ICD-10 Ch 2 C codes

ICD-10 Neoplasms - tumors - cancer

QuestionAnswer
First step in coding a neoplasm. Read record to determine if neoplasm is benign, in-situ, malignant, or uncertain histologic behavior.
How should the coder code primary malignant neoplasms which are overlapping? Classify to subcategory .8 (overlapping lesions), UNLESS the combination is indexed elsewhere.
How should the coder code if there are multiple neoplasms that are NOT contiguous? A separate code should be used for each of the tumor locations.
How are malignant tumors of ectopic tissue coded? Code to the site of origin mentioned in the medical record.
If the histologic term for a neoplasm is documented, what should be referenced first? The Alphabetic Index or the Neoplasm Table? Why? The Alphabetic Index. To determine which column of the Table is appropriate.
Is it necessary to go to the Tabular after referencing the Neoplasm Table? Yes
What is the principal diagnosis when the treatment is directed at the malignancy? the malignancy UNLESS if sole reason for admission/encounter is chemo/rad tx/immunotherapy.
If sole reason for admission/encounter is chemo/rad tx/immunotherapy. what should be coded first? Z51.-- is first followed by malignancy dx.
If encounter is solely to treat a secondary site of malignancy while the primary malignancy is still present, what is considered the principal dx/first coded? The secondary neoplasm.
Are there any coding guidelines specifically for complications of malignancies and/or their treatment? Yes, Anemia due to malignancy, due to chemo/immun tx/rad tx, dehydration, complication from surgical procedure all have their own guidelines in Chapter 2.
If there is no longer any evidence of the primary tumor, what code should be used? Personal History of malignant tumor Z85.
If the primary tumor gone, but a secondary site has been discovered invastion, extension, or metastisis, what should be coded? The secondary site first-listed as a secondary tumor followed by Personal Hx of previous primary tumor/site.
Where should the coder look for coding guidelines regarding complications of chemo/tad tx/immun tx? In Chapter 2 guidelines. First-listed/principal code is the malignancy; followed by codes for complications.
If both surgery and chemo/rad tx are performed in the same encounter/admission, what should be coded first? the neoplasm code is first.
Under what circumstances would the code for "Disseminated malignant neoplasm, unspecified" be used? ONLY when widespread metastasis with no specified primary or secondary site
Under what circumstances would the code for "Malignant (primary) neoplasm, unspecified" be used? When no determination can be made as to the primary site of the malignancy.
What code equates to "Cancer, unspecified"? "Malignant (primary) neoplasm, unspecified" . Code C80.1
Where can a coder look to determine appropriate sequencing of neoplasm codes? Chapter 2 guidelines, L 1) - 6)
If a malignancy occurs in a transplanted organ, what is the correct first code? code for a transplant complication is first; then code for Malignant neoplasm assoc with transplanted organ.
Steps for coding a neoplasm 1. ID histology/morphology; 2. Refer Neoplasm Table; 3. Find correct column in Neoplasm Table; 4. Reference Tabular List.
Sequencing of diagnosis codes depends on type of tumor treatment is directed toward. True or False? True. If tx is directed at primary tumor, primary tumor is first-coded. If tx is directed at secondary tumor, secondary tumor is first-listed.
If encounter is for only chemo/rad/immun tx, then which code is the first-listed code? the first-listed code is a Z51- code
If the encounter is to treat a complication associated with a neoplasm, what is the correct sequence for coding the malignancy and its complication? The complication is first listed; Then the malignancy is next. Exception: Anemia assoc with malignancy.0.0
How many codes are needed when an encounter is to treat a side effect of tx for the malignancy? Three. 1. code for the complication; 2. Adverse Effect code; 3. Neoplasm code.
