Comorbid conditions or complications (CC) and major comorbid conditions or complications (MCC) indicate a higher level of severity of illness, an elevated risk of mortality, and an above average intensity of resource utilization. Given their impact on reimbursement and quality reporting, Nancy Reading, BS, CPC, CPC-P, CPC-I, emphasizes how success in coding CCs and MCCs requires a delicate balance of documentation specificity and clinical clarity in diagnosis assignment.
Human immunodeficiency virus is a chronic viral infection with clinical manifestations that can range from an asymptomatic infection to AIDS, the most advanced stage of the disease. Because HIV-related diagnoses carry unique ICD-10-CM coding guidelines, coders must carefully review the medical record to determine whether the documentation supports assignment of HIV disease, asymptomatic HIV infection, or other HIV status, as well as the presence of any HIV-related illnesses.
Diagnosing opportunistic infections can be particularly challenging because the presenting signs and symptoms are nonspecific and may resemble a wide range of other conditions, making it difficult for providers to immediately identify the exact infectious process. Nevertheless, coders should recognize how clear documentation of both the infection and the underlying pathogen is particularly critical for proper code selection as many ICD-10-CM codes are organism-specific and dependent on the anatomical site or body system involved.

From a coding perspective, accurate reporting of artificial openings is essential because it communicates critical information about a patient’s anatomy, clinical status, and the level of care required. Coders must distinguish between a stable, well-functioning artificial opening (status), active management or attention to the opening, and true complications, as each circumstance is classified differently within ICD-10-CM.

Compared to recent past years, CMS proposed fewer ICD-10-CM code changes in the 2027 Hospital Inpatient Prospective Payment System proposed rule, including 184 new codes, 4 revised code descriptions, and 30 invalidated codes.
Q: How do coders determine whether to assign an ICD-10-CM P code (for maternal conditions affecting the newborn) or a Z code (for factors influencing health status) for a newborn?
ICD-11 elevates SDOH and other contextual factors into a more standardized, digital-first framework that can support the next generation of equity measurement, population health analytics, and financing models. Learn how ICD-11 SDOH coding is not just a classification change–it is an enabler of strategic goals in population health, financial sustainability, and equitable care delivery.
Hospitals have had a more complex time attempting to retain fair DRG payment by defending both the documented clinical diagnoses established by the treating provider and the corresponding codes in written appeal. Julie Dagen, RHIA, CCDS, CCS, seeks to address some key aspects of compliant hospital navigation through the rough waters of DRG denials.
Assigning and sequencing diagnosis codes for COPD in the face of an acute exacerbation of COPD, particularly when the patient’s condition progresses to respiratory failure, has posed challenges to coders for quite a while. Nancy Reading, BS, CPC, CPC-P, CPC-I, demonstrates how to nail down the diagnosis codes based on clinical presentations before determining the correct sequencing for principal diagnosis assignment.
Coding for alcohol- and drug-related disorders requires careful attention to both clinical terminology and the structure of the ICD-10-CM classification system. These conditions fall under the broader category of mental and behavioral disorders due to psychoactive substance use, primarily coded within the F10-F19 range.

Q: A patient with dementia has not taken prescribed Lasix for one week due to forgetting and presents with worsening acute heart failure. What is going to be sequenced first: the underdose or the acute heart failure?
Accurate reporting of left-sided heart failure types relies on specific ICD-10-CM codes that align with the documented ejection fraction category, although ICD-10-CM also provides specific codes for other clinically important forms of heart failure, with and without other chronic conditions, that reflect distinct pathophysiologic mechanisms and coding considerations.

At the recent public ICD-10 Coordination and Maintenance Committee Meeting, the Centers for Disease Control and Prevention National Center for Health Statistics discussed a draft proposal involving an expansion of sepsis diagnosis coding. Review the updates being considered for implementation on April 1, 2027. Note : To access this free article, make sure you first register if you do not have a paid subscription.
A report published by the American Cancer Society found that colorectal cancer rates among adults younger than 65 continue to increase while rates for older adults continue to decline. The study found that the increase is being driven by a higher prevalence of rectal cancer, which now makes up 32% of all colorectal cancer diagnoses, up from 27% in the mid-2000s.
Porcelain aorta is a disease that is caused by severe and widespread hardening of the walls of the ascending aorta that reaches to the aortic arch and descending aorta. Although there are several methods used to diagnose porcelain aorta, Brandi Hutcheson, RN, MSN, CCM, CCDS, CCA, says there is not a clear consensus on how it should be diagnosed.
In December 2023, the Office of the Inspector General published a toolkit for Medicare Advantage organizations who submit high-risk diagnoses, and it announced in January 2026 that an audit will be conducted on high-risk codes that the organizations submitted for 2024. Nancy Reading, BS, CPC, CPC-P, CPC-I, reviews the high-risk codes and emphasizes what to look for in the documentation to support coding practices.
According to data from the Centers for Disease Control and Prevention, the U.S. recorded 649 maternal deaths in 2024. While the total number of deaths declined slightly from 669 deaths in 2023, the overall maternal mortality rate showed no statistically significant improvement, highlighting ongoing challenges in maternal health outcomes.
Q: What steps should medical coders take to correctly code adverse drug effects in ICD-10-CM, and when should a provider query be submitted if documentation is unclear or unspecific?
