Q. Can you explain the difference between CPT codes 44140 and 44160? Both codes represent a partial colectomy, and I am unclear on what work must be performed after the colectomy to choose between the two codes.
A. These two codes often generate confusion for surgical coders. The confusion usually stems from uncertainty about what the term “ileocolostomy” which appears in the description of CPT 44160 means and what part of the bowel is removed in each procedure. Before we break down the definitions of both codes, if you are a visual learner and want a refresher on the anatomy of the colon, check out this image: Segments of the Colon Explained
For those of you coding laparoscopic colectomies, the same explanation provided above for CPT 44140 and 44160 also applies to CPT codes 44204 and 44205 in the laparoscopic world. CPT 44204 is for a laparoscopic approach with removal of part of the colon and a colocolonic anastomosis while CPT 44205 is for a laparoscopic approach with removal of part of the colon and the terminal ileum followed by an ileocolostomy.
Understanding the terminology in the code descriptions as well as the anatomy of the colon and the small intestine are keys to coding surgeries these surgeries accurately.
**Updated with new information as of 8/2/2020**
As our understanding of the COVID-19 virus continues to evolve from a clinical perspective, the coding guidance issued by the AHA continues to evolve as well. Changes to the previous guidance provided are in bold and captions with the text **Updated 8/2/2020** to help you spot the new guidelines and get the information you need quickly. AHIMA also has an updated article showing the latest AHA guidance with many different clinical scenarios addressed so I will link you to this great resource as well: https://journal.ahima.org/ahima-and-aha-faq-on-icd-10-cm-coding-for-covid-19/ .
While ICD-10-CM is not the usual focus of content we provide, the novel coronavirus (COVID-19) continues to impact healthcare professionals and facilities across the globe and is impacting daily life for many of us as well. With all the preparations going on and interruptions to daily life, one impact we may not have considered is the impact this new virus will have for us in our daily coding.
The CDC recently published interim guidelines for coding ICD-10-CM related to the treatment of patients who test positive for COVID-19 and for those who have had a known or suspected exposure and require further testing and workup. While the ICD-10-CM codes for COVID-19 might not be top of mind right now, ensuring that positive cases of COVID-19 and suspected exposure and testing are captured accurately from a coding perspective will ultimately help organizations who track and trend statistics in global health events understand the full impact of this new virus. So with that in mind, we want to dedicate today’s article to the proper coding of COVID-19 from an ICD-10-CM perspective, and provide a few case examples that might help those of you coding services for the treatment of patients impacted by the virus.
ICD-10-CM Codes for Novel Coronavirus (COVID-19):
Coding Tips for Novel Coronavirus (COVID-19):
Case Examples- Novel Coronavirus (COVID-19):
Example #1: A 56-year-old woman presents to the hospital with a three day history of dry cough, low-grade fever, and respiratory distress. The patient is admitted by the emergency department physician and ultimately tests positive for novel coronavirus . A pulmonologist is then consulted. After obtaining a chest x-ray, the pulmonologist diagnoses the patient with viral pneumonia related to COVID-19 and recommends a treatment plan to the physician who requested the consult. The visit is a level 4 consult. What is the coding for the pulmonologist?
Answer Example #1: CPT code is 99254 (for a level 4 inpatient consult for non-Medicare payers that accept consult codes or 99222 for Medicare or other payers that no longer allow consults). For a DOS on or prior to 3/31/2020, the ICD-10-CM codes for the pulmonologist will be J12.89 (other viral pneumonia) and B97.29 (other coronavirus as the cause of disease classified elsewhere). For a DOS on or after 4/1/2020, the ICD-10-CM codes for the pulmonologist will be U07.1 (COVID-19) and J12.89 (other viral pneumonia). While the patient presents with signs/symptoms, she now has a definitive diagnosis of novel cornavirus (i.e., COVID-19) and was diagnosed during the encounter as having viral pneumonia related to the COVID-19. Because the cause and effect between the viral pneumonia and the COVID-19 is documented, it is appropriate to code the viral pneumonia first followed by the code for COVID-19.
Example #2: A 70-year-old man has been admitted to the hospital for the past 5 days. The admitting physician has already diagnosed him with acute respiratory distress syndrome (ARDS) due to COVID-19, and his respiratory distress continues to worsen. The hospital intensivist performs emergent intubation to support his lungs. No other care other than the intubation is provided by the intensivist. What is the appropriate coding for this scenario?
Answer Example #2: CPT code 31500 would be reported for the emergent intubation. For a DOS on or prior to 3/31/2020, the ICD-10-CM codes for the intensivist will be J80 (acute respiratory distress syndrome) and B97.29 (other coronavirus as the cause of disease classified elsewhere). For a DOS on or after 4/1/2020, the ICD-10-CM codes for the intensivist will be U07.1 (COVID-19) and J80 (acute respiratory distress syndrome). Because the cause and effect between the ARDS and the COVID-19 is documented, it is appropriate to code the ARDS first followed by the code for COVID-19.
Example #3: A 25-year-old male who recently traveled to China with his family presents with a 2 day history of dry cough and a fever of 100.5 degrees Fahrenheit. His father was recently diagnosed with COVID-19 and was also traveling with him. The emergency room physician provides a level 4 ER visit including ordering a chest x-ray to rule out more severe respiratory disease and ordering a test for COVID-19 given the patient’s travel history and proximity to a family member who is positive for the virus. Test results will take another 1-2 days to return. What is the appropriate coding for the ER physician’s work?
Answer Example #3: CPT code is 99284 (for a level 4 emergency room visit). The ICD-10-CM codes for the ER physician will be R05 (cough), R50.9 (fever, unspecified), and Z20.828 (Contact with and (suspected) exposure to other viral communicable diseases).While the patient could certainly have COVID-19 given his recent travel to China and the fact that a close family member already has the disease, his test results are still pending at this time. Remember to only code B97.29 or U07.1 if the diagnosis of COVID-19 is definitive. For now, we should code the signs/symptoms he presented with (the cough and the fever) and his known contact with/exposure to COVID-19 through contact with his dad. **Updated 8/2/2020: The most recent AHA guidance suggests holding the claim for the test results to come back to ensure accurate coding of COVID-related diagnoses. Work with your employer/healthcare institution on the best coding protocols for your patients and specialty.**

If you are coding a tracheostomy procedure (CPT codes 31600-31610), you might be reading your operative report and suddenly see the physician mention the thyroid. This can be confusing at first, and this mention of a completely different organ that feels unrelated to the tracheostomy procedure may leave you feeling like you need to add an additional code for the work performed on the thyroid. However, this work is typically just part of gaining access to the trachea.
To explain, the thyroid isthmus (the cartilage that is in the middle of the thyroid gland and connects the two lobes) is located above the trachea, typically in the vicinity of the 3rd and 4th rings. To access the trachea and perform the tracheostomy, surgeons can sometimes retract the thyroid tissue (move it out of the way) without any incision into the trachea. However, when this is not possible, another common approach is to “divide” or “transect” the thyroid isthmus and then move the thyroid out of the way to gain access to the trachea. When a physician divides/transects the trachea, there is no disease or abnormality in the thyroid itself, and no part of the thyroid is actually being removed. The physician is simply dividing the thyroid and moving it out of the way to proceed with the planned procedure on the trachea. In this scenario, the division/transection of the thyroid is part of the approach to the tracheostomy which makes it bundle to the tracheostomy procedure.
To confirm the work on the thyroid is bundled, it is always helpful to look at guidelines from authoritative sources such as CMS and the AMA. In the National Correct Coding Initiative (NCCI) Policy Manual, which is published by CMS and provides guidance about procedures that bundle together, there are some helpful guidelines found in Chapter 1, section B: Coding Based on Standards of Medical/Surgical Practice: “Some procedures are integral in a large number of procedures…examples of procedures that are integral to a large number of procedures include…. Surgical approach including identification of anatomical landmarks, incision, evaluation of the surgical field, debridement of traumatized tissue, lysis of adhesions, and isolation of structures limiting access to the surgical field such as bone, blood vessels, nerve, and muscles including stimulation for identification or monitoring.”
In this example with the thyroid and the trachea, the thyroid must be isolated (or moved out of the way) because it is limiting access to the surgical field (the trachea). Therefore, the work on the thyroid falls under this guideline and is bundled to the tracheostomy since it is part of the surgical approach. Notice that it is how the two procedures relate to each other that make the division/transaction of the thyroid bundled.
