R10.21
ICD-10-CMThis code signifies discomfort or aching localized to the right side of the pelvic region and/or the perineum. It indicates a symptom rather than a definitive diagnosis, pointing to pain experienced in the lower abdominal area, groin, or the region between the anus and external genitalia on the right.
Utilize this code when documentation specifies right-sided pelvic or perineal pain without a more specific underlying diagnosis. This is appropriate for initial encounters where the etiology is unknown or when the pain itself is the primary reason for the visit. Documentation should clearly state the location of the pain as "right pelvic" or "right perineal."
