extremely high blood pressure. The patient is not suspected to have any damage to organs
- Emergency—extremely high blood pressure which has caused damage to organs
There are many causes for hypertensive crisis and they can include:
- Medication noncompliance or medication reaction/interaction with other drugs
- Stroke, MI, heart failure, renal failure
- Abdominal aorta rupture
- Eclampsia during pregnancy
Signs and symptoms of hypertensive crisis may include:
- Severe chest pain/Shortness of breath
- Severe headache that may be associated with blurred vision and confusion and/or seizures
- N&V
- Unresponsiveness
- Nose bleed
- Marked anxiety
- Swelling/edema
Hypertensive crisis is uncommon in children but if a sudden severe increase in a child’s blood pressure occurs they will require immediate intervention to prevent harmful consequences.
When the documentation supports a code from the category I16, Hypertensive crisis, the sequencing of codes is based on the circumstances of admission/reason for the admission/encounter. The coder would also code any hypertensive disease (I10-I15).

Coding Tip: Reporting “Flash” Pulmonary Edema
Acute pulmonary edema is the rapid accumulation of fluid within the tissue and space around the air sacs of the lung (lung interstitium). When this fluid collects in the air sacs in the lungs it is difficult to breathe. Acute pulmonary edema occurs suddenly and is life threatening.
Client S: $556 increase/record reviewed
“Client S” is a small, not-for-profit, 40 bed micro-hospital in the Southeast. HIA performed a 65-record review this year for Client S and found an opportunity with 15 of them. 9 had an increased reimbursement with a total of $43,228 found.
Coding Tip: Glasgow Coma Scale Coding OCG Update for FY2021
The coma scale codes (R40.2-) can be used in conjunction with traumatic brain injury codes, acute cerebrovascular disease or sequelae of cerebrovascular disease codes. These codes are primarily for use by trauma registries, but they may be used in any setting where this information is collected. The coma scale may also be used to assess the status of the central nervous system for other non-trauma conditions, such as monitoring patients in the intensive care unit regardless of medical condition.
Coding Tip: Cardiac Arrest and Cardiac Shock
In the past, there had been an Excludes1 note at I46.- Cardiac arrest that excluded R57.0, Cardiac shock. HIA had also received a letter from AHA on a case in the past that had stated that only I46.- Cardiac arrest would be coded if both were documented. In addition, the Third Quarter Coding Clinic page 26 had a similar case that asked if both could be coded, and AHA had instructed that only I46.9, cardiac arrest, cause unspecified would be coded if both were documented and that the CDC would be looking at possible revision to the Excludes1 note.
Client X: Let’s Talk Numbers
A higher CMI corresponds to increased consumption of resources and increased cost of patient care, resulting in increased reimbursement to the facility from government and private payers, like CMS. We know that documentation directly impacts coding.
Coding Tip: Endarterectomy During Coronary Artery Bypass
Lately we have seen several cases where the endarterectomy was assigned along with the coronary artery bypass (CABG) procedure when being performed on the same vessel to facilitate the CABG. A coronary artery endarterectomy is not always performed during a CABG procedure, so when it is performed it becomes confusing as to whether to code it separately or not.
Coding Tip: Update – Coding COVID-19 When the Test is Negative
Assign code Z20.828, “Contact with and (suspected) exposure to other viral communicable diseases” for all patients who are tested for COVID-19 and the results are negative, regardless of symptoms, no symptoms, exposure or not as we are in a pandemic.
New ICD-10-PCS Procedure Codes for COVID-19
The Centers for Medicare & Medicaid Services (CMS) announced new procedure codes for treatments of COVID-19 – effective as of August 1, 2020. Among the new codes are Section X New Technology codes for the introduction or infusion of therapeutics including Remdesivir, Sarilumab, Tocilizumab, transfusion of convalescent plasma, as well as introduction of any other or new therapeutic substances for the treatment of COVID-19.
New Rule Helps Medicare ACOs During COVID-19 Pandemic
One common element in many value-based programs is risk adjustment using Hierarchical Condition Categories (HCCs) to create a Risk Adjustment Factor (RAF) score. This method ranks diagnoses into categories that represent conditions with similar cost patterns.
Part 5: Reasons for AKI Denials and Prevention | AKI Series
Why are so many AKI records being denied? It’s hard to give one answer for why so many AKI records are being denied lately, but most appear to be due to the multiple sets of criteria available for use in determining if a patient has AKI, as well as physician documentation. As stated in Part 3 of this series, there are three main criteria/classifications used to diagnose AKI.
Part 4: Is Documentation Present to Report Acute Kidney Injury/Failure? | AKI Series
In previous parts of this series we looked at the definitions of AKI/ARF, causes, coding and sequencing, and the common clinical indicators that patients present with that are diagnosed with this condition. In Part 4, we will look at the documentation that should be present to report the diagnosis without fear of denial, as well as when a query is needed to clarify the diagnosis.
Coding Tip: Z Code Reporting for COVID-19
If the facility does a COVID-19 test, and test is negative, do I need a diagnosis code. The answer is yes, you will report a Z-code. The Z-code depends on the record documentation and circumstances of testing. For any patient receiving a COVID-19 test, if negative, there MUST e a Z-code to describe why the test was taken. (Test negative for COVID-19 and MD does not override negative results).
FY2021 Proposed Rule and Code Changes Highlights
The FY2021 IPPS Proposed Rule is out and here are some highlights from it regarding ICD-10 Code proposals. We will know if these changes are permanent after the public comment period is over on July 10, 2020 and CMS prepares the Final Rule, usually out by August 1.
Part 2: Specificity Coding of Acute Kidney Injury (AKI) and Sequencing | AKI Series
As discussed in Part 1 of this series, AKI/ARF is a common diagnosis that coders see daily. In Part 2, we are going to focus on the different types/specificity of AKI/ARF. We’ll learn what they mean, as well as how to code the diagnosis.
Part 1: What is Acute Kidney Injury (AKI)? | AKI Series
This is part 1 in a series focused on coding of acute kidney injury (AKI) and/or acute renal failure (ARF). AKI/ARF is reported often, but is also one of the most common diagnosis found in denials.
Coding Tip: Covid-19 Diagnosis Coding Common Scenarios
With the proliferation of COVID-19 cases, we thought we would put together a quick reference listing of some of the common scenarios that coders have asked about. As with all coding, coders should follow Official Guidelines for Coding and Reporting and the COVD-19 Frequently Asked Questions document by the AHA.
Reporting Telehealth Services During the COVID-19 Emergency
Effective March 1, Medicare will pay physicians for telehealth services at the same rate as in-person visits for all diagnoses, not just services related to COVID-19. This great for providers whose patients are reluctant to visit the office.
Coding Tip: What is Single Path Coding?
The biggest reasons why some hospital systems are moving to single path coding is to eliminate duplicative processes and to optimize productivity. In addition, costs are reduced when only one coder “touches” the record and completes both types of coding.
