NeoplasmsChapter II

HS317b - Coding & Classification of Health Information

  • Can occur in all body systems
  • Can be classified by anatomical site, behaviour and morphology.
  • To code neoplasms think in terms of the disease process
coding rules for neoplasms
Coding Rules for Neoplasms
  • MRDx is based on what site they are treating (primary or secondary)
  • Apply specificity standard
  • Assign separate codes for each primary and secondary
  • Morphology coding is optional
  • C80 Malignant neoplasm without specification if documentation is vague
primary neoplasm
Primary Neoplasm
  • Code to point of origin
    • This includes when cancer invades into adjacent tissue and is still connected to original site
    • Be as specific as documentation allows
  • Code to site
example ca of the small intestine
Example: Ca of the small intestine
  • C17 Malignant neoplasm of small intestine
    • Duodenum (C17.0)
    • Jejunum (C17.1)
    • Ileum (C17.2)
    • Meckel’s diverticulum (C17.3)
overlapping boundaries contiguous sites
Overlapping Boundaries (contiguous sites)
  • Within a 3-digit category & point of origin is underdetermined
  • Example:
    • C17.8 Overlapping malignant lesion of small intestine
overlapping sites within certain systems
Overlapping sites within certain systems
  • Overlaps the boundaries of three-character categories within certain systems. See note at beginning of neoplasm chapter
  • E.g. Ca of stomach (C16.~) and small intestine (C17.~)
    • C26.8 Overlapping lesion of digestive system
overlapping systems
Overlapping systems
  • C02.8 Overlapping lesion of tongue
  • C08.8 Overlapping lesion of major salivary glands
  • C14.8 Overlapping lesion of lip, oral cavity and pharynx
  • C21.8 Overlapping lesion of rectum, anus and anal canal
  • C24.8 Overlapping lesion of biliary tract,
  • C26.8 Overlapping lesion of digestive system
  • C39.8 Overlapping lesion of respiratory and intrathoracic organs
  • C41.8 Overlapping lesion of bone and articular cartilage
  • C49.8 Overlapping lesion of connective and soft tissue
  • C57.8 Overlapping lesion of female genital organs
  • C63.8 Overlapping lesion of male genital organs
  • C68.8 Overlapping lesion of urinary organs
  • C72.8 Overlapping lesion of central nervous system
metastatic neoplasms
Metastatic Neoplasms
  • When solid malignant neoplasms spread to other sites through local invasion of adjacent sites, metastasis to distant sites or seed.
  • ICD-10 does not make a distinction between method of metastasis.
  • This excludes local invasion into tissue within a body system (Code to point of origin).
  • Other terminology—secondary neoplasm
lymphomas and leukemia
Lymphomas and Leukemia
  • These neoplasms do not metastasize to secondary sites. They circulate within the lymphatic or hematopoetic circulation and may occur in other sites within these tissues.
  • Assigned to morphology rather than site.
admissions following diagnosis of ca
Admissions following diagnosis of CA
  • Patient admitted for definitive surgery to remove tissue from site of previous biopsy & pathology report is negative for malignancy.
    • MRDx is primary neoplasm
    • i.e.: Ca of breast. For diagnosing purposes a needle biopsy of lump shows CA. Patient admitted for lumpectomy & pathology was negative for malignancy
follow up admissions
Follow up admissions
  • Various scenarios can be encountered to allow one to code history or follow up codes
    • Recurrent malignancies
    • Interventions after diagnosis of Ca made
    • Observation for suspected malignancy
    • History of malignant neoplasms
    • Chemotherapy/Radiation
    • Prophylactic interventions
recurrent malignancies
Recurrent Malignancies
  • Example
    • Ca of right breast—lumpectomy removed entire lesion
    • A year later returns with lesion at site of previous lumpectomy. According to documentation this is a recurrence of the primary malignancy.
  • Ca previously eradicated but recurrent in the same organ or tissue
    • Code as primary (unless documentation directs you differently)
    • Include code for history of malignancy
    • C50.90 Ca R breast + Z85.3 Personal history of malignant neoplasm of breast
observation for suspected ca
Observation for suspected CA
  • When a patient presents with symptoms but tests prove negative for malignancy
    • Malignancy is ruled out
    • No further treatment is necessary


Z03.1 Observation for suspected malignant neoplasm

history of malignant neoplasms
History of Malignant Neoplasms
  • Different scenarios
    • Personal history of malignancy
    • Follow up examinations after initial intervention
    • Family history of malignancy
personal history z85
Personal History – Z85.~
  • Never to be used as MRDx
  • Always assign diagnosis type 3
  • Only assign for primary malignancies
    • When Ca has been completely eradicated/excised
    • No further treatment directed toward primary
    • No evidence of any remaining Ca at primary site
    • There is a recurrence at same site that was previously excised
follow up examination
Follow up Examination
  • When no disease is found
    • Through follow up investigation
    • No treatment indicated
  • MRDx: Z08.~ Follow-up examination after treatment for malignant neoplasm
  • Diagnosis type 3: Z85.~ Personal history of Ca
family history of ca
Family History of Ca
  • Z80.~ Family history of malignant neoplasm
  • Never used as MRDx
  • Assign diagnosis type 3
  • Denotes reason for prophylactic organ removal
prophylactic organ removal
Prophylactic Organ Removal
  • There is a family history of malignancy
    • Z80.~ Family history of malignant neoplasm
  • Tests like PSA (Prostate Specific Antigen) or CA 125 (Cancer Antigen) positive
  • No disease is present
  • MRDx: Z40.~~ Prophylactic organ removal
complications of malignancy
Complications of Malignancy

If complications are the cause of admission

  • Complication is MRDx
  • Malignancy is coded & assigned diagnosis type 3
  • Common complications
    • Bacterial sepsis
    • Chemotherapy induced neutropenia
    • Febrile neutropenia
    • Dehydration
    • Hypercalcemia
  • An abnormally low level of neutrophils in the blood.
  • Neutrophils are white blood cells produced in the bone marrow that ingest bacteria.
  • It is sometimes called agranulocytosis or granulocytopenia.
  • It is a serious disorder because it makes the body vulnerable to bacterial & fungal infections.
Neutropenia may result from three processes
    • Decreased WBC production
    • Destruction of WBCs
    • Sequestration and margination of WBCs
Recovery from acute neutropenia depends on the severity of the patient infection & the promptness of treatment.
  • When both neutropenia & fever are documented in the chart, code both D70.0 Neutropenia & R50.9 Fever, unspecified.
dagger asterisk standard
Dagger †/Asterisk * Standard
  • Dual Combination for circumstances when there are two codes for diagnostic statements containing information about both an underlying generalized disease and a manifestation in a particular organ or site which is a clinical problem in its own right.
    • † code marks the primary code for the underlying disease
    • * code marks the manifestation code.
dagger asterisk
Dagger †/Asterisk *
  • Dagger † may be MRDx, diagnosis type 1, 2 or 3.
  • Asterisk * is always diagnosis type 3 and may never be used alone.
    • “in”, “due to” or “with”
  • Anaemia in neoplastic disease
    • D63.0* Anaemia in neoplastic disease (C00-D48†)

Folio Lookup

Cancer - see also Neoplasm, malignant (8000/3)

8000 3 morphology classification
8000/3 = Morphology Classification
  • Describes the cell of origin (histological type)
  • Describes the behaviour of the neoplasm
  • Optional to use
  • Always Diagnosis type 4
  • When morphology diagnosis contains two qualifying adjectives, the higher # should be used
Five digits
    • First four # identify histological type of neoplasm
      • 8000 Neoplasm
      • 8140 Adenocarcinoma NOS
      • 8140 Adenocarcinoma, metastatic NOS
/Fifth # indicates behaviour
    • /0 Benign
    • /1 Uncertain whether benign or malignant
    • /2 Carcinoma in situ
    • /3 Malignant, primary site
    • /6 Malignant, metastatic site
    • /9 Malignant, uncertain whether primary or metastatic
review of coding neoplasms
Review of Coding Neoplasms
  • Code to point of origin
  • Has the malignancy been either excised or eradicated?
  • Is no further treatment being directed to the primary site?
  • Is there no further evidence of remaining malignancy at the primary site.
  • Account for primary with either malignant code or ‘history of’ code
  • Therapeutic
      • Destruction, excisional partial, excisional total, excisional radical or excision with reconstruction
  • Diagnostic
    • Inspections (endoscopy) biopsies
    • MRDx is Z51.1 Chemotherapy session for neoplasm
      • Neoplasms (active & historical malignancies) may be coded as diagnosis type 3
      • Intervention: 1.ZZ.35.~ ~ (identify specific drug) for systemic or total chemotherapy
    • MRDx is Z51.0 Radiotherapy session
    • Neoplasm (active & historical malignancies) may be coded as diagnosis type 3)
    • Intervention 1.~ ~. 27. ~ ~ Radiation therapy includes anatomical site & type of radiation.
    • MRDx is malignancy
    • Intervention is 1.QT. 26. ~ ~ (implant of radioactive material)
