Our experts answer questions on the new ICD-10-CM serotonin syndrome code, key takeaways for documenting and supporting malnutrition diagnoses, and appropriate circumstances for reporting codes from ICD-10-CM subcategory E66.8- (other obesity).
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?
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?

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.

Q: Based on the instructions for sacroiliac joint injections, our physicians believe they can bill the injection and report imaging separately if they use ultrasound. Is this true?
Q: Consider patients who are admitted with cellulitis and have type 2 diabetes mellitus with no neuropathy or elevated glucose levels. Should coders query the provider to clarify if the cellulitis is caused by the diabetes, or should such a query only be sent if a patient has other complications of diabetes such as hypoglycemia or neuropathy?
Q: How do I know when to use CPT code 26370 vs. 26356, for a finger tendon repair? Is it based on whether there is an intact flexor digitorum superficialis (FDS) tendon, or whether the cut or laceration of the flexor digitorum profundus (FDP) tendon was in Zone II?
