      • Fracture of skull and facial bones (S02)

S02.631B is a billable diagnosis code used to specify a medical diagnosis of fracture of coronoid process of right mandible, initial encounter for open fracture. The code S02.631B is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code S02.631B might also be used to specify conditions or terms like closed fracture of coronoid process of right mandible, closed fracture of mandible, coronoid process, closed fracture of ramus of right mandible, closed fracture of right mandible or fracture of coronoid process of mandible.

S02.631B is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like fracture of coronoid process of right mandible for open fracture. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.

Coding Guidelines

The principles of multiple coding of injuries should be followed in coding fractures. Fractures of specified sites are coded individually by site nd the level of detail furnished by medical record content.

A fracture not indicated as open or closed should be coded to closed. A fracture not indicated whether displaced or not displaced should be coded to displaced.

Initial vs. Subsequent Encounter for Fractures

Traumatic fractures are coded using the appropriate 7th character for initial encounter (A, B, C) for each encounter where the patient is receiving active treatment for the fracture. The appropriate 7th character for initial encounter should also be assigned for a patient who delayed seeking treatment for the fracture or nonunion.

Fractures are coded using the appropriate 7th character for subsequent care for encounters after the patient has completed active treatment of the fracture and is receiving routine care for the fracture during the healing or recovery phase.

Care for complications of surgical treatment for fracture repairs during the healing or recovery phase should be coded with the appropriate complication codes.

Care of complications of fractures, such as malunion and nonunion, should be reported with the appropriate 7th character for subsequent care with nonunion (K, M, N,) or subsequent care with malunion (P, Q, R).

Malunion/nonunion: The appropriate 7th character for initial encounter should also be assigned for a patient who delayed seeking treatment for the fracture or nonunion.

The open fracture designations in the assignment of the 7th character for fractures of the forearm, femur and lower leg, including ankle are based on the Gustilo open fracture classification. When the Gustilo classification type is not specified for an open fracture, the 7th character for open fracture type I or II should be assigned (B, E, H, M, Q).

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code S02.631B its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Information for Patients


Fractures

A fracture is a break, usually in a bone. If the broken bone punctures the skin, it is called an open or compound fracture. Fractures commonly happen because of car accidents, falls, or sports injuries. Other causes are low bone density and osteoporosis, which cause weakening of the bones. Overuse can cause stress fractures, which are very small cracks in the bone.

Symptoms of a fracture are

You need to get medical care right away for any fracture. An x-ray can tell if your bone is broken. You may need to wear a cast or splint. Sometimes you need surgery to put in plates, pins or screws to keep the bone in place.

Jaw Injuries and Disorders

Your jaw is a set of bones that holds your teeth. It consists of two main parts. The upper part is the maxilla. It doesn't move. The moveable lower part is called the mandible. You move it when you talk or chew. The two halves of the mandible meet at your chin. The joint where the mandible meets your skull is the temporomandibular joint.

Jaw problems include

Treatment of jaw problems depends on the cause.
