Fractures here typically result from axial load (a punch or fall onto a closed fist) or direct crush trauma.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A nondisplaced fracture at the base means the cortical surfaces have not shifted out of alignment on imaging. Open fractures at the metacarpal base are less common than closed injuries. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They carry a higher infection risk, because the wound communicates with the fracture site. Fractures of metacarpal bones 2 through 5 are relevant here; the 1st metacarpal (thumb) uses a separate code family (S62.2-).<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Common mechanism:<\/strong> direct impact or axial load to the dorsal hand<\/li>\n\n\n\n<li><strong>Imaging:<\/strong> plain radiographs in two or three views confirm nondisplacement and base location<\/li>\n\n\n\n<li><strong>Open vs. closed:<\/strong> the wound must communicate with the fracture site to qualify as open. A laceration elsewhere on the hand does not make the fracture open<\/li>\n\n\n\n<li><strong>Initial treatment:<\/strong> wound irrigation, debridement, and stabilization; specific protocols vary by institution and fracture pattern<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Practices that handle post-fracture rehabilitation, including hand therapy and physical therapy, move to subsequent encounter codes once active treatment ends. A later visit for a nonunion follows the same logic as <a href=\"https:\/\/pabau.com\/diagnostic-codes\/icd-10-code-s52262k\/\">S52.262K<\/a> in the forearm. The 7th character B applies only at the initial treatment visit.<\/p>\n\n\n\n<h2 id=\"h-icd-10-coding-guidelines-for-metacarpal-fractures\" class=\"wp-block-heading\">ICD-10 coding guidelines for metacarpal fractures<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The ICD-10-CM Official Guidelines for Coding and Reporting, maintained by CMS and NCHS, govern how fracture codes are assigned.

If a bone is named, use the bone-specific code.<\/li>\n\n\n\n<li><strong>Encounter type (initial):<\/strong> this is the first visit for active treatment.

That detail keeps an unspecified code out of a record where the specific bone was known. Tight documentation workflows at the point of care are the first defense against undercoding and payer queries.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.pabau.com\/cdn\/attachments\/pulse\/content-engine\/diagnostic_codes\/icd-10-code-s62349b\/customizable-consent-and-intake-forms.webp\" alt=\"Customizable consent and intake forms\"\/><figcaption class=\"wp-element-caption\"><em>Customizable intake forms prompt staff for wound and anatomical detail at the first visit, which supports an open-fracture code such as S62.349B.<\/em><\/figcaption><\/figure>\n\n\n\n<div style=\"height:35px;width:800px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">One additional rule from the official guidelines: fractures not specified as open or closed are defaulted to closed (7th character A) by convention.

Keeping the diagnosis code aligned with the documented fracture type prevents that conflict.<\/p>\n\n\n\n<h2 id=\"h-how-pabau-keeps-open-fracture-detail-on-the-claim\" class=\"wp-block-heading\">How Pabau keeps open-fracture detail on the claim<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In most practices the coder opens the chart after the visit is over. The operative note sits in one system and the claim is built in another. Anything the provider left vague, including whether the fracture was open, becomes a query days later.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Practice management software like Pabau holds the clinical note and the diagnosis code in the same encounter record. The coder reads the wound description and assigns S62.349B without leaving the chart. The code then travels into the claim with the note that justifies it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That matters most for the A-versus-B decision. When the open-fracture wording sits beside the code field, a closed-fracture code is much harder to submit by accident.

When the clinical record supports ICD-10 Code S62.349B, every qualifier matters: nondisplaced, base location, unspecified bone, open fracture, initial encounter. A single missing or incorrect qualifier lands the claim on the wrong code and starts a denial cycle.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Coders who read the wound description before choosing the 7th character rarely land on the wrong code. The fix is a documentation habit, not a billing rule. <a href=\"https:\/\/pabau.com\/book-demo\/\">Book a demo<\/a> to see how Pabau carries clinical documentation from the first encounter through to final submission.<\/p>\n\n\n        <div id=\"expert_picks\">\n            <div class=\"header\">\n                                    <img decoding=\"async\" src=\"https:\/\/pabau.com\/wp-content\/uploads\/2025\/11\/Expert-Picks.svg\" alt=\"Continue your research\" height=\"42\" width=\"42\">\n                                <h3>Continue your research<\/h3>\n            <\/div>\n            <div class=\"content\">\n                                                            <div class=\"item\">\n                            <div>\n                                <svg width=\"20\" height=\"27\" viewBox=\"0 0 20 27\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n                                    <path\n                                        d=\"M18.6223 14.3857C19.1246 13.8975 19.1246 13.1045 18.6223 12.6162L12.1938 6.36621C11.6915 5.87793 10.8759 5.87793 10.3737 6.36621C9.87143 6.85449 9.87143 7.64746 10.3737 8.13574L14.6125 12.2529H2.28571C1.57455 12.2529 1 12.8115 1 13.5029C1 14.1943 1.57455 14.7529 2.28571 14.7529H14.6085L10.3777 18.8701C9.87545 19.3584 9.87545 20.1514 10.3777 20.6396C10.8799 21.1279 11.6955 21.1279 12.1978 20.6396L18.6263 14.3896L18.6223 14.3857Z\"\n                                        fill=\"#54B2D3\" \/>\n                                <\/svg>\n                            <\/div>\n                            <p><strong>Need a compliant documentation workflow for hand injuries?<\/strong> <a href=\"https:\/\/pabau.com\/blog\/hipaa-compliance-for-medical-offices\/\">HIPAA compliance for medical offices<\/a> covers the data-handling standards behind every patient encounter record.<\/p>\n                        <\/div>\n                                                                                <div class=\"item\">\n                            <div>\n                                <svg width=\"20\" height=\"27\" viewBox=\"0 0 20 27\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n                                    <path\n                                        d=\"M18.6223 14.3857C19.1246 13.8975 19.1246 13.1045 18.6223 12.6162L12.1938 6.36621C11.6915 5.87793 10.8759 5.87793 10.3737 6.36621C9.87143 6.85449 9.87143 7.64746 10.3737 8.13574L14.6125 12.2529H2.28571C1.57455 12.2529 1 12.8115 1 13.5029C1 14.1943 1.57455 14.7529 2.28571 14.7529H14.6085L10.3777 18.8701C9.87545 19.3584 9.87545 20.1514 10.3777 20.6396C10.8799 21.1279 11.6955 21.1279 12.1978 20.6396L18.6263 14.3896L18.6223 14.3857Z\"\n                                        fill=\"#54B2D3\" \/>\n                                <\/svg>\n                            <\/div>\n                            <p><strong>Wondering how sequela codes differ from initial encounters?<\/strong> <a href=\"https:\/\/pabau.com\/diagnostic-codes\/icd-10-code-v8654xs\/\">V86.54XS<\/a> walks through the 7th character S and late-effect reporting.<\/p>\n                        <\/div>\n                                                                                <div class=\"item\">\n                            <div>\n                                <svg width=\"20\" height=\"27\" viewBox=\"0 0 20 27\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n                                    <path\n                                        d=\"M18.6223 14.3857C19.1246 13.8975 19.1246 13.1045 18.6223 12.6162L12.1938 6.36621C11.6915 5.87793 10.8759 5.87793 10.3737 6.36621C9.87143 6.85449 9.87143 7.64746 10.3737 8.13574L14.6125 12.2529H2.28571C1.57455 12.2529 1 12.8115 1 13.5029C1 14.1943 1.57455 14.7529 2.28571 14.7529H14.6085L10.3777 18.8701C9.87545 19.3584 9.87545 20.1514 10.3777 20.6396C10.8799 21.1279 11.6955 21.1279 12.1978 20.6396L18.6263 14.3896L18.6223 14.3857Z\"\n                                        fill=\"#54B2D3\" \/>\n                                <\/svg>\n                            <\/div>\n                            <p><strong>Documenting an injury with an external cause?<\/strong> <a href=\"https:\/\/pabau.com\/diagnostic-codes\/icd-10-code-w4909xd\/\">W49.09XD<\/a> explains encounter-type selection in the external cause chapter.<\/p>\n                        <\/div>\n                                                <\/div>\n        <\/div>\n    \n\n\n<h2 id=\"h-frequently-asked-questions\" class=\"wp-block-heading\">Frequently asked questions<\/h2>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1786603304893\"><h3 class=\"schema-faq-question\">What is ICD-10 Code S62.349B?<\/h3> <p class=\"schema-faq-answer\">ICD-10 Code S62.349B is a billable diagnosis code in the FY2026 ICD-10-CM edition. It represents a nondisplaced fracture of the base of an unspecified metacarpal bone at the initial encounter for an open fracture. The unspecified group covers metacarpals 2 through 5. It became effective October 1, 2025, and sits within the S62 fracture of wrist and hand category.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786603304894\"><h3 class=\"schema-faq-question\">Is S62.349B a billable ICD-10-CM code?<\/h3> <p class=\"schema-faq-answer\">Yes, S62.349B is a valid billable ICD-10-CM code. It carries the required 7th character (B) that makes the base code S62.349 billable. Without a 7th character, the base code is not accepted for reimbursement.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786603304895\"><h3 class=\"schema-faq-question\">What is the difference between S62.349A and S62.349B?<\/h3> <p class=\"schema-faq-answer\">S62.349A is used for a nondisplaced fracture of the base of an unspecified metacarpal bone at the initial encounter for a closed fracture. S62.349B is used when the fracture is open, meaning there is a wound communicating with the fracture site. The 7th character A or B is determined by the clinical record, not the coder.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1786603304896\"><h3 class=\"schema-faq-question\">What does the 7th character B mean in fracture ICD-10 codes?<\/h3> <p class=\"schema-faq-answer\">In ICD-10-CM traumatic fracture coding, the 7th character B designates an initial encounter for an open fracture.
