Insect bite (nonvenomous) of lower back and pelvis, sequela

This code signifies a long-term or late-effect condition resulting from a nonvenomous insect bite specifically affecting the lower back and/or pelvic region. This could include persistent scarring, chronic dermatitis, nerve damage, or other lasting complications directly attributable to the original bite. It indicates that the acute phase of the bite has passed, and the patient is now experiencing residual issues.

Use this code when documenting a patient presenting with a current condition that is a direct consequence of a nonvenomous insect bite to the lower back or pelvis that occurred in the past. This applies to follow-up visits for chronic issues stemming from such a bite, rather than the initial acute injury. Examples include treating keloid scars from a mosquito bite or chronic pruritus post-flea bite in the specified anatomical area.

• Always sequence this code after the code describing the specific sequela (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current condition to a past nonvenomous insect bite of the lower back or pelvis.
• Do not use for acute insect bites; those require codes from the T14-T19 range.
