Learn how infectious agents from bacteria or viruses determine diseases coded in other chapters, using examples like E. coli and Streptococcus, and how to handle unspecified causes.

Document antibiotic resistance for each patient and apply Z16 coding guidelines, selecting appropriate antibiotics and following general and client-specific guidelines for resistant infections.

Learn MRSA coding rules for sepsis and pneumonia, emphasizing cause-and-effect documentation, choosing codes accordingly, and handling non-combination codes when sequencing MRSA with sepsis or pneumonia.

Learn how methicillin-susceptible staphylococcus aureus and MRSA colonization require a separate ICD-10-CM code starting with Z22.23, and how to document colonization in charts.

Confirm Zika virus infection only when the condition is confirmed, and avoid coding if it is suspected; follow guidelines and query the physician to verify before coding.

Explore the neoplasm chapter, including benign, malignant, metastatic, and secondary cancers, and learn how overlapping sites and the alphabetical index and tabular list guide primary versus secondary coding.

Learn how to code treatments directed at malignancy or cancer, prioritizing cancer as the first listed diagnosis and handling encounters for chemotherapy or radiation therapy.

Learn how to code secondary cancer sites in ICD-10-CM, using examples of lung cancer metastasizing to bone, and distinctions between primary, secondary, and specified codes, including principal vs secondary diagnosis.

Learn coding and sequencing for complications, focusing on anemia due to malignancy or chemotherapy or radiation therapy, and dehydration due to malignancy, with guidelines on the proper order of diagnoses.

Explain how to code a primary malignancy that was excised, using the patient’s personal history of cancer to determine classification by organ or body site.

code the primary cancer during admission to establish the malignancy extent, not the treatment. note that follow-up care may involve chemotherapy or radiation, while paracentesis and thoracentesis support assessment.

Determine when to code signs and symptoms with neoplasms versus the cancer itself, and when a symptom is not integral, code both the symptom and the cancer.

Prioritize admission coding for pain control management by coding pain due to neoplasms first, then cancer, in accordance with ICD-10-CM guidelines.

When coding malignancy in two or more non-contiguous sites, capture all documented cancers and ensure the code description reflects each condition; query the physician if documentation is unclear.

Learn to code malignant neoplasms with unspecified site, including when to use unspecified primary cancer codes and how documentation cues guide coding of secondary cancer.

Identify whether a patient has current malignancy or a history of malignancy to guide ICD-10-CM coding, distinguishing active treatment from history when no further evaluation is needed.

Explain aftercare and follow-up, including prophylactic organ removal, with coding guidance for cancer and transplanted organ scenarios and key z codes to document follow-ups and complications.

Explore endocrine and metabolic diseases with a focus on diabetes guidelines, when to use diabetes conditions versus endocrine conditions, and the role of insulin and the pancreas in diabetes.

Explore diabetes mellitus types, including type one (juvenile) and type two, and how physician documentation guides ICD-10-CM coding decisions.

Code diabetes with or without insulin based on documentation, and add long-term insulin use only if documented. Do not assume insulin or short-term recovery when coding.

Explore pain disorder related to psychological conditions and master coding rules: use core codes 40–45 for exclusive psychological documentation, or add a D89 code for acute or chronic pain.

Learn how to code mental and behavioral disorders due to substance use using ICD-10-CM, applying the hierarchy remission, use, abuse, and dependence based on documentation.

Identify MSBP by proxy by evaluating self or other, adult or child, and physiological or physical disorders. Confirm or suspect status, and determine initial or subsequent coding implications.

Discover three pain coding guidelines for ICD-10-CM: when to list underlying conditions first, when to code pain in conjunction with unrelated neck conditions, and when admission is for pain control.

Assess post-operative pain for its association with complications, then assign ICD-10-CM codes accordingly; use non-complication codes if not associated, or complication-related codes with documentation guidance.
