Outpatient Coding Guidelines Flashcards

Which ICD-10-CM guideline applies to outpatient coding of HIV-related conditions?

Answer: Code B20 as first-listed when the encounter is for an HIV-related condition

When an HIV-positive patient is seen for an HIV-related illness, B20 (HIV disease) is sequenced first, followed by the specific HIV-related condition.

An outpatient is seen for pain management after a recent fracture. The fracture has not fully healed. How should this be coded?

Answer: Code the fracture with the appropriate 7th character for subsequent encounter

Subsequent encounters for fracture care use the 7th character 'D' (routine healing), 'G' (delayed healing), or other appropriate subsequent-care characters — not 'A'.

When a patient presents with signs and symptoms that are integral to a confirmed diagnosis, how are they coded?

Answer: They are NOT coded separately — they are included in the disease code

Signs and symptoms that are routinely associated with a confirmed disease process are not coded separately, as they are integral components of the diagnosis.

In outpatient coding, how should a patient encounter for screening colonoscopy where a polyp is found and removed be coded?

Answer: Code the screening Z-code first, then the polyp finding

When a screening procedure reveals a finding, first-list the screening Z-code (e.g., Z12.11), then add the code for the finding (e.g., polyp of colon).

A patient is seen in outpatient surgery for a knee replacement. The procedure is cancelled due to the patient developing acute respiratory distress preoperatively. What is the correct first-listed diagnosis?

Answer: The reason the procedure was cancelled (acute respiratory distress)

When a procedure is cancelled after the patient is prepared, the reason for cancellation (the complication or new condition) becomes the first-listed diagnosis.

How are 'Z codes' used in outpatient coding?

Answer: To describe encounters for reasons other than illness or injury (health status, screening, etc.)

Z codes classify encounters for circumstances other than a disease or injury, including preventive care, screenings, follow-up visits, and personal health history.
