This is the next most common DRG with recommendations found in HIA reviews in 2021. Just to recap, HIA reviewed almost 50,000 inpatient records and over half a million codes in 2021. We will look at the top DRG’s with recommendations and see what can be done to prevent DRG changes going forward. Each coding tidbit will contain some tips for coding within the DRG or diagnosis area.
#6: DRG 793—Full term neonate with major problems
And DRG 794—Neonate with other significant problems
DRG 793 (Full term neonate with major problems) and DRG 794 (Neonate with other significant problems) are reported together for this tidbit since they were very close and very similar. The coding rules and guidelines for these two DRG’s are the same so we will look at these together.
Records reviewed: 1012
DRG recommended changes: 137
Accuracy of DRG 783/784: 85.28%
Thinking that coding a newborn record is easy is a thing of the past. These are, at times, very complex. The documentation is oftentimes unclear of the significance of the findings. Just because it is documented in the newborn record does not mean it should be coded. There are specific guidelines for this chapter of coding that must be followed.
Reasons for DRG 793/794 recommendations:
The majority of the recommendations from DRG 793 (Full term neonate with major problems) and DRG 794 (Neonate with other significant problems) were due to addition, deletion, or revision of CC/MCC (only 6 out of 137 required physician query).
- The most common reason for changes was for addition, deletion, or specificity of CC/MCC. There were several records that the CC/MCC was not clearly documented or supported. Almost all of these had the supporting documentation at the time of original coding for the CC/MCC.
- The remainder of the reasons for DRG recommendations was to re-sequence or add a new PDX. Only a couple of these required a physician query for clarification.
What can coders do to improve the accuracy of reporting DRG 793/794?
The most important thing that a coder can do is to make sure that there are no questions that could be raised regarding any diagnosis or procedure that is used to calculate the DRG. Ask yourself these questions when coding:
- Validate all CC/MCC’s to ensure that documentation is in the medical record to support that these conditions should be reported. If there’s a chance that the condition may be ruled out, a query should be sent for clarification. When only 1 MCC is present on a record it is always best practice to double check to ensure that the condition meets reporting requirements as well as clinical validity so that it is protected in any audits.
- Birth process vs. community acquired conditions should be clearly documented. If the condition is community acquired, Chapter 16 codes would not be used to report the condition. If the etiology is not clear, a query would be necessary.
- Follow the coding guidelines for additional secondary diagnosis with one addition. If the physician has documented that a condition has implications for future health care needs codes would be assigned. Even if the condition is not treated per se on this admission, if there is documentation that in the future this condition will require treatment it would be reported.
- Prematurity is only reported when documented by the physician.
- Query anytime there is ambiguous of conflicted documentation prior to coding finalization
- Bottom line is to protect the DRG at final coding by making sure that it is correct, and that there will be no question after final billing about the ICD-10-CM and/or ICD-10-PCS codes that were reported.
Coders should review the entire medical record to look for any conflicting documentation and clarify this prior to final coding. Clarification prior to final coding will decrease audit recommendations and denials. Remember, denials are costly to the facility with all the time that is spent trying to appeal.

ICD-10-PCS Official Guidelines for Coding and Reporting FY 2022
The information contained in this coding advice is valid at the time of posting. Viewers are encouraged to research subsequent official guidance in the areas associated with the topic as they can change rapidly.
Wow, have you seen the proposed rule for FY2023 IPPS yet? There are 1,495 proposed coding changes to ICD-10-CM diagnoses codes alone! There are also some IPPS changes to note. As for ICD-10-PCS, there are not as many new codes, most significantly occlusion of prostate artery and knee joint replacement codes.
Coding denials are sent after the auditor has reviewed the record in question and the auditor does not agree with the DRG that was paid. This can be for either a diagnosis or a procedure code that they think does not meet reporting requirements.
Introducing HIA’s Cloud-Based Audit Software, Atom Audit, Streamlining Your Coding Auditor’s Workday and Transforming Data into Action
Our new coding audit platform is an easy-to-use and intuitive coding review application, with a customizable reporting dashboard, that enables auditors to efficiently and effectively manage the entire audit lifecycle.
As of April 1, 2022 discharges, the following changes in ICD-10 and IPPS will be implemented. For years the coding community did not see changes occurring in April of the fiscal year. HIM professionals were used to not even worrying about April changes. This year, we do have some significant code additions and a change in the IPPS CC/MCC edit. The ICD10MCE and Grouper Version will be 39.1.
DRG 640 (Miscellaneous disorders of nutrition, metabolism, fluids, and electrolytes with MCC) was the number 9 most common DRG with recommendations from HIA in 2021.
DRG 981 (Extensive O.R Procedures unrelated to principal diagnosis with MCC) was the number 8 most common DRG with recommendations from HIA in 2021.
DRG 291 (Heart failure with shock with MCC). This should be no surprise to coders that DRG 291 is in the top DRG’s with recommendation. It seems to always be in the top 5 and a focus for denials.
DRG 177 (Respiratory infections and inflammations with MCC) and 178 (Respiratory infections and inflammations with CC). This should be no surprise to coders that DRG 177 is in the top DRG’s with recommendation.
Sepsis is and will most likely always be a troubled area for coders. There are multiple reasons for this and we will look at a few of these. There are many different criteria being used to validate the diagnosis of sepsis.
During a recent review of spinal fusion cases at a client, we found coding issues on the cases in which both an anterior interbody fusion, anterior open approach was done on one day and two days later, the patient was brought back for a posterior fusion, posterior open approach. Below are some of the recommendations we made along with education explanations.
This is Part 5 of a five part series on the new 2022 CPT codes. For the remaining areas we will just briefly summarize the section. Due to the intricate nature of these sections in CPT, it is recommended that the coder read the entire section notes associated with the new codes.
This is Part 4 of a 5 part series on the new 2022 CPT codes. In this one we will explore the nervous, ocular and auditory systems CPT changes.
This is Part 3 of a 5 part series on the new 2022 CPT codes. In this one we will explore the digestive, urinary and reproductive system CPT changes.
This is Part 1 of a five part series on the new 2022 CPT codes. In this series we include examples to help the coder understand the new codes.
10 ICD-10 Codes from the Christmas movie Home Alone. T20. 10XA for Harry, Burn of first degree of head, face, and neck, unspecified site, initial encounter. T20.56XA for Kevin and his aftershave incident, Corrosion of first degree of forehead and cheek, initial encounter.
Clinical trials are research studies performed in people that are aimed at evaluating a medical, surgical, or behavioral intervention. They are the primary way that researchers find out if a new treatment, like a new drug or diet or medical device (for example, a pacemaker) is safe and effective in people.
In Part 4 of the series, we will review the NTAP procedure codes and reimbursement add-on payments. Prepare yourself as this is rather lengthy due to continuation of NTAP that would normally expire.
Coders are instructed, at this time, to follow the AHA Frequently Asked Questions Regarding ICD-10-CM/PCS Coding for COVID-19. Lately, we have seen missing PCS codes for the new technology drugs that were introduced on August 1, 2020 and thereafter.
With the creation and implementation of ICD-10-CM, multiple codes are available to describe the type of pulmonary emboli that occur.
