What scalp hematoma ICD-10 codes can I use?
A scalp hematoma is generally coded under contusion of scalp in the ICD-10-CM system, as there is no specific code solely for "scalp hematoma." The following codes are used based on the encounter type and progression of care:
S00.03XA - Contusion of scalp, initial encounter
S00.03XA - Contusion of scalp, initial encounter is meant to be used on a patient confirmed to have a scalp contusion. “Contusion” is the medical term for “bruise.” These result from damage caused to small blood vessels.
This code is used when a scalp hematoma is diagnosed during the first medical visit and the patient is receiving active treatment. It applies to direct trauma resulting in a bruise, swelling, or bleeding under the skin of the scalp.
S00.03XD - Contusion of scalp, subsequent encounter
This is the same as S00.03XA, but this time, there's a subsequent encounter label, which means the patient is in the recovery phase and is still being given active/routine treatment.
Use this code when the patient returns for follow-up care after the initial diagnosis. It indicates that the active phase of treatment has ended, and the provider is monitoring healing or managing ongoing symptoms.
S00.03XS - Contusion of scalp, sequela
This is the same as S00.03XA, but there's a sequela label this time, which means the patient is dealing with the aftereffects of the problem.
This code is applied when a complication or residual effect of a scalp hematoma is being treated (e.g., chronic pain, scarring, or tissue damage). It reflects a sequela, meaning the current visit addresses long-term effects of the original injury.
