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.
PQI 07: Hypertension Admission Rate
Did you know that by coding hypertension with associated CKD correctly along with any surgical dialysis access creation on patients admitted with hypertension, will keep the case out of the AHRQ PQI #07: Hypertension Admission Rate quality measure?
The Prevention Quality Indicators (PQIs) are a set of measures that can be used with hospital inpatient discharge data to identify quality of care for “ambulatory care sensitive conditions.” These are conditions for which good outpatient care can potentially prevent the need for hospitalization or for which early intervention can prevent complications or more severe disease. The PQIs are population based and adjusted for covariates. With high-quality, community-based primary care, hospitalization for these illnesses often can be avoided. Because the PQIs are calculated using readily available hospital administrative data, they are an easy-to-use and inexpensive screening tool.
PQI 07 states: “Admissions with a principal diagnosis of hypertension per 100,000 population, ages 18 years and older. Excludes kidney disease combined with dialysis access procedure admissions, cardiac procedure admissions, obstetric admissions, and transfers from other institutions.”
Takeaways
Let’s say a coder erroneously reports I10, Hypertension NOS, for hypertension with CKD stage IV instead of I12.9, Hypertensive CKD with stage I-IV and N18.4, CKD stage 4. The coder also forgets to assign or correctly code creation of an AV fistula such as 03180ZD, Bypass Left Brachial Artery to Upper Arm Vein, Open Approach, in anticipation of future dialysis on this case. This can cause the case to hit the PQI #07 quality measure! Also, if the diagnoses codes are coded correctly, however the AV fistula creation code is incorrect, the case may also hit the PQI #07 quality measure.
There is also a list of cardiac procedures that can exclude the case from this measure.
There are other exclusions to this measure such as an incorrect UB04 admission source (2-other hospital and 3-another facility, including long-term care excludes the case) or point of origin code (POO) 4-transfer from a hospital, 5-transfer from an SNF or ICF, and 6-Trans from another health care facility, which exclude the case. Please see the references below for more information.

HIA Launches Buddy Up Program for New Hires
This past year, HIA implemented “Buddy Up,” a program designed to help the new hire have a smooth transition into their new HIA roles with the assistance of a “buddy.” What is a Buddy? The Buddy is simply a peer who can guide the new hire in order to make them feel more comfortable. We are very proud of this program and have many success stories that we would like to share. Take a look at the wonderful feedback we have received below.
Part 4: Spinal Fusion Coding — Identifying the Column Being Fused
In Part 3, we focused on determining the level of the fusion(s) and how to determine the number of vertebrae fused. In Part 4, we are going to focus on identifying which column is being fused (anterior, posterior or both).
Part 3: Spinal Fusion Coding — Determine the Level(s) or Region of Fusion and Number of Vertebrae Fused
In Part 1, we learned the diagnoses associated with the need for spinal fusions, and in Part 2 the need to identify if the fusion is an initial or refusion of the vertebrae. In Part 3, we are going to focus on determining the level(s) of fusion, as well as the number of vertebrae fused.
Part 2: Spinal Fusion Coding — Initial Fusion or Refusion
In Part 2, we are going to look at the differences between initial fusion and a refusion. In ICD-9, there were specific codes to show if the fusion was an initial fusion, or if it was a refusion. In ICD-10-PCS, initial fusions and refusion procedures are coded to the same root operation “fusion.”
Part 1: Spinal Fusion Coding — Diagnoses Responsible
This is Part 1 of a 14 part series focusing on education for spinal fusions. Spinal fusion coding is a tough job for coders. There are so many diseases/disorders that result in the need for spinal fusion, and even more choices in reporting the ICD-10-PCS codes.
What’s the Best Defense? A Good Offense
The official definition from the Centers for Medicare & Medicaid Services (CMS) states that a Medicare overpayment is a payment that exceeds amounts properly payable under Medicare statutes and regulations. When Medicare identifies an overpayment, the amount becomes a debt you owe the Federal government.
Query Tip: Writing a Query Question – Simple and Concise is the Key
The question asked in a physician query may be the most important element of the document. Query questions need to be as simple and concise as possible. The physician should have no doubt what the coder is asking.
Coding Tip: Coding Complications of Transplanted Organs
Coding complications of transplanted organs has always been a coding dilemma. With the implementation of ICD-10-CM that didn’t change. However, coders have multiple directives to help in determining what a complication of the transplant is vs. non-transplant conditions and diseases.
Find Your Routine: Take Advantage of Educational Opportunities
We interviewed our most productive coders, reviewers and members of our education team, asking them what steps they take to find a rhythm that works for them. This week, we talked with Beth Martilik, MA, RHIA, CDIP, CCS, Assistant Director of Education, about the steps she takes to find her routine.
Coding Tip: Atrial Fibrillation
With the implementation of ICD-10-CM came more codes for reporting many different conditions and diseases, and atrial fibrillation is one of those. For many years there was only one code available for reporting this condition, even when the physician further specified the type of atrial fibrillation that the patient had. In ICD-10-CM, there are four codes to report atrial fibrillation.
Coder Q&A with Pat Macc: Mucoid Casts and Mucus Plugs
We have a case where the physician removes mucoid casts found during bronchoscopy. We have also seen mucus plugs removed during bronchoscopy. The MD performs bronchial washings then removes a large amount of tenacious and thick mucoid casts via bronchoscopy. Is this coded drainage, extirpation or excision? What body part is used?
Query Tip: How to Be More Efficient
The key to making the query process more efficient is to look for words or documentation while reviewing the record that may signal a potential query opportunity and to note the finding at that time. By the time a coder reaches the end of a record, documentation may have been found to eliminate the need for the query.
Coder Q&A with Pat Macc: Metastatic Cancer
Question: This patient is noted to have “Lymphangitic carcinomatosis of lungs with mediastinal lymph nodes.” How would I code the diagnosis? Would I code metastatic cancer to the lung (C78.01) or metastatic cancer to the lymph nodes (C77.1)?
Coder Q&A with Pat Macc: Collapse of an Endograft
This would be considered a “mechanical” complication of the stent graft since the MD states it is a fracture of the endograft and it is folded over on itself. I would change T82.898A TO T82.598A for Other mechanical complication of other cardiac and vascular devices and implants, initial encounter. I did not use “displacement” because the surgeon did not state that the graft was displaced, only that it collapsed upon itself causing obstruction.
Find Your Routine: Be Flexible, Not Frustrated
We interviewed our most productive coders and reviewers, asking them what steps they take to find a rhythm that works for them. This week, we talked with Valerie Abney, CDIP, RHIT, CCS, about the steps she takes to find her routine.
Coding Tip: Periprosthetic Fracture Reporting and Sequencing
Osteoporosis alone is responsible for over a million fractures every year. Stress fractures are not as common but they do occur. There are more than 1 million total joint replacements in the U.S. each year, so there was a need to create codes for injuries that occur around or near the prosthesis. These are called “periprosthetic” fractures.
OIG Takes Notice of Coding Errors
Back in April, the Office of the Inspector General (OIG) published a report detailing its findings from a review of two groups of high-risk diagnosis codes, acute stroke and major depressive disorder. The objective was to determine whether selected diagnosis codes submitted to the Centers for Medicare and Medicaid Services for use in CMS’s risk adjustment program complied with Federal requirements.
Coder Q&A with Pat Macc: Coding for Newborn
There seems to be differences of opinions on the issue of a 40w0day gestation Can you clarify if P08.21 should be assigned for 40w0day infant or if it would not be assigned unless the infant’s gestation age was 40w1day or greater?
Query Tip: When to Query for Sepsis
Coders may find situations where a patient is documented as meeting SIRS or sepsis criteria, or has some clinical indicators reflective of possible sepsis, but the physician never documents sepsis as a diagnosis. Should the coder always query for sepsis in these instances?
