Coding Cancer and Cancer-Related Treatments

One in three people in the U.S. will be diagnosed with cancer in their lifetime, according to the American Cancer Society. Accurately and completely coding and documenting cancer and cancer-related treatments may help improve member outcomes and continuity of care.

Below is coding-related information for outpatient and professional services from the ICD-10-CM Official Guidelines for Coding and Reporting.

Sample ICD-10-CM Codes for Neoplasms

Malignant neoplasms

C00-C96

In situ neoplasms D00-D09

Benign neoplasm

D10-D36

Benign endocrine tumors D3A

Neoplasm of uncertain behavior

D37-D48

Neoplasms of unspecified behavior D49

Personal history of malignant neoplasm

Z85.0-Z85.9

Coding Cancer and Cancer-Related Treatments

  • To properly code a neoplasm, specify if the neoplasm is benign, in situ, malignant or of uncertain histology. Any metastases should be noted.
  • All known treatments and complications should be documented.
  • A statement of “History of” indicates the condition is resolved. Don’t document “History of” for members with active cancer or current treatment. 
  • A code from Z85.x, Personal history of malignant neoplasm, is appropriate if a primary malignancy has been previously excised or eradicated from its primary site and there is no further treatment.

Tips to Consider

  • Include patient demographics such as name, date of birth and date of service in all progress notes.
  • Document legibly, clearly and concisely.
  • Ensure a credentialed provider signs and dates all documents.
  • Document how each diagnosis was monitored, evaluated, assessed and/or treated on the date of service.
  • Note complications with an appropriate treatment plan.
  • Take advantage of the Annual Health Assessment or other yearly preventive exam as an opportunity to capture conditions impacting member care.
  • Use ICD-10 Z codes for social determinants of health on the claims you submit to Blue Cross and Blue Shield of Illinois (BCBSIL) so we may better understand the unique, social needs of our members and help connect them with available resources.
