CCDS IBHRE STUDY GUIDE OBJECTIVE
2026 COMPREHENSIVE QUESTIONS WITH
PRECISE ANSWERS GRADED A+
⩥ Official rules and codes are updated and approved by. Answer: 4
Governing Cooperating Parties: AHA, AHIMA, CMS, NCHS
⩥ Anatomy of PCS code structure (1-3). Answer: 1. Section or general
category of the procedure
2. Body system or region within the body that's the focus of the
procedure
3. Root operation or intent of procedure (e.g., extraction, excision,
release, etc.).
⩥ Anatomy of PCS code (4-6). Answer: 4. Body part
5. Approach (e.g., open, percutaneous, endoscopic, etc.)
6. Device implanted
7. Qualifier (unique meaning for each procedure that gives an extra
piece of information that completes the code, e.g., diagnostic biopsy).
⩥ Anatomy of CM code structure (1-3) (4-6) (7). Answer: 1-3: Category
4-6: Etiology, anatomical site, severity
,7: Extension (a code that has an applicable 7th character is considered
invalid without it)
⩥ Sequelae/complication coding timeframe. Answer: No time limit as to
when this type of code can be assigned.
⩥ PDX definition. Answer: 1. Determines the DRG and known as 'what
bought the bed'
2. UHDDS "the condition established after study to be chiefly
responsible for occasioning the admission"
3. Assigned even if the original plan of care is not carried out.
⩥ Threatened or impending coding. Answer: 1. If it occurred, code as
confirmed
2. Did not occur, check Alphabetic Index for subentry and main term
entry terms for "impending" or threatened".
- If listed, assign the code
- If not listed, code the existing underlying condition, but not the
condition described as "impending: or "threatened"
⩥ Laterality code assignment. Answer: If the condition is bilateral, but
there is no bilateral code, then assign separate codes for both R and L.
, ⩥ How would you code either/or diagnoses?. Answer: Code both as
confirmed diagnoses.
⩥ When can you code conditions that are otherwise considered integral
or inherent to another condition?. Answer: When it requires care beyond
usual treatment. (e.g., pleural effusion and CHF - treating with just
diuretics, you would not code the pleural effusion. Treating with
thoracentesis, you would code both, indicating a higher severity of
illness and level of resource consumption for CHF).
⩥ Chapter-specific guidelines (HIV) - when to report?. Answer: - Only
report confirmed cases of HIV code B20.
- This is an exception to the possible/probable rule.
- Does not need a positive blood test, but does need provider
documentation of HIV diagnosis with symptoms or HIV related illness.
⩥ Sequencing HIV as PDX or SDX. Answer: 1. B20 PDX when patient
is admitted to treat HIV or HIV related condition.
2. B20 SDX when admitted for an unrelated condition to HIV.
⩥ Organisms/infections that are exception to uncertain terms (need to be
confirmed). Answer: Zika
COVID-19
