ICD code S06.341D – Traumatic right cerebral hemorrhage follow-up

Key takeaways

S06.341D codes a follow-up visit for a traumatic bleed in the right cerebrum after a loss of consciousness of 30 minutes or less.

The 7th character D applies once active treatment is complete and the patient is receiving routine care while the injury heals.

Loss-of-consciousness duration comes from the acute-care record. LOC of 31 to 59 minutes moves the code to S06.342D, and 1 hour to 5 hours 59 minutes to S06.343D.

Laterality matters, because a left-sided bleed is S06.351D and an epidural bleed belongs to a separate category, S06.4X-.

Pabau, the practice software we build, connects to Claim.MD so neurology and neurosurgery practices can submit S06.341D claims and rework denials from one record.

ICD-10 Code S06.341D: Definition and quick-reference data

ICD-10 Code S06.341D is a valid, billable ICD-10-CM diagnosis code for a traumatic bleed in the right cerebrum at a follow-up visit.

Its official descriptor is Traumatic hemorrhage of right cerebrum with loss of consciousness of 30 minutes or less, subsequent encounter. It applies once active treatment has ended and the patient is in the healing or recovery phase.

Each character after the category narrows the meaning. S06 is intracranial injury, and the 4th character 3 places the code in S06.3, focal traumatic brain injury. The 5th character 4 identifies a hemorrhage in the right cerebrum.

The 6th character 1 records a loss of consciousness of 30 minutes or less. The 7th character D marks a subsequent encounter. The breakdown below also shows which neighbor code each character points to when the record disagrees.

The descriptors on this page match the FY2027 ICD-10-CM tabular, effective October 1, 2026. Confirm any code against the CDC/NCHS ICD-10-CM web tool, which updates each October for the new fiscal year.

Understanding the 7th character D: What subsequent encounter means

In ICD-10-CM Chapter 19, the 7th character tells the payer where the patient is in the episode of care. Three characters apply to S06.341:

Section I.C.19.a of the ICD-10-CM Official Guidelines ties the A character to active treatment. Whether the provider is seeing the patient for the first time does not matter.

A practice that first meets the patient after discharge still reports D if active treatment is over. A neurosurgeon who re-operates on a re-bleed reports A again, because treatment is active.

No fixed number of days or weeks moves a code from D to S. The switch is clinical and depends on what the visit treats. For a sequela, the late effect itself is sequenced first and S06.341S follows it, with the S added only to the injury code.

Loss-of-consciousness ladder for S06.340 to S06.349

The 6th character of every S06.34 code records loss of consciousness (LOC). S06.341 requires documented LOC of 30 minutes or less, which the tabular also calls brief loss of consciousness. The duration comes from the acute-care record and is carried forward unchanged to every follow-up visit.

If the emergency record documents 20 minutes of unconsciousness, S06.341D is correct at every follow-up. A 45-minute duration points to S06.342D, and 2 hours points to S06.343D. Category S06 notes that D and S never apply to 6th characters 7 or 8, because those codes record a death.

Two of the rungs are easy to mix up. S06.349 means the patient lost consciousness but nobody recorded how long. S06.34A means the record cannot say whether consciousness was lost at all.

S06.341D vs adjacent codes: How to choose correctly

Most S06.341D errors come from one character that does not match the record: the encounter, the duration, the side, or the type of bleed. The table compares the neighbors coders confuse most often.

Inclusion notes, exclusion notes, and code-also requirements

The ICD-10-CM tabular attaches notes to S06, S06.3, and S06.34. Each one applies to S06.341D and changes which other codes appear on the claim.

What S06.341D includes

Subcategory S06.34 includes traumatic intracerebral hemorrhage and hematoma of the right cerebrum. S06.341 adds traumatic hemorrhage of the right cerebrum with brief loss of consciousness. Category S06 as a whole includes traumatic brain injury.

What S06.341D excludes

Category S06 carries an Excludes1 note for head injury NOS, coded S09.90. S06.3 carries an Excludes2 note for conditions classifiable to S06.4 through S06.6, plus focal cerebral edema (S06.1). Excludes2 means those conditions are not part of S06.341D, but both codes may be reported when the patient has both.

A patient with a right cerebral bleed and a traumatic subdural hematoma therefore gets S06.341D and a code from S06.5X-. A bleed with no traumatic cause is coded to I61.-, nontraumatic intracerebral hemorrhage, instead of S06.34-.

Code also and use additional code notes

• Open wound of head (S01.-): code also any associated scalp or facial wound.
• Skull fracture (S02.-): code also any associated fracture, with the fracture 7th character for the visit.
• Traumatic brain compression or herniation (S06.A-): use an additional code if applicable, sequenced after the S06.3 code.
• Mild neurocognitive disorder (F06.7-): use an additional code if the physician documents one due to the injury.

External cause codes

There is no national requirement to report external cause codes. A state mandate or a payer policy can still require them, and the guidelines encourage reporting them voluntarily. When they are reported, the cause code takes the same encounter character as the injury code. Typical cause codes for this injury include:

• W00-W19: slipping, tripping, stumbling, and falls
• V00-V99: transport accidents, including motor vehicle collisions
• W20-W22: struck by a thrown, falling, or other object
• X92-Y09: assault

Place of occurrence (Y92) and activity (Y93) codes are generally reported once, at the initial encounter for treatment. They are usually left off an S06.341D claim.

Documentation requirements to support S06.341D

Auditors reviewing S06.341D claims look for proof of each character in the code. Missing any one of these elements raises the risk of a denial or a downcode.

• Traumatic cause: the record links the bleed to a specific event, such as a fall, collision, or assault. A spontaneous bleed points to I61.-.
• Site and side: CT or MRI findings place the hemorrhage in the right cerebrum. Note the study date and facility.
• LOC of 30 minutes or less: the duration appears in the emergency note, admission summary, or operative report. The follow-up note alone does not establish it.
• Glasgow Coma Scale scores: GCS scores from the acute event support both the diagnosis and the LOC bracket.
• Completed active treatment: the note shows the patient is past active treatment and receiving routine care while the injury heals.
• Link to the original injury: the note states the date of injury and that this visit manages that injury.

Practices using claims management software that connects to a clearinghouse can check these details before the claim goes out. That cuts rework on S06.341D denials.

Payer requirements and common S06.341D claim denial reasons

Pre-authorization rules for outpatient follow-up after a brain injury vary by plan, so check them with each payer. The denial patterns below recur across payer types.

Practices that send electronic claims through a clearinghouse such as Claim.MD can catch formatting and code errors before a claim reaches the payer. Denial management in healthcare works best when those errors are caught before submission, not at remittance review. The CMS ICD-10 codes page publishes the annual code files that drive payer edits.

Sequencing S06.341D alongside other diagnoses

In outpatient reporting, Section IV of the Official Guidelines uses the first-listed diagnosis in place of the inpatient principal diagnosis. When the visit is chiefly for the right cerebral bleed, S06.341D is listed first. Other conditions the physician addresses follow it.

Right cerebral hemorrhage with a skull fracture

Category S06 tells coders to code also any associated skull fracture from S02.-. Fracture codes use their own 7th characters, so a routine-healing follow-up for a vault fracture is S02.0XXD. Confirm the S02 code against the original imaging and operative reports.

A 6-week neurosurgery follow-up after a fall that caused a right cerebral bleed and a vault fracture could be coded as:

1. S06.341D (Traumatic hemorrhage of right cerebrum with loss of consciousness of 30 minutes or less, subsequent encounter)
2. S02.0XXD (Fracture of vault of skull, subsequent encounter for fracture with routine healing)
3. W19.XXXD (Unspecified fall, subsequent encounter), if external cause codes are reported

Other traumatic intracranial bleeds follow the same 7th-character logic in separate S06 categories. Epidural hemorrhage is S06.4X-, traumatic subdural hemorrhage is S06.5X-, and traumatic subarachnoid hemorrhage is S06.6X-. Code each bleed the record documents.

Comorbidities at the follow-up visit

Conditions unrelated to the injury, such as hypertension or diabetes, follow the injury codes and use their standard codes. The D character belongs only to the injury codes from Chapter 19 and any external cause codes. A clean claim on a multi-diagnosis visit depends on each code matching the visit.

Clinical context: What a subsequent encounter for right cerebral hemorrhage involves

Knowing the clinical pathway helps coders choose between D and S with confidence. A subsequent encounter for this injury usually includes one or more of the following:

• Neurology or neurosurgery follow-up: a review of recovery after discharge, often repeated while symptoms settle
• Repeat neuroimaging review: a head CT or brain MRI that tracks resorption of the bleed or flags new findings, such as hydrocephalus
• Cognitive and functional assessment: notes on memory, attention, headache frequency, mood, and left-sided motor or sensory changes
• Return-to-work or return-to-activity decisions: documented clearance supports medical necessity, especially for physically demanding jobs or athletes
• Medication management: changes to antiseizure, pain, or blood pressure medication, recorded in the note

When the note records these elements, the coder can confirm D and show medical necessity from the same document. Once the physician documents that recovery is complete, a visit for a late effect moves to S06.341S. The code for the late effect is then listed first.

How Pabau supports clean S06.341D claims

Coding S06.341D correctly depends on details spread across several records: the acute LOC duration, the imaging side, and the follow-up note. When those sit in separate systems, a coder rebuilds the picture by hand for each claim.

Pabau keeps treatment notes, forms, and invoices in the patient’s record. Through the Claim.MD integration, practices submit claims electronically and see payer responses, so a rejected encounter character can be corrected and resent quickly.

Manage ICD-10 claims without the denials

Pabau integrates with Claim.MD so neurology and neurosurgery practices can submit clean ICD-10 claims, track denial reasons, and resubmit corrected encounters faster.

Conclusion

S06.341D is correct only when four facts line up. The bleed is traumatic, it sits in the right cerebrum, LOC lasted 30 minutes or less, and active treatment is over. Check each one against the acute record and the imaging report, not the follow-up note alone. A single mismatched character turns a clean claim into a denial.

The coder who anchors the code to the original documentation rarely needs to defend it later. Pabau’s medical billing workflow, with the Claim.MD integration, gives neurology and neurosurgery practices one place to check those facts before submission.
