ICD code S82.242E – Displaced spiral fracture of shaft of left tibia

Key takeaways

ICD-10 code S82.242E covers a displaced spiral fracture of the shaft of the left tibia at a subsequent encounter. The open type I or II fracture is healing routinely.

The seventh character E means routine healing, not malunion. Malunion of the same fracture at the same Gustilo grade is S82.242Q, and nonunion is S82.242M.

S82.242 accepts sixteen seventh characters. They cover initial encounters, sequela, and four healing outcomes across closed, type I or II, and type III fractures.

A routine healing follow-up pairs with office visit and imaging codes. Repair codes for nonunion or malunion, such as 27720 and 27722, do not belong on this claim.

The note must document laterality, spiral morphology, displacement, Gustilo grade, encounter sequence, and healing status before the code holds up.

What S82.242E covers, and why it is billable

S82.242E is a billable ICD-10-CM code, valid for diagnosis reporting in HIPAA-covered transactions. The official description reads:

Displaced spiral fracture of shaft of left tibia, subsequent encounter for open fracture type I or II with routine healing.

Per CMS ICD-10 coding guidance, a code that requires a seventh character is invalid on a claim without one. The base code S82.242 is not billable on its own.

The letter is what makes the code valid, so every character in it is worth reading on its own.

Every character in S82.242E carries one clinical fact

Reading the code from left to right lets a coder check pattern, side, and encounter type before the claim goes out. Here is what each position says.

Displacement and laterality share the sixth character, so one digit answers two questions. The fifth character carries the fracture pattern, and a spiral pattern comes from rotational force rather than a direct blow.

The CDC ICD-10-CM web tool lists each pattern under S82.2.

The 7th character packs three facts into one letter

The seventh character states the encounter sequence, the open fracture grade, and the healing outcome. S82.242 accepts sixteen of them, running A to S but skipping I, L, and O.

Three questions settle which one belongs on the claim.

E therefore sits at one precise intersection. The encounter is not the first. The fracture was open at Gustilo type I or II, and healing is on track.

Change any one of those three facts and the letter changes with it. A closed fracture healing routinely is D, and a type III fracture healing routinely is F.

The Gustilo grade is what separates E from D and F

The Gustilo-Anderson classification grades open fractures by wound size, contamination, and soft tissue damage.

Gustilo and Anderson described it in 1976, and the ICD-10-CM seventh characters group along the same lines.

Gustilo grading is a physician judgment made from intraoperative findings. The operative report has to state the grade, because a coder cannot assign type I or II from a wound description alone.

How the four healing outcomes move the letter

S82.242E is the routine healing code, so the other three outcomes sit under different letters. Which one applies is a physician determination recorded in the clinical or imaging note. A coder never infers it from the procedures billed.

Read across the row for the healing outcome, then down the column for the fracture grade. For an open type I or II fracture of the left tibial shaft, routine healing is S82.242E and malunion is S82.242Q.

The five visits that count as routine healing follow-ups

A subsequent encounter with routine healing is ordinary aftercare, not a complication visit. The patient has finished active treatment and returns so the surgeon can confirm the tibia is uniting as expected.

In practice, that is one of five visits.

• Post-operative or post-cast review with radiographs showing progressive callus
• Cast, boot, or brace change during the healing period
• Suture or pin site check on a type I or II wound that closed without infection
• Weight-bearing progression review after intramedullary nailing, with alignment maintained
• Rehabilitation review once physical therapy begins

Each of these is aftercare during the healing phase, which is what subsequent encounter means in ICD-10-CM. Active treatment of the injury itself takes an initial encounter character instead.

The sibling codes coders confuse with this one

S82.242E sits in a tight code family, and most miscodes on this diagnosis come from one of the codes below. Six of them change only the seventh character, so the difference is encounter grade or healing status.

One trap sits inside this list. The unspecified laterality code is S82.243E, not S82.249E. The sixth character in this subcategory runs 1 to 6, so it never ends in 9.

For the type III nonunion version of the same fracture, see ICD-10 code S82.242N. The AAPC ICD-10-CM lookup carries the full seventh-character list.

How the code narrows from a body region to one diagnosis

S82.242E is the last step in a chain that starts at a whole body region. Each level adds one fact, and only the seven-character version can go on a claim.

The phrases in a note that point to this code

Providers rarely write the code description word for word. These phrases in a follow-up note all point to S82.242E, provided the Gustilo grade and the healing status appear somewhere in the record.

• Healing open spiral fracture of the left tibial shaft
• Left tibia shaft fracture, Gustilo type I, healing as expected
• Follow-up for open left tibial diaphyseal fracture, callus forming
• Left tibial shaft spiral fracture, post-ORIF, alignment maintained
• Displaced spiral fracture of the left tibia, subsequent visit, wound healed

Synonyms help a coder recognize the diagnosis in free text. They do not replace the documented Gustilo grade, laterality, displacement, and healing status.

CPT codes that belong on a routine healing visit

A routine healing follow-up is an evaluation and imaging encounter, so the procedure list is short. The codes below fit the aftercare that S82.242E describes.

Payer bundling and global period rules still apply, so check coverage policy before submission.

Three codes get attached to this diagnosis by mistake. CPT 27720 and 27722 describe repair of nonunion or malunion of the tibia. Either one contradicts a routine healing seventh character.

CPT 27758 covers open treatment of a tibial shaft fracture, which is active treatment. That belongs with an initial encounter character such as B.

Six facts the note must show before you bill S82.242E

Six facts must appear in the record before this code is defensible. Missing any one of them produces a physician query, a less specific code, or a denial.

• Laterality: the note must state left tibia. Unspecified documentation forces S82.243E and invites medical review.
• Fracture morphology: the operative or radiology report must describe a spiral fracture. Mechanism of injury alone is not enough.
• Displacement: displaced must be documented. A nondisplaced spiral fracture of the same bone moves the code to S82.245E.
• Open wound with Gustilo grade: the operative report must state type I or type II. That grade is what separates E from D and F.
• Encounter sequence: the note must show active treatment has ended and this visit is aftercare.
• Healing status: the note must show routine, expected progress. Callus on imaging, maintained alignment, or a healed wound all support E, while any complication moves the code to another letter.

The ICD-10-CM Official Guidelines are explicit that aftercare Z codes do not apply to injuries. Follow-up care for a fracture uses the injury code with a subsequent encounter seventh character.

That is exactly what S82.242E does. Build these six checks into the follow-up template and the code stops depending on anyone’s memory.

Five coding errors that get this claim denied

These are the error patterns that generate denials and audit flags on this code. Each one starts in documentation rather than in the billing office.

• Reading E as malunion: this is the most common misreading of the letter. E means routine healing. Malunion at the same Gustilo grade is S82.242Q, and malunion of a closed fracture is S82.242P.
• Using an initial encounter character at a follow-up visit: A, B, and C apply only during active treatment. Once aftercare begins, the encounter is subsequent. Using B on a cast check is one of the most common fracture coding errors.
• Assigning E without a documented Gustilo grade: E requires type I or II in the operative report. Without that grade, a coder cannot tell E from F, and a closed fracture would need D instead.
• Billing nonunion or malunion repair against E: CPT 27720 and 27722 repair a failed or malaligned union. Pairing either with a routine healing diagnosis is a clinical inconsistency that payers flag.
• Coding unspecified laterality when the side is documented: payer edits increasingly reject S82.243E when the record names the side. Use S82.242E for the left tibia and S82.241E for the right.

How the claim moves, from follow-up visit to payment

Picking the letter is only the first step. Take a patient who returns six weeks after fixation of an open type II spiral fracture of the left tibia. Here is the path that claim takes.

1. The surgeon reviews the radiographs, records callus formation and maintained alignment, then closes the note.
2. A coder reads the note, confirms the six documented facts, and assigns S82.242E with the visit code.
3. The charge posts to the encounter, and the claim goes out on a CMS-1500 form or an 837P file.
4. The clearinghouse scrubs the claim against payer edits, then forwards it for adjudication.
5. The payer pays, or returns an electronic remittance advice naming the reason it did not.

Two of those steps fail more often than the rest. Step two breaks when the note never states the Gustilo grade, which leaves E and F indistinguishable. Step five breaks when the procedure contradicts the diagnosis.

The remittance then comes back carrying one of the standard denial codes instead of a payment.

A quick check before you submit

The documentation list above covers the note. This one covers the claim itself, and it takes about a minute.

• The seventh character on the claim matches the healing language in the note.
• The diagnosis and the procedures tell the same story, so no repair code sits under E.
• Laterality on the claim matches the laterality in the record.
• A visit inside the surgical global period goes out as 99024 rather than an office visit code.
• The date of service falls after active treatment ended, not during it.

Run that check once and most denials on this code never happen. Running it on every follow-up, for every patient, is the harder part.

How Pabau supports fracture coding and claim submission

Follow-up coding usually breaks down in the handoff between the exam room and the biller. The surgeon records that the tibia is uniting. Days later a coder rebuilds the seventh character from a note written for a clinical reader, not for a claim.

Practice management software like Pabau keeps the diagnosis, the charge, and the note on one patient record. Built-in ICD-10 and CPT catalogs let staff select S82.242E at the point of charge entry.

The seventh character then comes from a list instead of memory. Follow-up templates carry the six facts the code needs, which keeps the query rate down.

Our claims software for practices then files the claim, tracks its status, and posts the remittance against the same visit. When a denial does come back, it lands on the encounter that caused it. The fix therefore reaches the person who writes the note.

Conclusion

ICD-10 code S82.242E is a routine healing code, and that single fact shapes the rest of the claim. The encounter is aftercare, the original fracture was open at Gustilo type I or II, and the bone is uniting on schedule. The letter describes no complication at all.

Read the seventh character wrong and the claim tells a clinical story the note cannot support. Malunion and nonunion have their own letters for that reason. Keep laterality, morphology, displacement, Gustilo grade, encounter sequence, and healing status in the follow-up template, and the code assigns itself.
