ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) and ICD-10-PCS (Procedural Coding System) codes serve different purposes in the medical field:
1. **ICD-10-CM codes** are used for diagnosing medical conditions and diseases. These alphanumeric codes describe the specific diagnoses a patient has received. For example, if a patient is diagnosed with pneumonia, the ICD-10-CM code for pneumonia would be assigned to that diagnosis.
2. **ICD-10-PCS codes**, on the other hand, are used for reporting procedures and services performed during inpatient hospital stays. These codes provide detailed information about the specific procedures conducted, such as surgeries, imaging tests, or other medical interventions. For instance, if a patient undergoes a knee replacement surgery, the ICD-10-PCS code for that specific procedure would be used.
In summary, while ICD-10-CM codes focus on diagnosing medical conditions, ICD-10-PCS codes concentrate on documenting procedures and services rendered during inpatient hospital stays. Both sets of codes are crucial for accurately recording and billing for healthcare services.
