2025 ICD-10-CM code S00.94

External constriction of unspecified part of head.

Use secondary codes from Chapter 20 (External causes of morbidity) to indicate the cause of the injury. Use additional code Z18.- to identify any retained foreign body, if applicable.

The code requires a 7th character extension to indicate the encounter type (initial encounter: S00.94XA, subsequent encounter: S00.94XD, sequela: S00.94XS).

Medical necessity for using this code is established by the presence of signs and symptoms of external constriction of the head. The documentation should clearly demonstrate the need for medical intervention due to the constriction.

Providers diagnose the condition based on patient history and physical examination. Treatment may involve removing the constricting object (if still present) and pain relief medication like analgesics or NSAIDs.

In simple words: External constriction of the head happens when something tight, like a band or belt, presses on the head, reducing blood flow. This code is used when the exact location on the head isn't specified by the doctor.

External constriction refers to external tightening of a body part by an outside force, such as a band, belt, or heavy object, which may lead to temporary constriction or restriction of blood flow. This code applies to external constriction of a part of the head not documented by the provider and not represented by another code.

Example 1: A child gets a rubber band wrapped tightly around their head during play, causing temporary constriction and a headache. The exact location of the constriction isn't specified., An adult experiences head pain after wearing a tight headband for an extended period. The headband caused external constriction, and the specific area of the head affected is not documented., A patient presents with head discomfort after a heavy object briefly pressed against their head. There is no open wound, and the physician does not specify the precise location of the constriction.

Documentation should include the cause of the constriction (if known), the duration of the constriction, symptoms experienced (e.g., pain, headache, tingling, numbness), and any associated injuries. Additionally, the treatment provided should be documented (e.g., removal of the constricting object, pain medication). Documenting the patient's response to treatment is also important.
