The 2022 edition of ICD-10-CM L03.90 became effective on October 1, 2021.
Cellulitis. Cellulitis of skin with lymphangitis. Clinical Information. A bacterial infection that affects and spreads in the skin and soft tissues. Signs and symptoms include pain, tenderness and reddening in the affected area, fever, chills, and lymphadenopathy. An acute, diffuse, and suppurative inflammation of loose connective tissue, ...
cellulitis can be serious, and possibly even deadly, so prompt treatment is important. The goal of treatment is to control infection and prevent related problems. Treatment usually includes antibiotics. Inflammation that may involve the skin and or subcutaneous tissues, and or muscle.
Post-procedural Sepsis and Sepsis Due to a Device, Implant, or Graft. A systemic infection can occur as a complication of a procedure or due to a device, implant, or graft. This includes systemic infections due to wound infection, infusions, transfusions, therapeutic injections, implanted devices, and transplants.
For instance, if severe sepsis, pneumonia, and acute renal failure due to dehydration are documented, the code for severe sepsis may not be assigned because the acute renal failure is not stated as due to or associated with sepsis. If the documentation is unclear, query the physician.
You must query the physician when the term “sepsis syndrome” is documented as a final diagnosis. Know when to Query. Sepsis is a complicated condition to code, and it is often necessary to query the physician to code the case correctly.
Documentation issues: Often, a patient with a localized infection may exhibi t tachycardia, leukocytosis, tachypnea, and fever, but not truly have SIRS or sepsis. These are typical symptoms of any infection. It’s up to the physician’s clinical judgment to decide whether the patient has sepsis or SIRS.
Documentation issues: You can code for sepsis when the physician documents the term “sepsis.”. Documentation should be consistent throughout the chart. Occasionally, during an extended length of stay, sepsis may resolve quickly and the discharging doctor may not include the diagnosis of sepsis on the discharge summary.
term “sepsis” must also be documented to code a systemic infection. This is a major change from ICD-9-CM. If the term “sepsis” is not documented with “SIRS” when it’s due to a localized infection, you must ask for clarification from the physician.
Documentation issues: The term “septic shock” is occasionally documented without the term “sepsis.”. According to the guidelines, for all cases of septic shock the code for the underlying systemic infection is sequenced first, followed by R65.21 Severe sepsis with septic shock or T81.12- Postprocedural septic shock.
coli urinary tract infection (UTI). In this case, since the sepsis was present on admission and due to E. coli UTI, then A41.5- (Sepsis due to Escherichia coli) is the PDX followed by the diagnosis of UTI (N39.0-Urinary tract infection, site not specified) as a SDX code. Note, in this case no additional code was added for the E. coli bacteria causing the UTI, even though there is an instructional note, since the bacteria is clearly reported in code A41.51. Since the bacteria is responsible for both conditions, reporting the additional code for the bacteria would be redundant.
When sepsis is present on admission and due to a localized infection (not a device or post procedural), the sepsis code is sequenced first followed by the code for the localized infection.
Patients with devices, implants or grafts often develop sepsis due to the presence of the device. The link MUST be made by the physician. If this link is not made, or there is conflicting documentation, a query is necessary to clarify the cause and effect relationship.
As discussed in Part 1 of this series, sepsis is a common diagnosis for coders, however is oftentimes difficult to know how to sequence the diagnosis in ICD-10-CM. In Part 2, we are going to focus on sequencing of sepsis when the diagnosis is clearly documented. Later in the series we will look at what to do when the diagnosis is not clearly documented.
In this case, since the sepsis was not present on admission the localized infection of pneumonia (J18.9-Pneumonia, unspecified organism) is sequenced as the PDX followed by the diagnosis of sepsis (A41.9-Sepsis unspecified organism) as a SDX code.
When reviewing sepsis claims, all too often the primary focus is on searching provider documentation for signs and symptoms and/or clinical indicators that support the diagnosis of sepsis, or that support a query regarding the presence of sepsis.
Many times the more subtle details in the sepsis guidelines are overlooked, and sometimes they are not noticed at all. I would like to challenge readers to periodically review and re-review the guidelines in an effort to gain complete understanding of all aspects of sepsis coding, and consider the following sepsis coding scenarios.
However, it is important to note here that the absence of positive blood cultures in a patient with severe sepsis does not equal noninfectious sepsis.
Is sepsis always sequenced as the principal diagnosis when it is present on admission? Some may say yes , because after all, that’s what is stated in the official coding guidelines. However, my answer to this question is no, not always. I believe that there are very few absolutes in coding, and the sepsis guidelines are a good example of this. ICD-10-CM Official Coding Guidelines for Coding and Reporting direct us that “if severe sepsis is present on admission and meets the definition of principal diagnosis, the underlying systemic infection should be assigned as principal diagnosis followed by the appropriate code from subcategory R65.2 as required by the sequencing rules in the Tabular List.” We are further directed that, “if the reason for admission is both sepsis or severe sepsis and a localized infection, such as pneumonia or cellulitis, a code (s) for the underlying systemic infection should be assigned as principal diagnosis followed by the appropriate code from subcategory R65.2 as required by the sequencing rules in the Tabular List.”
We are directed by ICD-10-CM Official Guidelines for Coding and Reporting that even though negative or inconclusive blood cultures do not negate a diagnosis of sepsis in patients with clinical evidence of the condition; providers should be queried under these circumstances. So in this scenario, which is an actual real-life scenario, the provider would need to be queried as to the cause of patient’s septic shock and whether it was a noninfectious source (possibly patient’s GI bleed) or a suspected infection before an appropriate principal diagnosis could be chosen.
Sepsis can be caused by fungi, candida, or viruses, as well. It is important to use the Alphabetic Index to select the appropriate code for the systemic infection. For example, if a patient is diagnosed with candidal sepsis due to a candida UTI, you would report B37.7 Candidal sepsis for the principal diagnosis and B37.49 Other urogenital candidiasis for the secondary diagnosis. Do not select a code from A40.- through A41.9.
Coding tips: Only one code is needed to report sepsis without organ dysfunction. Most sepsis codes are listed in A40.- through A41.9. If a causal organism is specified, then use the code for sepsis naming the specific organism. Per AHA Coding Clinic® (Vol. 5, No. 1, p. 16), when sepsis is linked to an infection with an organism, assign the combination code for sepsis including the organism. For example, sepsis due to E. coli UTI can be coded as A41.51 and N39.0.
Sepsis is a potentially life-threatening condition that occurs when the body’s response to an infection damages its own tissues. Without timely treatment, sepsis can progress rapidly and lead to tissue damage, organ failure, and then death. Proper coding of sepsis and SIRS requires the coder to understand the stages of sepsis and common documentation issues.
Sepsis is an extreme response to infection that develops when the chemicals the immune system releases into the bloodstream to fight infection cause widespread inflammation. This inflammation can lead to blood clots and leaky blood vessels, and without timely treatment, may result in organ dysfunction and then death. Severe cases of sepsis often result from a body-wide infection that spreads through the bloodstream, but sepsis can also be triggered by an infection in the lungs, stomach, kidneys, or bladder. Thus, it is not necessary for blood cultures to be positive to code sepsis (guideline I.C.1.d.1.a.i).
For instance, if sepsis, pneumonia, and acute renal failure due to dehydration are documented, the code for severe sepsis may not be assigned because the acute renal failure is not stated as due to or associated with sepsis. If the documentation is unclear, query the physician.
Severe sepsis is sepsis with acute organ dysfunction. It occurs when one or more of the body’s organs is damaged from the inflammatory response. Any organ can be affected.
Documentation issues: When SIRS is documented with an inflammatory condition, such as pancreatitis, the inflammatory condition should be sequenced first, followed by the code for SIRS, R65.1-. When SIRS is documented with an infectious source, for instance, “SIRS due to pneumonia,” only code pneumonia. However, a query for sepsis may be appropriate according to AHA Coding Clinic® (Vol. 1, No. 3, p. 4).
