Genetic medicine is an emerging specialty coders will be faced with, and a basic foundation of the science and consequences of genetic anomalies will be helpful going forward. Realizing coders are not expected to be clinical, Nancy Reading, RN, BS, CPC, CPC-P, CPC-I , shows how it will still be useful to know the basics.
Q: A female patient previously had an inpatient stay due to severe enteritis secondary to the use of Keytruda for colon cancer that she was diagnosed with six months earlier. While she has had positive results to the medication, she presented to the ER last week due to severe abdominal bloating and cramping with diarrhea and stools with large amounts of mucous. She was dehydrated and hypokalemic upon inpatient admission and has a history of depression. Her discharge note indicates that her potassium levels and dehydration are normalized. How would this encounter be reported in ICD-10-CM?
Because multiple organ disfunction syndrome does not have a specific ICD-10-CM code, coders face the challenge of capturing the full complexity of the condition. Nevertheless, understanding the various organ systems involved and recognizing the specific dysfunctions can help coders accurately report the condition.

Q: A frail 74-year-old female presents with severe shortness of breath and hypoxia. She has a known history of smoking two or more packs per day for the past 40-50 years and has a complex history of chronic obstructive emphysema, centrilobular emphysema, bronchiectasis, and pulmonary hypertension. Her current hospitalization is due to MRSA pneumonia with planned discharge to home health for continued care. How would this diagnostic note be reported in ICD-10-CM?
Because substance use, abuse, and dependence are critical areas within healthcare that impact CDI and coding, Alba Kuqi, MD, MSHIM, RHIA, CCM, CRCR, CICA, CSMC, CSAF, CCS, CCDS, CDIP , provides readers with an in-depth analysis of these conditions and emphasizes their clinical, diagnostic, and coding implications.
Q: An elderly male patient has a rectal fistula with an abscess requiring complex packing of the wound. The most recent wound documentation reports “complex persistent rectal fistula with underlying abscess present, cultures show positive for E. coli and Klebsiella.” The patient will be administered daily IV antibiotics via a PICC line that has been placed. How would this encounter be reported in ICD-10-CM?
Acute respiratory distress syndrome presents a significant clinical challenge due to its rapid onset, high mortality rate, and complex management. Alba Kuqi, MD, MSHIM, RHIA, CCM, CRCR, CICA, CSMC, CSAF, CCS, CCDS, CDIP , delves into the comprehensive aspects of ARDS to show how coders, alongside healthcare providers and CDI specialists, play an essential role in reporting the complete picture of the condition.
Trey La Charité, MD, FACP, SFHM, CCS, CCDS , invites a deeper understanding for diagnosing and documenting acute renal failure and any other related diagnoses—before exploring the plethora of denial strategies medical staff may face. Not to worry as there are opportunities for successful appeals!
An upcoming audit reviewing Medicare inpatient hospital billing for sepsis underscores the critical importance of accurate coding and clinical validation. With guidance from Leigh Poland, RHIA, CCS, CDIP, CIC , coders can help prevent costly coding errors, reduce the risk of audits, and ensure hospitals are appropriately reimbursed for the care they provide.

Q: Patient presents with a chief complaint of persistent cough for 10 days with occasional mucus. She has a history of chronic asthmatic bronchitis for many years; is quite frail, reporting decline in energy and activity tolerance; was a smoker until about five years ago; and suffers chronic smokers’ cough and centrilobular emphysema. Past medical history includes heart failure, hypertension, and pulmonary hypertension. How would this diagnostic note be reported in ICD-10-CM?
To align subcategories for diagnosis coding with the DSM-5 classification subcategories for feeding and eating disorders, new ICD-10-CM codes were added in the FY 2025 update. Nancy Reading, RN, BS, CPC, CPC-P, CPC-I , reviews the clinical criteria for affected disorders, including anorexia nervosa, bulimia nervosa, binge-eating disorder, pica in adults, and rumination disorder.
Certain diagnosis-related groups (DRGs) remain vulnerable to audits and denials, not only for DRG and clinical validation, but for medical necessity as well. Kim Conner, BSN, CCDS, CCDS-O , explores areas coding professionals can support when being proactive against these denials.
Coding professionals face challenges when the clinical meanings of words do not match the ICD-10-CM classification system, particularly for records related to matters of the heart. Follow Laurie Prescott, RN, MSN, CCDS, CCDS-O, CDIP, CRC , as she applies critical thinking, knowledge of disease processes, and an understanding of ICD-10-CM codes to accurately report acute MI cases.
Q: A 65-year-old female has been on Effexor for major depressive disorder for three months and went to her healthcare provider due to tachycardia and palpitations along with mild muscle cramping. It was found that she had accidentally been taking double her prescribed dose due to misunderstanding the instructions. It is reported that she developed serotonin syndrome resulting from toxicity and was also diagnosed with mild hypertension (138/88) due to the serotonin syndrome. How would this encounter be reported in ICD-10-CM?
Coagulopathy describes the impairment of the blood’s ability to coagulate, leading to prolonged or excessive bleeding that may occur spontaneously or following an injury. Explore the basics of the condition as well as practical tips for accurate ICD-10 coding. Note : To access this free article, make sure you first register here if you do not have a paid subscription.
Lymphoma diagnosis codes received a robust overhaul with the release of the 2025 ICD-10-CM codes, reflecting advancements in understanding and classifying lymphoma. Accurate coding is crucial for reporting such nuances, and Nancy Reading, RN, BS, CPC, CPC-P, CPC-I , is here to update coders on the changes.
Q: A patient presents with exacerbation of COPD complicated by positive COVID-19 with COVID-19 pneumonia and superimposed MRSA bacterial pneumonia in the setting of chronic bronchitis due to smoking, severe persistent asthma (not currently in exacerbation), and left lower lobe lung cancer in remission following a lobectomy one year ago. Patient continues to smoke cigarettes. How would this diagnostic note be reported in ICD-10-CM?
With guidance from Linda Martien, CPC, COC, CPMA, CPC-I, CRC, AAPC approved instructor, AAPC fellow , coding professionals can review arthritis codes to avoid the use of generalized codes in order to reflect a patient’s condition more accurately and ensure compliance with insurance requirements.
Deanne Wilk, MPS, BSN, RN, CCDS, CCDS-O, CDIP, CCS, provides an overview of toxic encephalopathy including signs and symptoms, diagnosis and treatment, and relevance for coding professionals and CDI teams.
