ICD-10 code S60.152S: Contusion of left little finger with damage to nail, sequela

Key takeaways

S60.152S is a billable ICD-10-CM code for contusion of the left little finger with damage to nail, sequela

The S60.1 subcategory covers finger contusions WITH nail damage. Finger contusions without nail damage sit in S60.0 instead

In S60.152, the 5th character 5 means little finger and the 6th character 2 means left. The 7th character S makes it a sequela claim

A sequela claim needs a second code for the residual condition being treated, sequenced ahead of S60.152S

Pabau’s claims management software streamlines claim submission and helps reduce billing errors

ICD-10 code S60.152S describes a contusion of the left little finger with damage to the nail, reported at the sequela stage of care. It is a billable, specific ICD-10-CM code, and it is the code you reach for when the original bruise has resolved but a late effect of it has not.

Two details in this code get transposed more than any others. The nail damage element sits in the S60.1 subcategory, not S60.0, and the 7th character S is not interchangeable with A or D. Miss either one and the claim either denies or misstates the encounter in the patient record.

The code is accepted on both UB-04 (institutional) and CMS-1500 (professional) claim forms, so it works in hospital outpatient and physician office settings. ICD-10-CM is updated every October 1. Confirm the code’s active status against the CDC ICD-10-CM lookup tool for the fiscal year you are billing.

Billable status does not guarantee reimbursement. Coverage still turns on the individual plan and on medical necessity documentation.

What does S60.152S mean? Breaking down the code

Each segment of S60.152S carries a distinct clinical meaning. Reading the code position by position is the fastest way to confirm you have the right digit, the right side, and the right encounter stage before the claim goes out.

Read as a whole: the patient sustained a bruise to the left little finger that also damaged the nail, that injury has since healed, and today’s visit treats something the injury left behind.

The nail element is the trap. Contusion of a finger with damage to nail lives in S60.1. Contusion of a finger without damage to nail lives in S60.0. Same category, same digit and laterality logic, different fourth character, and payers treat them as different diagnoses.

Understanding the 7th character: initial vs. subsequent vs. sequela

The 7th character is the most frequently misapplied element in the S60 family. Per the CMS ICD-10-CM coding guidelines, the suffix reflects the status of the encounter rather than how the wound looks on the day.

Sequela is not a synonym for “still sore”. A patient who is mid-recovery and still under active management belongs on D, however long ago the injury happened. S applies once the contusion itself is done and a separate complication has taken its place.

Every injury code in Chapter 19 takes the same three suffixes, so the same test decides S60.159D and S59.009D. Learn the rule once and it travels across the whole chapter.

Billing teams handling HIPAA-covered transactions should build this distinction into coder training. A suffix error costs far less to prevent than to appeal.

Clinical description: contusion of the left little finger with nail damage

A contusion is a bruise caused by blunt force trauma without breaking the skin. In S60.152S the injury affects the fifth digit of the left hand, and the nail is involved. That usually means a subungual hematoma, a nail-bed injury, a partial nail avulsion, or pressure damage to the nail matrix.

Common mechanisms include crush injuries from doors, machinery, or dropped objects, plus sports impacts and workplace accidents. Clinicians in urgent care, occupational health, and sports medicine meet this pattern often, because the little finger sits on the outside edge of the hand and takes the impact first.

• Subungual hematoma: Blood pooling under the nail plate, sometimes drained by trephination
• Nail-bed injury: Damage to the tissue beneath the nail plate, monitored for later deformity
• Partial nail avulsion: Part of the nail plate lifted away from the nail bed
• Nail matrix pressure injury: Blunt trauma at the base of the nail that alters how the nail grows back

If the skin was broken, this is not the right family. An open wound of the little finger is coded from S61, and a crush injury from S67. Check the mechanism in the note before you commit to a contusion code.

What counts as a sequela of a little finger contusion

A sequela is a residual condition that persists after the acute injury has resolved. With a nail-damage contusion, the late effects usually show up in the nail itself or in the joint that took the impact. Typical presentations include:

• Nail dystrophy or permanent ridging after nail matrix damage
• Nail-bed scarring that leaves the regrown nail split or detached
• Chronic pain or hypersensitivity at the fingertip
• Reduced range of motion in the proximal or distal interphalangeal joint
• Post-traumatic stiffness that weakens grip on the ulnar side of the hand

Sequencing matters here. Per the ICD-10-CM Official Guidelines Section I.C.19, the code for the residual condition goes first and S60.152S follows it. So a claim for post-traumatic nail dystrophy would carry the nail disorder code, then S60.152S to explain where it came from.

S60.152S on its own is an incomplete story. It names a cause with no effect attached, and payers treat it that way.

Code hierarchy and parent codes for S60.152S

S60.152S sits inside a defined hierarchy under the S00-T88 injury block. Walking the levels confirms you have the most specific code available before you submit. The AAPC code lookup lays the same structure out visually.

S60.152 is not billable on its own. Only the 7th-character variants A, D, and S can go on a claim, and payers reject the bare parent code as non-specific.

Related and sibling codes

Three axes separate S60.152S from its neighbors: the encounter suffix, the laterality, and whether the nail was damaged. Confusing any one of them puts the wrong diagnosis on the claim, and the descriptions read so similarly that the error is easy to miss on review.

Two pairs deserve a second look every time. S60.151S versus S60.152S is the right and left decision, and S60.052S versus S60.152S is the nail decision. Take both from the clinical note, never from the previous claim.

If the provider also documents an open wound alongside the nail damage, a separate wound code such as S61.238A may be needed on the same claim.

Approximate synonyms and index terms

Coders who search by clinical wording rather than code number will meet these phrasings. Each maps to S60.152S or its parent S60.152. Recognizing them in a provider note speeds up lookup and lowers the chance of landing in the wrong subcategory.

• Late effect of bruised left little finger with nail damage
• Contusion of left pinky finger with nail injury, sequela
• Contusion of left fifth finger with damage to nail, sequela
• Residual nail deformity following left little finger contusion
• Old subungual hematoma, left little finger
• Left pinky blunt trauma with nail involvement, late effect
• Sequela of crush injury to left little fingernail

Documentation requirements for accurate coding

Denials on this code almost always trace back to a thin note. The record has to support five things, and a sequela claim adds one that the A and D variants do not need. Getting documentation practices right at the point of care prevents the rework later.

• Injury type: The note must describe blunt force or a crush without an open wound. If the skin was broken, code from S61 instead.
• Finger specificity: Little finger, fifth digit, and pinky all resolve to S60.15x. A note that says only “finger” pushes you to the unspecified code.
• Laterality: The record must name the left hand. Without it, S60.159S is the honest choice, and it invites payer questions.
• Nail involvement: Look for explicit mention of nail damage, subungual hematoma, nail-bed trauma, or nail avulsion. Without it, S60.0 applies rather than S60.1.
• Resolution plus a residual condition: The note should show the original contusion has healed and name what is being treated today. That second element also becomes the first-listed code.

A prior visit note, a discharge summary, or a referenced encounter date all work as evidence of the original injury. Practices that keep every visit for one injury in a single client record can pull that evidence in seconds instead of chasing it across systems.

Some practices attach a QuickDASH outcome measure to hand injury follow-ups. On a sequela visit the score gives the note concrete evidence that a functional deficit outlived the bruise.

Coding guidelines and compliance tips for S60.152S

These are the compliance issues coders hit most often in the S60.15x family. Official guidance is published each year in the ICD-10-CM Official Guidelines for Coding and Reporting, and ResDAC’s overview of ICD codes in Medicare files explains how the codes travel through claims data.

• Never report S60.152S alone: Sequence the residual condition first and S60.152S second. A single-code sequela claim is incomplete and often rejected outright.
• Do not default to A: The initial-encounter suffix belongs to active treatment of the acute injury. Once the contusion has resolved, A misstates the encounter.
• Check the nail element before the digit: S60.1 means nail damage was documented. If it was not, the claim belongs in S60.0, and S60.052S is the matching left little finger code.
• Verify laterality against the note: S60.151S is the right little finger and S60.152S is the left. Copying the side forward from a prior claim is how transposition errors spread.
• Billable does not mean covered: Medicare, Medicaid, and commercial payers set different medical necessity thresholds for late-effect visits.
• Recheck every October: ICD-10-CM is revised annually. Confirm S60.152S is still active in the fiscal year of service before you bill it.

Practices that run injury caseloads through physical therapy EMR software see the same episode move from A to D to S over months. Keeping that arc in one record is what makes the final sequela claim defensible.

How Pabau supports accurate coding on injury sequela claims

In most practices the injury history a sequela claim depends on is scattered. The original visit sits in one note, the follow-up in another, and the coder emails the provider to ask which finger and which side. The claim waits while that happens.

Practice management software like Pabau keeps the client record, the intake and follow-up forms, and the claim in one system. A follow-up template can ask for the injured side, the nail status, and whether the original injury has resolved, before the patient leaves the room.

Pabau’s claims management software then streamlines claim submission and helps reduce billing errors, and clinical record management keeps the full injury timeline in one place. Your billing team spends less time chasing detail and more time on claims that genuinely need a human.

Conclusion

S60.152S is narrow by design: the left little finger, nail damage documented, the bruise healed, and something it left behind still under treatment. Change any one of those facts and a different code applies.

The two errors worth guarding against are the nail element and the encounter suffix. S60.0 and S60.1 are not interchangeable, and neither are A, D, and S. Both are settled in the provider note, not at the billing desk.

Pair the code with the residual condition it explains, sequence the manifestation first, and the claim tells a complete story. Book a demo to see how Pabau keeps injury documentation and claim submission in one place.
