The primary ICD-9 codes used for Calcium Pyrophosphate Deposition Disease (CPPD), also commonly known as pseudogout, include codes for chondrocalcinosis and specific disorders of calcium metabolism.
Calcium Pyrophosphate Deposition Disease (CPPD) is a form of arthritis caused by the deposition of calcium pyrophosphate crystals in the joints. For medical billing and diagnostic classification under the ICD-9 system, specific codes are assigned to capture the various manifestations of this condition.
ICD-9 Codes for CPPD
The following ICD-9 codes are relevant for diagnosing and billing CPPD, encompassing various forms of chondrocalcinosis and broader calcium metabolism issues:| ICD-9 Code Range | Description |
|---|---|
| 712.1–712.39 | Chondrocalcinosis (due to dicalcium phosphate crystals, due to pyrophosphate crystals, or cause unspecified) |
| 275.49 | Other disorders of calcium metabolism |
These codes are crucial for healthcare providers to accurately document and process claims related to CPPD. The range 712.1–712.39 specifically covers the presence of calcium crystal deposits in cartilage, which is a hallmark of CPPD, differentiating between specific crystal types and unspecified causes. Code 275.49 provides a broader category for other metabolic disturbances involving calcium that might be associated with or contribute to the condition.
Understanding these codes helps in:
- Accurate Diagnosis: Ensuring that the patient's medical record reflects the correct diagnosis.
- Billing and Reimbursement: Facilitating proper billing for services rendered in relation to CPPD.
- Epidemiological Studies: Allowing researchers to identify and study patient populations affected by CPPD.
For more detailed information on specific medical codes, healthcare professionals often refer to comprehensive ICD-9 manuals or official coding resources. As healthcare systems transition, it's important to note that many countries have moved from ICD-9 to ICD-10 or newer versions for medical coding, which may use different code structures for similar conditions.
