Neoplasm related pain (acute) (chronic)

This diagnosis code signifies pain directly attributable to a malignant neoplasm, whether the pain is acute or chronic in nature. It encompasses pain caused by the tumor's direct effects, such as compression, invasion, or obstruction, as well as pain resulting from cancer treatments. This code is used when the pain is a manifestation of the underlying cancer.

Apply this code when documentation clearly links the patient's pain to a diagnosed malignancy. This includes pain from primary tumors, metastatic disease, or complications arising directly from the cancer itself. Supporting documentation should specify the presence of cancer and the pain as a related symptom.

• Always sequence this code after the definitive diagnosis for the underlying malignancy.
• Do not use this code for post-procedural pain following cancer treatment unless the pain is explicitly documented as a direct, ongoing effect of the neoplasm itself.
• Ensure the medical record explicitly states "neoplasm related pain" or provides sufficient detail to establish the direct causal link between the cancer and the pain.
