ICD code S61.216S – Right little finger laceration without foreign body sequela

Key takeaways

S61.216S is a billable ICD-10-CM code for the sequela of a right little finger laceration without foreign body or nail damage.

The 7th character “S” means the wound has healed and the visit treats a late effect, such as a scar.

The late-effect code is sequenced first, with S61.216S listed after it.

Documentation must confirm the right side, the little finger, no foreign body, no nail damage, and a healed wound.

Common denials stem from the wrong 7th character, a mismatched digit or side, and a missing sequela code.

ICD-10 Code S61.216S: Code overview and clinical description

ICD-10 Code S61.216S describes a sequela visit after a laceration of the right little finger. The original cut had no foreign body in it and did not damage the nail. The code is valid for fiscal year 2027 claims, effective October 1, 2026, per the CMS ICD-10-CM code files.

Each part of the descriptor carries coding weight. “Laceration without foreign body” means a cut with no object left in the wound. “Right little finger” fixes both the side and the digit. “Without damage to nail” places the code in subcategory S61.2 rather than S61.3. “Sequela” marks the visit as late-effect care rather than active treatment.

Code classification and hierarchy

S61.216S sits within the ICD-10-CM injury chapter and inherits coding rules from every level above it. Knowing the hierarchy helps coders find adjacent codes and read Excludes notes correctly.

What the 7th character “S” (sequela) means

The 7th character “S” designates a sequela encounter, per ICD-10-CM Official Guidelines Section I.C.19.a. The provider treats a condition that arose as a direct result of a previous injury. The original wound has healed, but a late effect such as scarring, nerve sensitivity or reduced range of motion needs care.

Many coders confuse sequela with ongoing wound care. If the wound is still open or under active treatment, the correct character is “A” (initial encounter) or “D” (subsequent encounter). Applying “S” while the wound is still healing inverts the clinical scenario and invites a medical necessity denial.

ICD-10-CM guidelines require two codes when “S” is used: the injury code and a code for the sequela itself. The specific sequela, such as a scar, is sequenced first, followed by S61.216S. The “S” goes on the injury code only, never on the sequela code.

S61.216S vs S61.216A vs S61.216D: Choosing the encounter type

S61.216A covers active treatment, S61.216D covers routine healing visits, and S61.216S covers sequela care. Only one applies to any single visit. The base code S61.216 is identical across all three, and the 7th character decides whether the claim is defensible.

The quickest test is whether the wound is still open. If it is, use “A” or “D”. If the wound has healed and the patient returns for a complication of the original injury, use “S” alongside a code for that sequela.

Includes, excludes, and related codes

Excludes1, Excludes2 and “code also” notes at several levels govern which conditions can sit alongside S61.216S. They come from category S61, subcategory S61.2, block S60-S69 and the injury chapter.

Excludes1 notes (mutually exclusive)

Excludes1 notes mean the listed condition is never coded together with S61.216S. Category S61 excludes open fracture of wrist, hand and finger (S62.- with 7th character B) and traumatic amputation of wrist and hand (S68.-). Subcategory S61.2 also excludes open wound of finger involving the nail matrix, which is coded to S61.3-.

Excludes2 notes (may code additionally)

Excludes2 conditions are not part of S61.216S, but both may be coded when both are present. Subcategory S61.2 lists open wound of thumb without damage to nail (S61.0-).

Block S60-S69 lists burns and corrosions (T20-T32), frostbite (T33-T34) and venomous insect bites or stings (T63.4). The injury chapter lists birth trauma (P10-P15) and obstetric trauma (O70-O71).

“Code also” guidance

Category S61 carries a “code also” note for any associated wound infection. The injury chapter also calls for a secondary code from Chapter 20 to show the external cause of the injury. For post-laceration scar contracture of the right little finger, the scar code comes first and S61.216S follows it.

Adjacent codes that are easy to confuse with S61.216S

Codes near S61.216S differ by one character, and each character changes the clinical meaning. The 6th character sets the digit and side, the 5th sets the wound type, and the 4th sets nail involvement. The diagram maps each character and the neighboring code a single change produces.

S61.217S and S61.215S each sit one digit away from S61.216S in the code string. Confirm the side and finger in the visit note before finalizing the code.

Clinical documentation requirements for S61.216S

Every element of the S61.216S descriptor must be supported by the medical record. An audit that finds one missing element is grounds for denial or recoupment. Documentation that supports submitting a clean claim includes each of the following.

• Right laterality: The note must state “right little finger” or equivalent wording. “Right hand” is not enough, because the code needs digit-level detail.
• Digit identification: The little finger (fifth digit) must be named. A finger documented without a side moves the code to S61.218S.
• No foreign body: The original injury record should show that no foreign body was found in the wound. A documented foreign body moves the code to S61.226S.
• No nail damage: The record should show that the nail and nail matrix were not involved. Nail damage moves the code to subcategory S61.3, such as S61.316S.
• Sequela encounter type: The note must show that the original wound has healed and the visit treats a late effect. A phrase such as “scar management following healed right little finger laceration” supports the “S” character.
• Sequela condition code: A second ICD-10-CM code must name the specific late effect, such as a scar, contracture or nerve sensitivity. That code is sequenced before S61.216S.

Payer requirements and prior authorization notes

Medicare, Medicaid and commercial payers each apply their own medical necessity criteria to sequela claims. What follows reflects general payer patterns. Always check the current Local Coverage Determination (LCD) or payer policy for the date of service.

For Medicare claims, the ICD-10 code itself generally needs no standalone prior authorization. A procedure billed alongside S61.216S, such as scar revision or tenolysis, may need prior authorization under some Medicare Advantage plans. Fee-for-service Medicare does not typically require prior authorization for scar management office visits.

Commercial insurers vary widely. Some require proof of conservative management before they approve a scar revision. A claim pairing S61.216S with a high-complexity procedure and no conservative treatment history is a common audit trigger.

• CPT pairing: Check that the procedure code suits a sequela visit. Wound repair codes (CPT 12001-13160) usually fit initial or subsequent encounters, not sequela. Office visits (99202-99215), scar revision codes, or therapy codes are more likely to align with S61.216S.
• Medicaid: State Medicaid programs apply their own diagnosis-to-procedure edits. Some can reject S61.216S when it is paired with wound care procedure codes.
• Documentation timeline: Payers may request the original injury record to confirm the sequela link. Keeping the initial encounter on file, with the laceration details and laterality, prevents delays.

Common claim denial reasons for ICD-10 Code S61.216S

Claims coded with S61.216S are denied most often for five reasons. Each maps to a documentation or coding step that a structured review can catch before submission. Tracking them as part of denial management in healthcare lets a practice fix the cause before the same error reaches the next claim.

• Wrong 7th character: Using S61.216A or S61.216D for a sequela visit, or S61.216S for an active wound, is the most common error here. Payer edits compare the procedure code with the encounter type.
• Wrong digit or side: The diagnosis must match the right little finger named in the procedure note. If the note omits the side, the coder cannot select “6” and must use S61.218S, which some payers question.
• Excludes1 conflict: Listing S61.216S with a code from an Excludes1 note, such as traumatic amputation (S68.-), fails automated edits. Check every diagnosis on the claim against the S61 and S61.2 Excludes1 notes.
• Sequela not supported in the record: If the note describes an open wound or active wound care, the “S” character is not defensible. Post-payment reviews recoup claims where documentation contradicts the encounter type.
• Missing or misordered sequela code: Guidelines require a code for the specific late effect, listed before S61.216S. The denial codes on these rejections often cite incomplete diagnosis information or medical necessity.

How Pabau keeps S61.216S claims tied to the original injury

A sequela claim depends on notes from two visits, often months apart. If the original laceration note sits in a paper chart or another system, the biller has to chase it before the claim goes out.

Pabau, the practice management platform we build, links the S61.216S visit to the earlier injury visits in the same patient file. When a payer asks for the initial laceration record, your team can pull it in a few clicks.

Pabau’s built-in claims software for practices flags CPT-to-ICD-10 pairing issues before the claim leaves the practice. Claims then go out through the Claim.MD clearinghouse integration, which checks common payer edits before the payer sees them.

Reduce ICD-10 coding errors at the point of care

Pabau embeds diagnosis code search directly in the clinical workflow. Your team can attach the correct ICD-10-CM codes, document laterality and encounter type, and submit cleaner claims from one system.

Conclusion

S61.216S claims are won or lost on the 7th character. Before you pick “S”, check that the note describes a healed wound and names the late effect being treated. Then list that late-effect code first.

Once those checks hold, the remaining risk is a CPT code that doesn’t fit a sequela visit. Watch the electronic remittance advice on your first few claims. A repeat denial there usually points to one pairing rule worth fixing at the source.
