question 12

a patient has a traumatic head injury, and some cerebrospinal fluid (csf) is removed to limit potential damage from swelling of the brain. the fluid is sent to pathology for examination and the results show unusual cytological counts, although no specific findings. the patient has had no other symptoms known to his family members. what is the icd-10-cm code for this examination of csf?

s06.1x0a
r83.6
z00.01
a39.0

Explanation:

Analyze the clinical scenario and diagnostic findings

The patient had cerebrospinal fluid (CSF) removed and sent to pathology for examination. The results show "unusual cytological counts, although no specific findings" (nonspecific abnormal findings). The patient has no other known symptoms.

Determine the correct ICD-10-CM code category

For nonspecific abnormal findings in cerebrospinal fluid (CSF) without a specific diagnosis, we look to the ICD-10-CM category R83 (Abnormal findings in cerebrospinal fluid). Specifically, abnormal cytological findings (unusual cytological counts) in CSF are coded as R83.6 (Abnormal immunological findings in cerebrospinal fluid / Abnormal cytological findings in cerebrospinal fluid).

Evaluate the given multiple-choice options

• S06.1X0A: Traumatic cerebral edema (not the code for the CSF examination findings).
• R83.6: Abnormal findings in cerebrospinal fluid, abnormal cytological findings (correct).
• Z00.01: Encounter for general adult medical examination with abnormal findings (incorrect).
• A39.0: Meningococcal meningitis (incorrect).

Answer:

• (A) S06.1X0A
• (B) R83.6 (Correct answer)
• (C) Z00.01
• (D) A39.0
