Refresher: What are ICD-10 codes?

After WHO implemented the International Classification of Diseases, ICD-10 was enacted to supplement the allocation of death sentences and expedite the process of mortality coding in the United States. Today, ICD-10 codes have become an integral aspect of classifying injuries, diseases and all cancer types. Healthcare providers can use these codes to classify secondary tumors or secondary malignant neoplasms. [¹]

Healthcare providers, from nurses and medical coders to surgeons and physicians, significantly depend on ICD-10 codes to enhance patient treatment, diagnosis and outcomes. These codes are used for several other purposes. For example, medical practitioners pass them down to insurance providers who use them for billing.

Currently, there are approximately 68,000 ICD-10 codes, each possessing unique definitions. Many patients may encounter these codes on their medical bills, which can be confusing. However, fully comprehending them can be incredibly helpful in getting coverage and approvals for medical support.

When dealing with medical paperwork and billing, patients may also notice the ICD-10-CM. Although it can be described as the clinical adaptation of ICD-10, there is no distinction between the two since they are identical sets of diagnostic codes that healthcare providers use in the US.

The version of ICD 10 in the US comprises two sets of codes: ICD-10-PCS and ICD-10-CM. ICD-10-PCS differs from ICD-10-CM since it can be described as a procedural classification system for medical codes. This code is widely utilized in hospitals to report inpatient procedures. In simple words, while the ICD-10-PCS code is used for inpatient coding, the ICD-10-CM code defines patient diagnoses and demonstrates that the services provided were medically necessary. This article takes a look at the ICD codes for bone cancer. [²]

What is the ICD-10 code for bone cancer?

The bone cancer ICD 10 Code depends significantly on the location and type of bone cancer. According to the WHO, the ICD-10 code for malignant neoplasm of bone and articular cartilage of limbs is C40. Further classifications are described below. [³]

Primary bone cancer ICD 10 code: C40

Primary bone cancer ICD code C40 lookup

Below is a table of the ICD 10 bone cancer codes for primary bone cancers, classified under C40 "Malignant neoplasm of bone and articular cartilage of limbs."

C40: Malignant neoplasm of the bone

Types of bone cancer coded under C40

The ICD 10 code C40 does not specify the subtype of bone cancer. A C40 code can be used for primary bone cancers of various cell types:

• Malignant neoplasm of mandible (Cancer of the bones of the face or skull)
• Malignant neoplasm of short bones of lower limb (Cancer occurring in the short bones within the lower limb region)
• Malignant neoplasm of long bones of lower limb (Cancer occurring in the long bones within the lower limb)
• Malignant neoplasm of bone and articular cartilage, unspecified (Issued to patients whose primary cancer site has not yet been determined. It corresponds to cancers of the bone that develop in various bones or cartilages across the body)
• Malignant neoplasm of overlapping sites of bone and articular cartilage of limbs (Issued to patients with bone cancer that has spread to several bones in one or several limbs, but the precise location has not been determined)

Bone cancers excluded from ICD-10 C40

The ICD-10 coding system does not specify all types of primary bone cancers under the C40 category. Certain types of bone cancers have their specific code, including [⁴] [⁵]:

• Giant Cell Granuloma (M27.1)
• Multiple Myeloma (C90. 0)

Secondary and metastatic bone cancer ICD 10 code: C79.5

Secondary or metastatic bone cancer ICD-10 code C79.5 lookup

According to WHO, the ICD-10 code for secondary and metastatic bone cancer, listed under "Malignant Neoplasms," is C79.5. Secondary and metastatic bone cancers are further divided into different categories based on the site of the malignancy. C79.5 is the code used to refer to secondary malignant neoplasm of the bone and bone marrow. This code describes secondary bone cancer, originating from different sites and spreading to the bone or bone marrow.

It is worth noting that the specific ICD-10 code for secondary or metastatic bone cancer can be different. The site of cancer and several other factors help medical practitioners dictate which ICD-10 code applies to a specific case. A medical health professional may look at additional codes under the ICD10 C79 category or other relevant categories to determine the main location of cancer. To maintain high accuracy during coding, healthcare providers consider factors like histology, primary location, and other factors available on patient medical documents [⁶].

Conclusion

The ICD-10 coding system offers a systematic framework for categorizing bone cancers. These codes offer several benefits, allowing medical health providers to efficiently identify, monitor, and treat bone cancers. Healthcare professionals can ensure accurate coding and improve patient awareness, management, and results by referring to the ICD-10 codes for each bone cancer.
