Key Concepts in ICD-10-CM

• ICD-10-CM stands for the International Classification of Diseases 10th Revision, Clinical Modification.
• New ICD-10-CM updates occur annually in October.
• When both acute and chronic conditions exist, such as in coding guidelines, always sequence the acute condition first.
• Eponym Example: Paget's Disease, named after Sir James Paget.
• Default Code: The code next to a main term in the ICD-10-CM Alphabetic Index signifies the most common associated condition.
• Combination Code Example: K80.00 recognizes conditions like gallbladder calculus and acute cholecystitis.
• Sequencing Codes: For conditions with various symptoms, the relevant codes are sequenced correctly based on clinical guidelines.
• NEC (Not Elsewhere Classifiable) designates conditions lacking a specific code but categorized under a general heading.

Reporting Guidelines

• Report both the condition and the symptoms until a definitive diagnosis is established.

• Always reference and verify codes in the Tabular List as coding accuracy is pivotal.

• Report the main condition for procedures, even if subsequently canceled due to contraindications.

• Treatment Examples: For ailments like muscle weaknesses or infections, appropriate codes are assigned based on clinical findings and history.### Diagnosis Codes Summary
