Our Coding & Quality Measures Series discusses how coding may adversely affect your quality statistics and bottom line. For this weeks tip, our Executive Director of Education, Patricia Maccariella-Hafey, RHIA, CDIP, CCS, CCS-P, CIRCC explores what happens to your Hypertension Admission Rate quality metric when a coder erroneously reports hypertension. Patricia also provides key takeaways and best practices.
Is your facility reporting the R29.7– ICD-10-CM code for the National Institute of Health Stroke Scale (NIHSS) on patients diagnosed with a stroke? If so, are coders reporting these codes correctly?
What is the Revised Stroke Mortality Measure?
The refined Stroke 30-day mortality measure (MORT-30-STK) is a statistic defined as death occurring within 30 days of a diagnosed stroke. The Centers for Medicare & Medicaid Services (CMS) publicly reports a 30-day hospital-level stroke mortality measure on Hospital Compare as part of the Inpatient Quality Reporting (IQR) program. Measurement of patient mortality allows for a broad view of quality of care that encompasses more than what can be captured by individual process-of-care measures. The goal of outcome measurement is to identify institutions whose performance is better or worse than would be expected based on their patient case mix, by risk adjusting for patients’ conditions at the time of hospital admission. The goal of reporting a stroke outcome measure is to improve patient outcomes by providing patients, physicians, and hospitals with information about hospital-level risk-standardized mortality rates (RSMRs) following hospitalization for acute ischemic stroke.
Hospitals will receive confidential reports for the revised stroke mortality measure in CY 2021 using claims data from October 2017 to June 2020. Results in these reports will not be publicly reported or used for payment determination. CMS will implement the revised stroke mortality measure in the FY 2023 payment determination using claims data from July 2018 to June 2021.
***Hospitals should include the ICD-10-CM code for the NIH Stroke Scale score on submitted claims. The NIH Stroke Scale included in claims should be the first NIH Stroke Scale score documented in the medical record after the patient’s arrival at the hospital. Hospitals should use a POA code of “Yes” to capture the initial NIH Stroke Scale and POA code(s) of “No” to capture the other scores if multiple scores are available.
The NIH Stroke Scale revision only applies to the Stroke MORTALITY measure.
What is the Issue with the NIH Stroke Scale Code?
The problem is that many hospitals have not been reporting the NIH Stroke Scale ICD-10-CM codes as the Official Guidelines for Coding and Reporting have stated reporting of the code is optional. Here is what guideline I. C. 18. i. NIHSS Stroke Scale states:
“The NIH stroke scale (NIHSS) codes (R29.7- -) can be used in conjunction with acute stroke codes
(I63) to identify the patient’s neurological status and the severity of the stroke. The stroke scale codes
should be sequenced after the acute stroke diagnosis code(s).
At a minimum, report the initial score documented. If desired, a facility may choose to capture
multiple stroke scale scores.
See Section I.B.14 for NIHSS stroke scale documentation by clinicians other than patient’s provider”
Since the guideline above states can be used, many coders are not reporting the R29.7- – code.
Coders should be educated on what the NIHSS is and where in the record they can find this information to assign the correct code.
NIH Stroke Scale scores range from 0 to 42, with higher values indicating more severe strokes. The NIHSS is a 15-item neurologic examination stroke scale used to evaluate the effect of acute cerebral infarction/stroke on the levels of consciousness, language, neglect, visual-field loss, extraocular movement, motor strength, ataxia, dysarthria, and sensory loss.
The ICD-10-CM code book index entry is NIHSS (National Institutes of Health Stroke Scale) score R29.7- The NIHSS stroke score can be assigned based on provider or other clinicians’ documentation.
A link is provided below for the criteria used in determining the NIH Stroke Scale score. Coders should not calculate the score as it is to be calculated clinically by the patient’s clinician.
Coding take Away: Always report the NIH Stroke Scale code (R29.7–) on cases with an acute stroke/infarction (I63). Failure to report the code R29.7- – correctly, or at all, will impact the 30-day Stroke Mortality Measure. This data collected from claims since July 2018 will impact reimbursement. It may be a good idea to audit all stroke cases to ensure the correct NIH Stroke Scale code is assigned. Work with the facility’s quality department in determining data reporting periods.

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.

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.

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).
Part 3: Clinical Indicators for Acute Kidney Injury/Failure | AKI Series
